190 CYRILLACEAE. 
Cyritta. White ti ti. 
(Family Cyrillaceae). 
Shrubs or small trees: decidu- 
ous or subevergreen. Twigs rath- 
er slender and 3-sided: pith small, 
somewhat 3-sided, continuous. 
Buds small, sessile, several super- 
posed in an axillary groove, with 
a few pointed scales. Leaf-scars 
alternate, low, shield-shaped with 
acute lateral angles, fringed at 
top: bundle-trace 1, rather large 
and curved: stipule-scars lacking. 
Leaves when present rather thin, 
very hairy, entire, petioled. 
In addition to the two barely 
differentiable cyrillas of the 
southern United States, another 
occurs in the West Indies and 
still another in Brazil. Even these 
are so similar to our northern 
species that for some botanists 
they constitute only varieties of it. 
Twigs straw-colored, glabrous: leaves glabrous, green. 
Some leaves 10 cm. long. C. racemifiora. 
Leaves under 5 cm. long. C. parvifolia.
