MEMOIRS OF THE KEW YOP.K BOTANICAL GARDEN 



Melastomataceae 



TiBOucHiNA membranifolia Cogii. BiiU. Torrey Clnl) 23 : 17. 

 1896. 



This species, heretofore known only in flower, appears to 

 have been collected in mature fruit at Canamina, 4,000 feet, 0. 

 E. White, July 20, 1921 (no. 278). In characters of stem, leaf 

 and indumentum, the specimens are indistinguishable from the 

 type, but they show a notable development in the fruiting inflo- 

 rescence. The peduncles are elongated to 5 and 6 cm., with cor- 

 resi)onding elongation of their branches, while some of the 

 l^edicels are 1 cm. long. The following is a description of the 

 fruits. 



Calyx-tube about 7 imn. long, 4 mm. wide, campanulate, with 

 the mouth slightly contracted, light-brown, strongly 10-ribbed, 

 the ribs broad and obtuse. Limb short, the teeth about a third 

 as long as the tube, triangular, acute, erect-spreading. 



Brachyotum setosum Glcason 



Stem suffruticose or herbaceous, 15-60 cm. high, freely 

 branched, minutely sordid-setulose and hirsute at the nodes 

 when young, glabrous with age ; petioles slender, 3-5 mm. long, 

 closely and minutely appressed-setulose ; leaf-blades thick and 

 firm, ovate-elliptic, 12-25 mm. long by half as wide, rounded at 

 both ends, entire, sometimes slightly revolute, 3-nerved, above 

 with 4 longitudinal bands of sparse, stout, appressed, yellow, 

 conic-subulate setae 0.7-1 mm. long and 0.1-0.2 mm. in diameter, 

 otherwise glabrous, beneath yellow-green, sparsely and finely 

 setulose on the veins ; flowers solitary or in threes, 5-merous ; 

 pedicels stout, 1 cm. long, jointed at the middle, densely ap- 

 pressed-setulose ; hypanthium reddish, broadly campanulate, 6 

 mm. long, closely and finely appressed-setulose with hairs 0.2- 

 0.3 mm. long ; sepals deltoid, 4 mm. long and wide, contiguous at 

 the base, abruptly narrowed from below the middle to an acumi- 

 nate apex, strongly thickened and densely setulose along the 

 center, the lateral basal margins thin, pale, membranous, gla- 

 brous, and setulose-ciliate ; petals purj^le, broadly ovate-rotund, 

 12 mm. long and broad, inequilateral, ol)tuse, minutely cili- 

 ate, somewhat fleshy, reticulate-veined; anthers linear-oblong, 

 straight, 5 mm. long, 1.4 mm. wide, the 2 basal appendages short, 

 ovate, blunt, 0.3 mm. long; ovary ovoid, strongly 10-ribbed, 5
