192 MR. H. N. RIDLEY ON PLANTS 
A very distinct species of this small genus with its rigid coriaceous leaves, and stiff 
terete, sometimes branched stems, three-lobed lip, and distinct rounded spur-like mentum. 
The whole plant dries black; the flowers appear to have been deep purple except the lip, 
which looks whitish. The genus Poephyllwm was formed by myself to include a plant 
described by Sir J. D. Hooker as Agrostophyllum pauciflorum, and transferred at first 
by me to Erie. It was published in ‘ Materials for a Flora of the Malay Peninsula,' 
Monocot. vol i, in the early part of the year 1907. By some error, the printer in 
printing a general title-page to the whole three volumes put the date 1908 (the date of 
the printing of the index) instead of 1907. The same year, but apparently a month or 
two later, J. J. Smith published another species of the same genus under the name 
Lectandra parviflora, n. gen. & sp., in the ‘Bulletin du Département de l'Agriculture 
aux Indes Néerlandaises, xiii. (1907) p. 59. The genus Poephylium I believe, therefore, 
ante-dates Lectandra. The species known are P. pauciflorum, Ridl. (Malay Peninsula), 
P. parviflorum (Lectandra parviflora, J. J. Sm.) (Java), P. podochiloides ( Trichotosia podo- 
` ehiloides, Schlechter) (New Guinea), and the species described here for the first time.
