The genus Hyptis, consisting of above two hundred species from the warmer 
regions of America, and more especially from the Brazilian territories, is remark- 
able as well from the great diversity of habit, foliage, inflorescence, and calyx 
observable in different species, as by the constancy of the essential characters 
derived from the corolla and stamens. But amongst all the various forms 
hitherto observed, the present species is at once distinguished by the long thick 
snow-white wool which envelopes the flowers, whilst the rest of the plant is per- 
fectly smooth. Its nearest affinity is perhaps with H. tomentosa, Poit., but it 
differs so much in aspect, even from that one, that, without examining the corolla, 
one would hardly place it in the same genus.
