29. Pycnorhachis, Benth. 



A hairy twining vindershrub. Leaves opposite. Flowers in refiexed 

 pairs, spirally disposed round the long fleshy branches of an axillary 

 racemiform cyme. Calyx 5-partite ; scales 5 to 10. Corolla turbinate, 

 with short tube, deepW 5-fid ; lobes valvate, slightly twisted to the left. 

 Coro?ia-scales 5, spreading at the base of the staminal- column opposite 

 the anthers. Staminal-column short, adnate to the middle of the 

 corolla-tube ; anthers erect, with membranous, hyaline appendages ; 

 pollen-masses 1 in each cell, long, slender, cylindric, waxy, erect, 

 attached by short caudicles to the pollen-carriers. Ovary of 2 carpels, 

 sunk in the calyx-tube ; style-apex 5-angled, obtusely conical, much

 Branches flexuose, hispid with spreading tawny hairs. Leaves oblong- 

 obovate, abruptly cuspidate-acuminate at apex, narrowly cordate at

 on the nerves; 4 to 6 in. long, 1-5 to 2 in. broad; midrib prominent 

 beneath ; main nerves 10 to 12 pairs, curving upwards and joined by 

 prominent transverse reticulations ; petiole "25 to "5 in. long, villous. 

 Cymes 3 to 6 in. long; peduncle 1 to 2 in. long, thick; branches usually 

 1 to 8, -3 in. in diam. minutely pubescent flower-pairs on rounded 

 tubercles ; pedicels short ; buds conical, long-acuminate. Calyx minutely 

 red-hairy without, glabrous within ; lobes linear-lanceolate, "1 in. long. 

 Corolla deep purple ; tube very short, thickened, with a fringed annulus ; 

 lobes about '25 in. long, subulate-lanceolate from a broad base. Corona 

 of 5 thickened fleshy obtuse processes on the backs of the anthers. 

 Staminal-column short; appendages long, subulate, hyaline; pollen- 

 masses clavate, slender, attached by minute caudicles to the bases of

Malacca : Maingay (K.D.) 1141. 



The description, like that of Fl. Br. Ind., is chiefly taken from the full notes 

 given in Maingay MS. Vol. IV. 64. 



Tribe V. — Ceeopegie^. 



Stamens with their filaments connate into a tube, and adnate to the 

 style-apex at the top. Anthers erect or incumbent over the style-apex, 

 with or without appendages. Pollen-contents of each anther-cell 

 united in a waxy mass ; pollen-masses pellucid on the margin or at
