Trees or shrubs, with rigid unarmed terete branches. Leaves mostly opposite, entire, coriaceous, 
short-petioled, reticulate-veined, persistent ; stipules minute, caducous. Flowers yellow-green, minute, 
in small axillary sessile umbels from scaly buds. Pedicels stout, bibracteate near the base, two or three 
times longer than the flower. Calyx persistent, hemispherical, with deltoid acuminate spreading peta- 
loid lobes, the short tube filled with the fleshy disk. Stamens five, inserted on the margin of the disk, 
alternate with and rather shorter than the lobes of the calyx; filaments subulate, filiform, incurved ; 
anthers oval, attached on the back below the middle, introrse, two-celled, the contiguous cells opening 
longitudinally. Ovary free from the disk, almost superior, conical, contracted into a short erect thick 
style; stigma two or three-lobed ; ovules solitary, erect, anatropous; raphe ventral; micropyle inferior. 
Fruit ovoid, supported on the enlarged and now nearly entire calyx, and crowned with the remnants 
of the persistent style; sarcocarp thin, fleshy ; endocarp crustaceo-membranaceous. Seed solitary by 
abortion, erect, ovoid, or subglobose ; testa very thin, conspicuously rugose and tuberculated ; albumen 
copious, subcorneous, ruminate. Embryo axile; cotyledons oblong; radicle long, inferior, next the 
hilum." 
The genus Reynosia is West Indian. Three species are now recognized: Reynosia latifolia, a 
small tree, extends north to the shores of southern Florida and to the Bahama Islands; the others are 
little known shrubs of Cuba, Ste. Croix, the Virgin group, and probably of other islands.

cucullate unguiculate petals inserted on the margin of the disk 
between the lobes of the calyx. I have been able to examine the 
flowers of R. latifolia only ; these show no trace of petals. 
Reynosia was referred by Baillon (Hist. Pl. J. c.) to Condalia, 
from which it differs in the thinner and less prominent disk of the 
flower, the thinner wall of the stone of the fruit, the longer radi- 
cle, and the ruminate albumen. 
in Paris, where he received a first prize from the Académie des 
Sciences for his experiments with chloroform, and later the degree 
of Doctor of Science. He is known by the machine invented by 
him for increasing the yield of sugar from Sugar-cane, and by many 
publications upon chemical and agricultural subjects.
