37. PYCNOBOTRYA, Benth. in Benth. et Hook. f. Gen. 

 PI. ii. 715. 



Calyx small, subcoriaceous, eglandular; sepals almost free, im- 

 bricate, ovate, obtuse. Corolla funnel-shaped-campanulate ; tube very- 

 short with 5 much projecting ridges extending from the sinuses- 

 towards the base and with 5 others alternating with them and 

 slightly raised ; lobes 5, oblong, obtuse, overlapping to the left. 

 Stamens inserted near the base of the corolla-tube; filaments 

 very short, flattened ; anthers conniving in a cone, included, lanceolate, 

 acute, sagittate ; appendages much shorter than the polliniferous part ; 

 tails very short, subacute ; foot of the connective broad, with a large 

 papillose projecting cushion in the centre. Disc 0. Carpels 2, free. 

 Style very short ; stigma capitate, very minutely papillose except on 

 the minute bifid apiculus; ovules 4 in each carpel, 2-seriate. Fruit 

 unknown. — Climbing shrubs. Leaves opposite or in whorls of 3^ 

 coriaceous, with faint and closely set parallel nerves ; axillary stipules 

 ; axillary glands scanty, minute. Flowers small, in few- or many- 

 flowered contracted cymes, gathered in terminal, often many-flowered,, 

 leafy panicles or corymbs. 

 Species 2, endemic. 



Although the fruit of this genus is not known, the limited number of ovules and 

 the fact that the upper 2 show signs of early decay make it almost cei tain that the 



fruit is not of the usual JEchitidecB type. In the arrangement and the peculiar 

 venation of the leaves, Pycnohotrya very much resembles certain species of 

 Pleiocarpa and Polyadoa with wliich it has, however, not much in common 



in other respects. 



Leaves lanceolate, | to 1 in. broad; panicles leafy, 



many-flowered, up to 3 in. long . . . . 1. P. nitida. 



Leaves oblong to oblanceolate or obovate, |-1^ in. 



broad ; corymbs up to 1 in. long . . . 2. P. muUifiora.

 }-l in. broad, shining and glabrous above, paler, dull and dotted with 

 black glands, and minutely rusty-papillose on the midrib below ; 

 secondary nerves scarcely 1 lin. distant, with fainter parallel veins 

 between them ; petiole slender, 2-3 lin. long. Panicle very many- 

 flowered, compound, often leafy, finely rusty-tomentose all over;
