form, unequally two-celled, splitting only on the posterior 

 side. Seeds few, not reticulate. Bracts not colored. 

 Corolla yellow or pink throughout, the anterior lip not 

 raised into a palate. Anthers glabrous. Seeds matur- 

 ing more than four to a capsule. Sepals of each 

 side united nearly or quite to apex. Leaves bipin- 

 natifid-lobed. 37. Pedicular is. 



Corolla white, the anterior lip raised into a yellow densely 

 pubescent palate. Anthers pubescent. Seeds matur- 

 ing two to four to a capsule. Sepals united at base 

 only, the two postero -laterals longer. Leaves lanceo- 

 late, entire or setaceous-toothed near base.

Capraria biflora L., 1. c. 628. 1753. "Habitat in Curassao." Specimens 

 from Curagao seen in Herb. New York Botanical Garden. 



Sandy soil, mostly along the beach, somewhat in waste 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
