 2-5-celled ; ovules 1-4 in each cavity, anatropous, pendulous ; style short 

 or none ; stigma very small, or 2-3-lobed. Fruit dry, small, 1-5-seeded.

 acute, shorter than the petals. Petals 5, white, acute, spreading. Stamens 5, 

 opposite the sepals, the filaments subulate, the anthers oval. Ovary ovoid, sessile, 

 mostly 2-celled, sometimes 3-celled; ovules 2-4 in each cavity; style short, thick, 

 2-3-lobed. Fruit ovoid, 2-3 seeded, the pericarp spongy. [In honor of Domenico 

 Cyrillo, professor of medicine at Naples.] Two species, of southeastern N. Am. 



1. Cyrilla racemiflora Walt. Southern Leatherwood or Ironwood.

 6-25 mm. wide; racemes narrow, 5-15 cm. long, bearing the very numerous small 

 white flowers nearly to the base; pedicels 2-4 mm. long, somewhat longer than 

 the bracts, or shorter; fruit about 2 mm. long. Along streams and swamps, Va. to 

 !• 'la. and Tex. Also in the West Indies and S. Am. May -July.
