white spirals round about the just flowering spadix. — The description 

 is taken from a living spécimen cultivated in the Buitenzorg Gardens, 

 flowering and fruiting December 1919 and January 1920. 

 Habitat unknown, 



Raphidophora pilosula, V. A. V. R., this Bull , P, 1Q20, 386. 



Scandent. Pétiole with the knee flattened, slightly canalicuiate and 

 narrowly 2-cristate on the anterior side; lamina above emerald-green, ben- 

 eath paler, vvhen young glaucous, when dry slightly asperulous by numerous 

 very minute and densely crowded points, except on the primary veins; 

 Costa beneath when fresh apparently smooth, when dry apparently prov- 

 ided among the hairs with a very thin layer of tomentum. ') 



The spécimen on which 1 founded this species has originally been 

 cultivated in the Buitenzorg Gardens under the name of R. oblongifolia 

 SCHOTT, which, according to the diagnosis given by Enqler and Krause, 

 is distinguished also in having the spadix provided with a stalk about 

 1 cm. long, whilst in this species the spadix is sessile. — ENQLER and 

 KRAUSE's fig. 10 C (Pflzrch, XXXVll, IV 23 B), however, shows (errone- 

 ously?) a sessile spadix. 



A fruiting plant gathered in Sumatra {Dell, Bandar-baroe, J. A. LôRZiNQ 

 No. 5913, 11 August. 1918, primeval forest, ait. + 1000 m.) agrées very 

 well with this species. It is distinguished in having the caudex climbing 

 to + 15 m. high, the pétiole and lamina of the fully developed leaves 

 longer, to 35 cm long, the base somewhat more acute, the primary veins 

 more numerous, 20—30 on a side, the fructiferous spadix 12 — 14 cm. 

 long, 2 cm. thick, apparently stalked (i.e. the spiral-shaped Une of insertion 

 of the base of the spathe is rather open), the berries pauci (+ 2 — 6)- 

 spermous. 



Raphidophora Hallieri, V.A.V.R. this Bull., P, 1920, 385. 



The leaves of this species agrée nearly exactly with those of LôRZiNG's 

 Sumatran plant mentioned under R. pilosula V.A.V.R. but 1 could not find 

 a single hair in the costal pseudo-tomentum which, moreover, is less 

 distinct. — R. puberula Engl , which is unknown to me, seems at any rate 

 nearly allied with this and the preceding species; it is, however, described 

 as having ail the veins slender, whilst in this and the preceding species 

 the primary and secondary veins are distinctly différent. 



Raphidophora scaberula, V. A. V. R. 



Planta scandens, usque 3 m. vel plus alta. Foliorum petiolus + 47'/2 cm. 

 longus, antice canaliculatus et fere usque ad médium geniculi 3 cm. longi 



') This spurioiis tomentum is caused by tiie présence of innumerable* very 

 minute capitate-clavate papillae that can be seen by high magnifying poweronly; in 

 the dried plant thèse papillae become somewhat contracted, and more distinct when 

 seen under a commun lens, then giving tlie costa beneath a very thinly tomentose 

 aspect.
