lastoma laniflorum, D. Don, in mem. vvern. soc. 4. p. 292. 

 Flowers about 3 together in each axil, yellow ? Petals obovate- 

 oblong. Stamens 10, one-half shorter than the petals. Anthers 

 ovate, obtuse, ending in short beaks. The specific name is 

 derived from Xu^^'C, a lamp ; in reference to the cottony ap- 

 pearance of the wool on the plant resembling wicks. 



Lamp Trembleya. Shrub 1 to 2 feet. 



Cult. For culture and propagation see Marcetia, p. 749.

 /jorpvc, bolrys, a raceme ; in reference to the flowers not being 

 sufficiently known). D. C. prod. 3. p. 127. 



LIN. SYST. Decandria, Monogynia. Calyx free, somewhat 

 campanulate, with 5 short blunt teeth. Petals 5, oval. Stamens

 Ovarium and style unknown. Capsule bursting by 5 parts, 

 with the central column at length free from the valves. Seeds 

 unknown. A climbing shrub with terete branches. Leaves 

 clothed with rufous villi on both surfaces when young, but in 

 the adult state glabrous, except the nerves, petiolate, ovate- 

 cordate, acuminated, ciliately serrated, 5-nerved. Flowers white,

 characters). D. C. prod. 3. p. 127. Anthers opening by 1 

 pore at the apex. Ovarium sometimes free, and sometimes 

 adnate to the calyx, crowned by scales or bristles at the apex.

LIN. SYST. Decdndria, Monogynia. Tube of calyx ovate ; 

 lobes 5, narrow, acuminated. Petals 5, obovate. Stamens 10 ; 

 filaments pilose ; anthers elongated, terminating in short beaks, 

 having their connectives tumid and biauriculate at the base. 

 Ovarium setose at the apex, probably somewhat adnate to 

 the calyx in the young state. Style usually pilose. Capsule 

 dry, 5-celled. Seeds few, cochleate, rather angular, with a 

 somewhat orbicular, basilar hylum. Shrubs, natives of South 

 America. Branches clothed with adpressed bristles. Leaves 

 on short petioles or sessile, 3-5-nerved, quite entire, ciliated, 

 bristly on the upper surface ; the bristles adpressed, and usually 

 regularly directed from the middle to the nerves ; villous or 

 setose on the nerves beneath, and velvety or villous between 

 the nerves. Flowers large, purple, disposed in terminal ra- 

 cemes or panicles ; before expansion hidden by 2 bracteas 

 each, which fall off as the flower expands. The species have 

 the habit of Pleroma, but differ in the genitals being hispid, and 

 in the capsule being dry and free, not baccate and adnate to the 

 calyx.
