34 xcv. ASCLEPIADE.S. (J. D. Hooker.) [G&ngronema. 



MALACCA (? Finlayson), Griffith, Maingay (Kew Distrib, 1113). 



Leaves 3-6 by 1-2 in., firmly membranous ; nerves 5-6 pairs, arched ; petiole 

 \ | in. Cymes small ; pedicels very unequal. Sepals small, oblong. Corolla \ in. 

 diam., lobes spreading. Coronal- scales broad, recurved, apparently confluent with 

 the anther-base. Anther-tips large, exserted. Follicles 6 by ^ in., gently curved 

 from base to tip, smooth. Seeds ^ in. oblong, wing broad recurved. Finlayson's 

 specimens in Herb. Wallich have no locality given. 



3. G. ventricosum, Hook. f. : quite glabrous, leaves coriaceous ovate 

 or ovate-lanceolate obtusely caudate-acuminate, cymes subsessile few-fld., 

 corolla-tube glabrous within, lobes as long linear with recurved margins. 



KHASIA MTS. (Herb. Calcutta). 



Leaves 3 by 1-1 in. ; nerves 2-3 pairs, very prominent beneath, strongly inarch- 

 ing far within the margin ; petiole stout, ^-^ in. Flowers very shortly pedicelled. 

 Sepals very small. Corolla ^ in. long. Coronal- scales broad, recurved. Pollen-masses 

 smaller than the corpuscle. In form of corolla this a good deal resembles Gymnema 

 Thomsoni. I have seen only a solitary indifferent specimen of this plant. 



Gr. ? FIJTLATSONII, Dene, in DC. Prodr. viii. 625 (Gymnema Finlaysonii, Wight 

 Contrib. 46 ; Wall. Cat.), is probably, like most of Finlayson's plants, from Siam. It is 

 glabrous with ovate-cordate leaves, and has peduncled cymes of large flowers ^-| in. 

 diam. The pollen-masses have long spiral pedicels. 



32. BXARSDENXA, Br. 



Twining, rarely erect, shrubs or undershrubs. Leaves opposite. Cymes 

 umbelliform, simple or branched, terminal or axillary ; flowers medium-sized 

 or small. Calyx 5-partite. Corolla campanulate or urceolate or salver-shaped, 

 lobes narrow or broad, overlapping to the right. Coronal scales 5, usually 

 subulate flattened (or 0), adnate to the anthers dorsally, erect. Column short; 

 anthers with an inflexed tip ; pollen-masses pedicelled, oblong or ovoid, waxy, 

 erect. Stigma flat convex or beaked, sometimes very long. Follicles lanceolate 

 or poniard-shaped. Seeds comose. DISTRIB. Species about 50 ; chiefly tropical 

 or subtropical, with one S. European. 



A heterogeneous assemblage, amongst which perhaps M. tinctoria, eriocarpa, and 

 thyrsoidea should form one natural genus, and the remainder a second. M. thyrsoidca 

 is very remarkable in wanting the coronal scales. 



SECT. I. Eumarsdenia. Floivers small. Corolla cylindric, shortly 

 5-cleft, mouth closed with a brush of short hairs. Column minute ; anther- 

 tips and coronal scales very short. Stigma truncate. 



1. HI. tinctoria, Br. in Mem. Wern. Soc. i. 30; nearly glabrous, leaves 

 ovate or cordate acuminate or caudate, flowers in dense thyrsoid or rounded 

 panicles, coronal scales subulate longer and narrower than the anther-tip, 

 follicles finely pubescent. Wight Contrib. 40, and Ic. t. 589 ; Wall. Cat. 8173 ;
