(Gramineae) is a very curious genus in mountainous areas of the palaeotropics, currently with two species. Curious because of its distribution: one species in Africa [Cameroon, Ethiopia, Kenya, Malawi, Tanzania, Uganda, S Africa (Natal), and Zimbabwe], Reunion, and then "suddenly" in Malesia (E Java, Lombok, Luzon). Recently a second species was described from the Nilgiris, Tamil Nadu, S India, S. sanjappae (Kabeer & Nair, 2006). With such a disjunction it is no wonder that three generic names have been pub- lished for it: Koordersiochloa Merr. (Malesia), Pseu- dostreptogyne A Camus (Reunion), and Stre- blochaete Hochst. ex Pilg. (Africa). Curious also because of the diaspore that consists of gyros copically intertwining awns whereby the spikelets fall as a single unit, a so-call tangle-head, that adheres to fur or may be distributed by the wind. Chippendall (1955) commented that the awns and the sharp, bearded calli cause intense discomfort and irritation. The name Streblochaete first appeared on the labels of exsiccatae collected by Schimper in Ethi- opia in 1840 and 1842 and distributed by Hochstet- ter. The first collection was labeled as S. koestlinii (Hochstetter 412; L!) (Hochstetter, 1841) and the later one as S. nutans (Hochstetter II, 683; L!). There are no descriptive notes on the labels. The first one was described by Richard (1851) as Dan- thonia koestlinii (ckostlini) with Streblochaete kostlini in the synonymy, the second collection as Trisetum longiaristum, with Streblochaete nutans as a synonym. Richard did not realize that the Bromus trichopodus A Rich, he described simultaneously was the same species. The validation of the generic name is generally attributed to Pilger (1906). He wrote (my translation from the German): "With reason Stapf in his identification of the Gramineae in the Flora capensis has distinguished several genera from the real Danthonias... Several real Danthonias occur in Abyssinia, however, 2 forms have here been united with the genus to which they do not belong...To be excluded is the form which has been distributed by Hochstetter as Streblochaete nutans, which howev- er Richard already mentions under Danthonia. Here the glumes are much shorter than the spikelets, nar- row, the lower 3-nerved, the upper 5-nerved; the callus of the lemma is 2 mm long, shortly stiffly white hairy, distinct from the equally long lower part of the rachilla joint, the lemma is narrow, strongly 7-nerved, and which that is by itself defini- tive, [his emphasis] from the back awned from be- low bom short points; the awn is very long, be- coming upwards very weak, enmeshed with the awns of the other lemmas; the palea is 2-keeled .300 REINWARDTIA [VOL.13 near the middle, in between infolded; the flower is bisexual. Nothing to do with Streblochaete nutans is a species, which Hochstetter first indicated as Streblochaete Kostlinii, later as Danthonia Kostlinii. This species is according to the nervature and awning a real Danthonia. The question is what exactly Pilger is describing here: a specimen, a species, a genus? Granted, the characters obtained from the collection of Streblochaete nutans are apparently generic ones (except for the callus being 2 mm long) and are intended to show that this is not a Danthonia. He calls it a form and implicitly a species. He apparently accepts Hochstetter's Danthonia Kostlinii as a true Danthonia, but what is the generic placement of S. nutansl There is no explicit statement that we have the (new) genus Streblochaete here and therefore he cannot be regarded to have established the generic name. Just the word 'Gattung' (genus) would have been so use- ful. The provisions of the International code of botanical nomenclature cited below are those of the Vienna Code (McNeill et al., 2006). The exact wording of the Code of Melbourne (2011) was not yet available during the writing. It was not expected that there would be significant changes. It can be argued that he did intend to have Streblochaete as the name of a (new) genus. This is enforced by the note on Schimper II. 683, where Hochstetter wrote 'n. g. e. tribu. Avenacearum Danthoniae affine - Ejusdem generis etiam Dan- thonia Kostlini Hochst. in prima sectione nr. 412, quae nunc mihi Streblochaete kostlinf. ('New ge- nus related to the tribe Danthonia of the A venace- ae - Danthonia kostlini Hochst in the first section nr. 412 is also of the same genus, which now is my Streblochaete Kostlinf). Good intentions, however, are insufficient. Article 34. l(d) (see Ex. 1 for a case similar to but not identical with the pre- sent one) states 'A name is not validly published ... (d) by the mere mention of the subordinate taxa included in the taxon concerned'. Therefore Streblochaete nutans is invalid here (Art. 43.1). Obviously Art. 42.1 (descriptio generico- specifica) does not apply, as Streblochaete nutans does not refer to a new species, as the name was already cited as a synonym of Trisetum longiaristum by Richard (1851). If one remains convinced that Pilger validly described Streblochaete in 1906 the combination S. nutans is superfluous. One obvious slip of the pen is that Richard would have placed it in Danthonia. He included it in Trisetum. It was Engler (1892) who regarded it as a Danthonia. Another is that Hochstetter first (label of Schimper 412) called the collection Danthonia koestlinii and later (label of Schimper II 683) Streblochaeta koestlinii, and not the other way around. Incidentally, this is not a Danthonia at all, but Phaenanthoecium koestlinii (Hochst. ex A Rich.) C.E. Hubb., a monotypic genus. In 1927 Pilger validated Streblochaeta with S. longiaristum as the only species, and said (my translation) "For the characters of the genus see Pil- ger ... 1906". Before 1935 a description was not required to be in Latin (Art. 36.1), so there seems to be nothing wrong with this. Pilger does not give any intervening publication where the name (inadvertently) might have been validated, and I have found none. C.E. Hubbard (1936) concurred, stating 'In 1906 Pilger ... supplied a short generic description'. Apparently because of these statements Streblochaete (1906) was entered in publications and databases like IPNI. Unfortunately, between 1906 and 1927 Koordersiochloa had been published by Merrill (1917) and thus this is the correct name for the genus. It is tempting to propose to conserve the "well-known" name Streblochaete over the "obscure" name Koordersiochloa. This seems ill-fated, as the two species are so very rare and of little importance in ecology, conservation, or general use. I am not sure who was the first to discover that Koordersiochloa javanica Merr. and Streblochaete longiarista were identical. Possibly it was Hubbard (1936). Koordersiochloa Merr.

Lod- icules 2, free, cuneate, fleshy, truncate. Anthers 3. Ovary glabrous. Caryopsis with an adnate peri- carp, dorsally furrowed, embryo ca. 0.1 the length of caryopsis, hilum punctiform (F+FF in Reeder's classification, 1957; fide Tateoka, 1965). Distribution. 2 species in Tropical Africa and S Africa, Reunion, India (Tamil Nadu, Nilgiris), Malesia (Java, Lombok, Philippines). Notes. Over time Streblochaeta has been placed in various pooid groups (Tateoka, 1965). Corrected for current nomenclature these are Brachypodieae Harz, Bromeae Dumort., Danthonieae Zotov, and, usually, Poeae (which before the rule of autonyms often was called Festuceae Dumort.). Tateoka (1965, 1969) based on morphological, anatomical, and cytological data regarded it to belong to the Meliceae Rchb. which is presently generally accept- ed (Clayton & Renvoize, 1968; Watson & Dallwitz, 1996). Perhaps because of this, Mejia- Saules & Bisby (2000) included it in a phenetic analysis of the Meliceae and found it either nested within Melica L. and next to the N. American / Siberian Schizachne purpurascens (Torr.) Swallen, or basal to the tribe. A D N A sequence comparison using tmL was promised, but I have not found it. The free lodicules and punctiform hilum are aberrant for the tribe. A molecular analysis in a broad context would be illuminating. Prompted by a query of a reviewer I here add some notes on the caryopsis and its parts. Unfortunately, I have not seen any of K. longarista and their description has been taken from various sources. Whenever they were mentioned the authors agreed that the embryo and hilum are small. The dorsal furrow is therefore not the hilum. For illustrations see Camus (1930), Jacques-Felix (1962, 'hilum ... peu visible', hilum hardly visible). Clayton (1970) and Launert (1971) used the same plate, but cited different sources for the caryopsis. Especially Tateoka (1965: t. 2, 3) was quite specific and illustrated sections of the embryo ('very small relative to the endosperm ... embryo and hilum are very small'). Kabeer & Nair (2006) depicted S. sanjappae, but did not describe details of the fruit. The description of K. longarista is based on Malesian material because I am writing an account for this area and it was beyond the scope of this essentially nomenclatural note to make a revision of the genus. The few African specimens seen did not appear to differ significantly. I have not seen any material of K. sanjappae. Key to the species la. Stolons absent. Spikelets solitary.
