Myrica PUMILA (Michx.). 
Myrica cerifera var. pumila Michx. F]. Bor. Am. 2: 228. 1803. 
It seems strange that this so-called variety of Myrica cerifera 
has never before been given specific rank. 
CASTANEA NANA Muhl. Cat. 86. 1813. 
Mr. Kearney has recently given us an excellent description* of 
this characteristic chinquapin. He omitted, however, the most 
striking character of the species. During last July and August I 
had an opportunity to observe C. zana at various points in south- 
eastern Georgia, where it is plentiful and distributed in large 
patches over the hot sandy wastes. In its relatives, Castanea den- 
tata and C. pumila, we find typical trunks.or main stems developed 
above ground, but in the case of C. zava the main stem never 
rises to the surface of the soil, but grows along at the depth of one 
or several inches beneath the surface, sending up lateral branches 
at intervals. A comparative study of the anatomy of this stem 
would doubtless prove interesting.

Last July I collected good fruiting specimens of this plant 
along the Flint River, below Albany, Ga. The species is readily 
separable from the related A. Serpentaria by its more deeply lobed 
capsule, which is just about one-half as long. Mr. A. H. Curtiss 
has sent me specimens which he gathered in northeastern Florida 
several years ago. 
PORTULACA CORONATA N. sp. 
Rather stout, succulent, glabrous and somewhat shining, the 
roots fibrous, descending and freely branching; stem simple and 
erect, or diffusely branched from I or 2 cm, above the root, nearly 
terete, its branches spreading and ascending, bright flesh-colored 
or magenta, rarely lead-colored, the branches usually alternate, 
sometimes almost opposite, conspicuously articulated with the stem, 
the ends clavate and more or less tinged with green ; leaves sessile 
or nearly so, the lower ones usually oblanceolate, the upper 
ones oblong or oblong-lanceolate, alternate, except a whorl of 
from three to eight at the ends of the branches, flat, obtuse or 
rarely acutish, conspicuously articulated with the stem, somewhat 
fugacious, bright green, inconspicuously ciliolate with depressed
