Curacao seen in Herb. New York Botanical 
Sandy soil, mostly along the beach, ante in aut ground 
and on edges of hammocks inland, subtropical Florida. A wide- 
spread species of lowland Tropical America. Very variable; varies 
with us mainly in size and proportions of leaf, and in the length of 
the hairs on the stem and pedicels, such hairs in the plant consid- 
ered to be typical are entirely wanting. The pubescent state may 
be called forma hirta Loes., in Bull. Herb. Boiss., ser. II, 3: 284.

Flowering and fruiting probably throughout the year, although 
all specimens seen were collected between November and June. 
Corolla white or violet-tinged and slightly spotted with violet within 
throat. Normally the five stamens are fertile, but any, and as 
many as four, may become rudimentary. Examination of fresh 
flowers shows that both in Capraria and Scoparia the posterior 
lobes of the corolla are external in the bud, thus confirming the
