INTRODUCTION There are major changes in the classification of vascular plant through the publication of APG I- III and the lycophyte and fern linear sequence. The- se two attempt to present a convenience sequence to be applied in specimens arrangement, listing in flo- ra, books, indices, etc., which is claimed to be more natural and reflecting evolutionary relationship (Christenhusz et al, 2011a; Haston et al, 2009). Both classification are much appreciated as sort of solution to the present classification, generated using the most recent research result, mainly by means of molecular approach. Nevertheless, contro- versies are still to remain. It is often the result of molecular studies is rather discordance with con- ventional or morphological observations. Some re- lationships are sound impossible or rather not con- vincing because of inadequate sampling. Hence, there are suggestions to consider appropriate adjust- ment in the application (Hawthorne & Hughes, 2008; Sheperd, 2008; Stace, 2010). Herbarium Bogor (BO) has been adopted sequence presented in the first volume of Flora Malesiana series II, written by Holttum, for Malesi- an ferns and fern allies collection, that sorted in al- phabetical order. As he mentioned in his introduc- tory note (1959), the groupings might changed in the final re-assessment at the conclusion of the treatment. After three volumes, there are significant departures in the families or genera groupings. The revision has covered 15 families and groups until 1998. The remaining taxa mostly are the large or difficult ones that in total occupy considerable space in the herbarium. As the national herbarium, BO is referred for the correct plant identification in botanical research and works of, especially, university students in the country. This service is also considered as an effec- tive way for disseminating updates of related re- searches. BO consistently follows Flora Malesiana as the most practical way to carry the service. How- ever, the flora is problematic to some extent. Mean- while, the expected better and new fern classifica- 367 368 REINWARDTIA [VOL.13 tion in Christenhusz et al. (2011a), with its subse- quent papers, is somewhat different to the overall flora sequence. There has been no attempt found to synchronize Flora Malesiana with the new classifi- cation of fern and lycophyte. This paper reviews the two sequences and proposes the best alternative for the alignment of families and genera of Malesian fern in BO. Contrasting Flora Malesiana sequence to the New Classification Stace (2010) mentioned that adopt new dif- ferent classification often halted predominantly for the reason of unfamiliarity. To our observation, the most recent classification of fern and lycophyte (Christenhusz et al, 2011a, 2011b, 2011c) which is largely based on the works published in Smith et al. (2006), later is partly refined by Rothfels et al, (2012), is obviously different from the previously adopted in BO but clarifies relationship in some groups of taxa. It is quite unusual to group the Grammitids with other Polypodiaceae, or having Pteridaceae enlarged with Adiantoids and Vittarids. However, the inclusion of Ctenitis and Lastreopsis to Dryopteridaceae is a lot more sensible than to lump them in Tectaria Group. Some switching of taxa is already predicted but some newly recognized families are fairly atypical. In the first volume of Flora Malesiana (1959), Holttum begun the indecisive fashion of delimiting fern family, ended up with groups of genera. Most part of the first and second volume of revision covered by the same person which causes such de- limitation quite common. The label "group" often confused students that further oblige explanation. However, the revision is very functional in identify Malesian fern specimens. Problems occur whenever one deals with untreated genera that excluded from its initial group. Table 1 is presented as an attempt to decipher the discrepancies between the two sequences.

This genus is included in Psilotaceae, see row 27 phabetically as applied in specimen arrangement in BO. Later in the table, these two are referred as FM II classification. The explanation in column "Notes" refers to genera listed in the fourth column ("Classification in Christenhusz et al. (2011a, c)") contrasted to the FM II classification. Some genera are underlined; refer to those that not included in the particular family or group in the FM II classifi- cation. The genus/genera written before the equal sign "=" is coming from the FM II classification, considered as the synonyms of the genus written afterward in the Christenhusz' classification. The table is confined to families and genera occurred in Malesian region. Preferred option for BO Good classification should reflect systematic relationship among the taxa, thus provides high lev- el of predictivity which then will endure for the foreseeable future (Stuessy, 2009; Stace, 2010). The new classification (Christenhusz et al., 2011a and its subsequent papers) is based on fairly large data set of the most recent studies which then confident- ly expected to perform a good classification. How- ever, applying new sequence must consider careful- ly the cost of shifting. First, possibility of signifi- cant change to the classification is always present in the future. Second, rearranging hundreds of pigeon- holes would demand a lot of time and resources which is fairly limited. Third, BO has priority of work, i.e. contribute in finishing the Flora Malesi- ana revision, rather than to deal with undone new combination caused by splitting or lumping genera. It is here, proposed BO to adopt these following actions for the Malesian fern collection arrangement and flora listing: 1. For genera in the indecisive groupings after FM II revision, their placement in the family could follow linear sequence in Christenhusz et al. (2011a, c) and the subsequent papers. This would dismiss the confusion over the term "group" and provide the right niche for genera excluded from the flora revision. For example, in the Tectaria group of FM II revision, some 2012] WARDANI et al.: The new pteridophyte classification in the Herbarium Bogoriense (BO) 375 3. of the genera included are more often consid- ered closer to dryopterids. Hence, this grouping leads to the confusion over delimiting the later. Moreover, Hypodematium, was initially included in the Tectaria group, after the revi- sion were left alienated. However, it must be anticipated that changing arrangement in this two groups according to the more recent linear sequence will result in considerable space is- sue, and proposing over than 20 new combina- tions is in necessity. This is partly because some members of the Lomariopsis group and Lindsaea group in FM II revision are involved. Nevertheless, it is recommended not to discern the new combinations. Other than change the placement of genera in families, it is preferable to entrust them as revised in the flora. For genera in families after revision, the placing shall be kept as in revision instead of following the more recent linear sequence. The later option will caused the necessity to create many new combinations or to do nomenclatural corrections, as happen earlier in the ferns of Thailand (Lindsay & Middleton, 2009). The most noticeable example is Cyatheaceae and Thelypteridaceae. The splitting of Cyathea to four genera and lumping 22 genera in Thelypteridaceae to six will generate nomen- clatural problems. Instead of creating new names and doing more changes in specimen order, since BO sort specimen alphabetically, it is best to leave them as the current arrangement based on the flora. For genera that are not yet revised, they should be treated the same as treating the indecisive groups. However, whenever the flora updated and the sequence is somewhat different to the new classification, it is preferable to priorities the Flora. There will be none or minor changes to specimen arrangement in families with simi- lar member of genera. Initial group with slight- ly mixed genera would have to split, such as Athyria group to three families (see Rothfels et al., 2012 for Diplaziopsidaceae), or Dennstaed- tia group to two families. This alteration in- volves only few species that would not generate space problem. However, families with medi- um to voluminous combination of genera such as Dryopteridaceae with additional member coming from Tectaria group and Lomariopsis group; Pteridaceae with the adiantoids and vit- tarids appended; also Polypodiaceae enlarged with grammitids, will require extra rooms. The revised genera of Polypodiaceae shall be sorted as in the flora while the untreated one such as Loxogramme and grammitids fern shall be ar- ranged as in the recent linear sequence. In summary, the Malesian fern collection in BO would be arranged according to the following sequence (in alphabetical order): Aspleniaceae Asplenium Hymenasplenium Athyriaceae Anisocampium Athyrium Cornopteris Deparia Diplazium Azollaceae Azolla Blechnaceae Blechnum Brainea Stenochlaena Woodwardia Cheiropleuriaceae Cheiropleuria Cyatheaceae Cibotium Culcita Cyathea Cystodium Dicksonia Cystopteridaceae Cystopteris Gymnocarpium DavaHiaceae Davallodes Davallia Leucostegia Dennstaedtiaceae Dennstaedtia Histiopteris Hypolepis Microlepia Monachosorum Paesia Pteridium Diplaziopsidaceae Diplaziopsis Dipteridaceae Dipteris Dryopteridaceae Acrophorus Arachnoides Arthrobotrya Bolbitis Ctenitis Diacalpe Dryopolistichum Dryopsis Dryopteris Elaphoglossum Lastreopsis Lomagramma Polystichum Polystichopsis Rumohra 376 REINWARDTIA [VOL.13 Stenolepia Teratophyllum Equisetaceae Equisetum Gleicheniaceae Dicranopteris Gleichenia Hymenophyllaceae Callistopteris Cephalomanes Didymoglossum Hymenophyllum Trichomanes Vandenboschia Hypodematiaceae Didymochlaena Hypodematium Isoetaceae Isoetes Lindsaeaceae Lindsaea Odontosoria Sphenomeris Tapeinidum Xyropteris Lomariopsidaceae Cyclopeltis Lomariopsis Thysanosoria Lycopodiaceae Huperzia Lycopodium Lycopodiella Marattiaceae Angiopteris Christensenia Ptisana Matoniaceae Matonia Phanerosorus Marsileaceae Marsilea Nephrolepidaceae Nephrolepis Oleandraceae Oleandra Ophioglossaceae Botrychium Helmintostachys Ophioglossum Osmundaceae Leptopteris Osmunda Plagiogyriaceae Plagiogyria Polypodiaceae Acrosorus Aglaomorpha Arthromeris Calymodon Christiopteris Chrysogrammitis Cochlidium Ctenopterella Dasygrammitis Drynaria Goniophlebium Grammitis Lecanopteris Lemmaphyllum Lepisorus Leptochilus Loxogramme Micropolypodium Microsorum Oreogrammitis Paraselliguea Platycerium Podosorus Polypodiopteris Prosaptia Pyrrosia Radiogrammitis Scleroglossum Selliguea Themelium Thylacopteris Xiphopterella Psilotaceae Psilotum Tmesipteris Pteridaceae Acrostichum Adiantum Anogramma Antrophyum Aspleniopsis Austrogramme Ceratopteris Cerosora Cheilanthes Coniogramme Doryopteris Haplopteris Hemionitis Monogramma Notholaena Onychium Pellaea Pityrogramma Pteris Syngramma Taenitis Vittaria Saccolomataceae Orthiopteris Saccoloma Salviniaceae Salvinia Schizaeaceae Lygodium Schizaea Selaginellaceae Selaginella Tectariaceae Aenigmopteris Arthropteris Pteridrys Pleocnemia Psomiocarpa Tectaria Thelypteridaceae Ampelopteris Amphineuron Chingia 2012] WARDANI et al.: The new pteridophyte classification in the Herbarium Bogoriense (BO) 377 Christella Coryphopteris Cyclogramma Cyclosorus Macrothelypteris Mesophlebion Metathelypteris Nannothelypteris Parathelypteris Phegopteris Plesioneuron Pneumatopteris Pronephrium Pseudocyclosorus Pseudophegopteris Sphaerostephanos Stegnogramma Thelypteris Trigonospora ACKNOWLEDGEMENT The corresponding author would like to thank Dr. Peter Hovenkamp for his valuable information in fern specimen arrangement at L and progression in the Flora Malesiana Series II revision.
