Btichnera. didynamia angiospermia. 31 



of the size of a filbert. Ahljoiioh I have examined it in all 

 Stages*, yet I have never been able to fix upon any deter- 

 mined internal structure; there are a number of convoluted 

 lamina throughout, between these are lodged innumerable, 

 most minute seeds, like those of the Orchidece. 



BUCHNERA. Schreb. gen. N. 1035. 

 Calyx five-cleft. Tube of the corol long; border from 

 four to five-cleft, unequal. Capsule two-celled, two-valved; 

 seeds numerous. 



3. B. asiatica. Willd. 337. 



Erect, annual, four-sided. Leaves sessile, opposite, and 

 alternate, linear, scabrous, entire. Segments of the lower lip 

 olthe corol oval, and rather acute. 



Kalu polapen. Rheed. Mai. ix. t. G6. 



A small erect annual, a native of pasture ground, or such 

 as has been lately in culture, appearing and flowering during 

 the wet season. 



Stem erect, from six to eighteen inches high, four-sided, 

 scabrous. Branches one or two pairs, opposite. Leaves ses- 

 sile ; below opposite, above alternate, linear, erect, after- 

 wards a little recurved, scabrous, about an inch long- and one- 

 eighth broad, those towards the extremities are very small, 

 which makes them (the extremities) more like long- spikes, 

 than the extremities of the branches, /^lowers axillary, soli- 

 tary, sessile, of a middlhig size, white. Branches two, press- 

 ing on the calyx, laterally lanceolate. Calyx five-parted, 

 striated, scabrous. Corol ; tube rather longer than the calyx, 

 curved at the apex ; the border flat, two-lipped; upper lip 

 broad, emarginate ; the under one three-parted. Capsiile co- 

 vered by the calyx, opening at the apex; receptacle co- 

 lumnar. 



There is a variety with exceedingly bright red flowers. 

 Cattle do not like them.
