BOTANY. 
CLEIsroGAMous FLowers oF Danruonia.—I have been much 
interested in the article in the April number of the NATURALIST, 
by ringle, on the Cleistogamous Flowers of Danthonia. 
D. spicata is very common in all our dry, sterile, or rocky 
woods; occasionally some bunches occur in moist ground, and 
these can readily be pulled out by the roots, with no disposi- 
tion to separate at the lower joints; but when the plant grows in 
dry ground, as it usually does, the culms separate near the root 
without much difficulty. This I have. always considered was due 
region of New Jer. ersey, growing in little tufts; in that respect 
somewhat different in habit from D. spicata. Last June whilst 
botanizing near Egg Harbor City, in this State, I found a large 
number of these tufts, each having from 6 to 20 culms, and sO 
brittle or readily disarticulating at the lower joints, that it was 
with great difficulty that I could secure a decent specimen; On 
endeavoring to pull up the plant, in every instance the separation 
occurred ; the only way to succeed was to dig out the roots with- 
out touching the stem at all, and even then the effort to shake oi 
the loose sand, often caused the culm to break away. sua 
specimens of D. spicata very frequently have a few flowers in the 
axils, but I have never seen any in D. sericea—Jsaac C. Martin-
