columnar. Follicle* long. Seeds long, linear, truncate or narrowed (not beaked) 

 at both ends, glabrous, tipped with a deciduous coma, albumen not thick; 

 cotyledons linear, flat, radicle short. DIBTRIB. Species 7, a Cingalese, a 

 Malayan, and 5 African. 



1. B. acuminata, JBenth. in Gen. PI. ii. 719 ; leaves oblong obtusely 

 caudate-acuminate pale beneath glabrous, cymes terminal and axillary corymbose 

 puberulous shorter or longer than the leaves. Oleghornia acuminata and cymosa, 

 Wight Ic. t. 1310, 1312; Walp. Ann. iii. 43; Thwaites Enum. 194. 



CEYLON ; common in the central province, alt. 3000 ft. 



A slender climber. Leaves 3-4 by 1-1 in., rather thin ; nerves quite horizontal, 

 Tery slender ; petiole - in. Cymes trichotomous, peduncle slender ; pedicels short. 

 Flowers in. long. Calyx* about half as long as the calyx-tube, glands between the 

 sepals connate in pairs. Corolla glabrous or puberulous ; lobes oblong or linear 

 obtuse; tube and throat hairy within. Follicles 6-10 by in., cylindric, smooth. 

 Seeds \\ in., slender, narrowed at both ends. The corolla-lobes are much too short 

 And rounded in Wight's figure. 



2. B. malaccensis, Hook.f. ; leaves oblong or elliptic obtusely caudate- 

 acuminate pale beneath glabrous, cymes terminal and axillary paniculate gla- 

 brous longer than the leaves. 



MALACCA ; Maingay (Kew Distrib. 1094). 



Very closely allied to B. acuminata, but more slender, leaves smaller, 2 by f-1 \ 

 in., more membranous, whiter beneath, cymes more panicled than corymbose ; the 

 flowers are almost identical, except that the glands are solitary between the sepals 

 according to Maingay's mss. Fruit not seen. 



33. AGANOS1KA, G. Dan. 



Stout evergreen climbers. Leaves opposite. Flowers in terminal tomentose 

 cymes, large or middle-sized. Sepals narrowly lanceolate, acuminate, with 

 subulate glands at the base, rarely oblong ovate. Corolla salver-shaped, tube 

 very short ; throat long, cylindric, with bearded longitudinal bands behind the 

 anthers ; lobes lanceolate .linear-oblong or broad and rounded, overlapping to 

 the right and nearly straight in bud. Stamens at the base of the throat, in- 

 cluded ; anthers sagittate, rigid, conniving over the stigma and adnate to it, 

 cells spurred at the base. Disc 5-lobed, cupular. Carpels 2, distinct, tips 

 hiraute, rarely glabrous, many-ovuled; style short, top urn-shaped, truncate, 

 stigma columnar. Follicles short or long, terete, straight or curved, linear, 

 Seeds ovate or linear-oblong, flattened, glabrous, not beaked, albumen scanty ; 

 cotyledons oblong, radicle short. L)ISTRIB. Species 5, Indian and Malayan. 



The very different aestivation of the corolla requires the separation of this genus 

 from Ichnocarpus. 



SECT. I. Amphineurion, A. DC. Sepals ovate-oblong, acute. Ovary 

 .glabrous, half sunk in the disc. Follicles very long, cylindric. 



1. A. marginata, G. Don Gen. Syst. iv. 77; glabrous or branches and 

 leaves beneath pubescent, leaves oblong acute acuminate or caudate, nerves very 

 strong beneath inarching within the margin, cymes lax, corolla glabrous, tube 

 rather longer than the acute calyx-segments, lobes linear obtuse. Wight Ic. t. 

 425 ; A. DC. Prodr. viii. 433 ; Kurz For. Fl. ii. 186. A. acuminata, G. Don. 

 J.c.; Wight Ic. t. 424; A. DC. I.e. 434. A. macrocarpa, A. DC. I.e. 434.
