A species with scabridly pubescent terete branches ; leaves oblong, subcordate, acu- 

 minate, scabrid above, with several glands at the base of the limb, velutinous beneath, 

 4 in. long, 1^ in. broad, on petioles 3 lines long ; raceme lateral, arcuate, 2-3 times 

 as long as the leaves, scabridly puberulous, bearing many almost sessile flowers, partly 

 concealed by as many bracts, which are oblong, mucronate, membranaceous, reddish, 

 6-8 lines long, 2-3 lines broad ; sepals acuminately ovate, 2 lines long, with an inner 

 dentate scale ; corolla scabridulous, red ; tube 1 in. long, a little narrowed in the middle ; 

 segments shorter than the tube ; stamens inserted in the constriction of the tube ; disk 

 urceolate, thick, a little shorter than the ovaries ; follicles arcuate, torulose, converging 

 at the apex, 6 in. long ; seeds 4 lines long, with a rather long reddish coma. 



This species is placed in Lasegwea on account of its general character, its inflores- 

 cence, and more especially the form of its disk ; it is evidently near the preceding 

 species.

A plant possessing all the characters of Laseguea : its branches are scabrescent ; the 

 leaves ovate or elHptic-ovate, roundish and shortly cordate at the base, shortly acuminate, 

 subscabrid above, pilose on the midrib above with hairs globular at their base, beneath 

 subsericeously pubescent, on very short petioles ; racemes axillary, cylindrical, densely 

 spicate, as long as the leaves, puberulous, furnished with many imbricating lanceolate 

 bracts as long as the pedicel and calyx ; pedicels short ; sepals linear, subequal, pube- 

 rulous, each with an inner obtuse or denticulate scale ; tube of corolla slender, pube-
