INTRODUCTION Liou Ho, who established the genus Neocinnamomum in 1932, treated 5 species (N. delavayi, lecomtei, parvifotiutn, poilanei and yunnanense) of which I chose N. detavayi as the lecto-type species. Liou Ho differentiated the genus mainly by the position of the 4 cells of the anthers, which in Cinnamomum are placed in pairs above each other, in Neocmnamomum at the same level, one pair being introrse or extrorse, the other lateral. This character, however, is found only in JV. detavayi and to a lesser extent in JV. caiulatum, in the other species the pairs of cells are in pairs above each other and this induced me {in Reinwardtia 4, 1957) to include the genus in Cmnamnmwm. Although the position of the anther cells cannot be used as a generic characteristic (which is also true for all other genera of Lauraceae), I have reinstated the genus, because of the peculiar inflorescence, the thick, fleshy, obconical, shallow fruit cup with persistent, enlarged tepals and the distichous leaves. However, the genus remains very near to Cin n amomum. — 85 — REINWARDTIA [VOL. 9 Of the 5 species recognized by Liou Ho, I have reduced 3 to synonymy {N. •parvifoliwm and poilanei to W. detavayi and N. yunnanei'se to N. caudatum). N. wilsonii Allen, based on a specimen from Szechuan, is not different from Cinnamomum fargesii from the same Province. Lecomte described the fruit of the latter (which Allen overlooked!) which conforms with those of the other Neocinnainomum species. In leaf and inflorescence characters this is a true Neocirmamtmium. The position of the enigmatic N. meko-ngev.se is problematic. The typo material could not be examined, but the description conforms very well with the specimens enumerated here. The glabrous branchlets places it near N. fargesii but it has sericeous flowers, hence it might be a hybrid between N. delavayi and N. fargeaii, although this is not very likely. I have excluded N. confertiflorum from the genus, as the fruit cup are different from those of Neocinnamomum. The species belongs to the genus Litsea and should be renamed: Litaea confertiflora (Meissn.) Kosterm., comb. nov. (basionym: Actinodaphwe confertiflora Meissner in DC., Prodr. 15(1): 219. 1864). DISCUSSION ON MORPHOLOGICAL CHARACTERS S t e m . All species are shrubs or small trees with slender, cylindrical branchlets. The end buds are small and provided with one or two tiny bud scales, which distinguish them from subgenus Camphora of Cmnamomum, which has spirally arranged leaves but very large perulate end buds. L e a v e s . At first sight the leaves and their phyllotaxy remind one strongly of Liiidera. The leaves are very uniform in shape and texture with conspicuous acumen and a rounded base with a small cuneate centre and leaves which tend to become very broad. The leaves are always trinerved, only in N. caudatu-m the basal nerves reach the acumen. N. caudatum can be recognized even from the leaves alone by the numerous parallel secondary veinlets, which produce elongated areoles. The leaves are as a rule distichous, the apical ones may be sub-opposite. At the junction of the basal laterals and the midrib often deep, partly covered domatia are present, sometimes produced as a slight swelling on the upper leaf surface. The petiole is always slender and channeled above. I n f l o r e s c e n c e . The common inflorescence is a peculiar kind of panicle, the main peduncle stiff and well-developed, but the lateral 1974] KOSTERMANS: The geteas Neoc branches strongly reduced, the flowers forming pseudo-glomerules, actually a very short, bracteate branch, bearing 1—i spirally arranged flowers on long, slender pedicels. This I consider the primitive kind of inflorescence and is only found in N. caudata. Occasionally such panicles are found in other Lauraceous genera (Akeodaphne •petiolaris, many species of Caryodaphnopsis). Sometimes the apical part of the branches has no leaves and the axilar panicles form a compound, large, terminal panicle (N. caudata, a specimen with terminal panicles was described as iV. yunnamense). In most species, the main peduncle is strongly reduced or more or less lacking, and the pseudo-glomerules of flowers become more or less sessile (a remnant of the bracteate peduncle is, however, always present). F l o w e r . In all species the flowers are more or less identical differing only in their pubescence and the position of the anther cells. The tepals are almost equal in length, although the inner ones arc- somewhat narrower, they are rather fleshy. The stamens are included, have well-developed filaments and are arranged in 3 whorls, the fourth is staminodial. Liou Ho was struck by the position of the 2 pairs of cells in N. delavayi, where the lateral pair is almost in one level with the oxtrorse or introrse pair. Actually they are not exactly in one plane and intermediate stages between this and the normal superposed pairs occur in other species (N. fargesii). As usual in Lauraceae, the position of the anther cells cannot be used as a generic character, as it varies within the species of one genus. The small, but conspicuous staminodes are similar to thos.e in Cinnamomum and so is the peltate, small stigma. F r u i t . A distinctive feature of the fruit is the fleshy, swollen, obconical, large, but at the top very shallow cup with persistent, enlarged fleshy, erect or patent tepals. The fleshy cup merges into a slightly obconical, slender and long pedicel. The fruit itself is of the common type in Lauraceae. NEOCINNAMOMUM Liou Ho Liou Ho, Laur.

Merrill was right when he referred Cinnammnwm eaudatum Nees to Neoeinnamoitiwrn, but included wrongly the Sumatra material, which shows the reticulation and shape of inflorescence of N. delavayi, not that of C. eaudatum.. The fact, however, that the mesh of the reticulation is wider than that in C. delavayi and that the inflorescence is reduced to a single flower, compels me to accept this as a different and imdes- cribed species.
