RUBIACEJE. 825 



The character of Hillia must be enlarged, if, as would be advisable, Cosmibuena, R. P., 

 Benth., is to be reduced to it. 



43. H. longiflora, Sw. Leaves elliptical, pointed; corolla-lobes 6 (-7), lanceolate, 

 bluntish, recurved, i-i as long as the tube, contorted -imbricative ; style as long as the co- 

 rolla-tube. — Jacq. Amer. Pict. t. 97; Sw. Obs. t. 5./. 1. — H. parasitica, Jacq. — A low- 

 shrub, rooting at the base ; leaves 2"-5", corolla-tube 4"-3", lobes l"-2" long, the latter 

 tapering from the imbricated base ; 2 exterior involucel-leaves oval-oblong, blunt, including 

 the calyx, 14"'-6'" long. — Hab. Jamaica!, Bancr., rare, in the higher mountains; Domi- 

 nica !, Imr., S. Vincent !, Guild. ; Trinidad !, Or. ; [Cuba !, French islands ! ; Mexico to New 

 Granada!]. 



44. H. tetrandra, Sw. Leaves obovate or spathulate-lanceolate, cuneate at the base, 

 rounded at the top; corolla-lobes 4, ob ovate-roundish, one-third or one-fouithaslong as the 

 tube, 2 exterior ; style half as long as the corolla-tube. — 3'-4' high : roots bearing small 

 tubers; leaves 2"-U", corolla-tube 1£"-1", lobes 8"'-4'", linear-capsule 2"-3" long; seeds 

 1"', their hair-tuft 6'" long. — Hab. Jamaica !, Mac/., Wils., common on the higher moun- 

 tains, among rocks and tree-roots; [Cuba!]. 



21. WARSZEWICZIA, Kl. 



Calyx-limb 5-lobed : one lobe in the corymb transformed into a petioled, large, coloured 

 leaf. Corolla small, infundibular : lobes 5, imbricative. Stamens exserted, inserted into 

 the corolla-throat : anthers incumbent. Stigma 2-lobed. Capsule septicide : seeds fusi- 

 form, not winged. — Large-leaved trees ; corymbs contracted, arranged in a long, nodding, 

 racemiform panicle. 



45. W. coccinea, Kl. {ex syn.). Leaves obovate-oblong, pointed, hispidulous chiefly 

 on the nerves beneath ; transformed calyx-lobes oval, blunt at the top, shortly tapering at 

 the base, reticulated, scarlet, as long as their petioles. — Vahl, Symb. 2. t. 29. — Macrocnemuro, 

 V. Calycophyllum, DC. W. Schomburgkiana, Kl. — Leaves l'-l$' long, 6" broad ; trans- 

 formed calyx-lobes 3" long, \\"-\%" broad.— Hab. Trinidad !, Lockh., Sieb. Tr. 37 ; 

 [Mexico! to equatorial Brazil! and Peru!]. 



22. ARACHNOTHRIX, Planch. 



Calyx-limb 4-partite. Corolla salver-shaped, devoid of an annular production at the 

 throat : lobes 4, roundish, imbricative. Stamens included, inserted into the corolla-tube : 

 anthers subsessile. Stigma 2(-3)-fid. Capsule septicide : valves at length often 2-fid : 

 seeds minute, wingless. — Shrubs : the younger parts bearing an arachnoid down ; cymes ' 

 terminal : flowers serial on the inner side of their branches. 



The septicide capsule is the chief character of this genus, in contradistinction to Ronde- 

 letia : hence R. leucophylla, Kth., is to be excluded, whife R. elongata, Bartl. !, is an 

 Arachnolhrix. 



46. A. hispidulus, Gr. (n. sp.). Leaves elliptical, pointed, arachnoid-puberulous and 

 ylabrate above, hispidulous on the nerves and veins beneath : stipules subulate-lanceolate, as 

 long as the petioles ; peduncles of the cyme single, as long as the leaves ; calyx-lobes un- 

 equal, lanceolate, the longest thrice exceeded by the slender, villous corolla-tube ; style in- 

 cluded. — Nearly allied to A. elongata, PL, which has the leaves arachnoid-villous beneath, 

 and the style exserted. Leaves 3" long, 1" broad; corolla-tube glabrous within, twice as 

 long as the linear anthers, 6'", lobes 1'" long ; stigma-lobes lanceolate. — Hab. Trinidad !, 

 Cr., at Maraccas waterfall. 



23. RONDELETIA, L. 



(Petesia, P. Br. Stevensia, Poll.) 



Calyx-limb 5-4-partite. Corolla salver-shaped, rarely rotate, produced into a callous 



ring at the throat : lobes 5-4, roundish, imbricative. Stamens included, rarely semiexserted, 



inserted into the corolla-tube. Stigma 2-fid or emarginate. Capsule loculicide, subglobose : 



Ti»rve» often at length 2-fid : seeds minute. — Shrubs, rarely trees ; flowers in paniculate or
