HxpEOMA NANA. H. dentata, var. nana, Torr. Bot. Mex. 
Bound. 130. H. thymoides, Gray, Syn. Fl. 302 in part, not 
of Persoon. The name H. thymoides, Gray, being revertible, 
I adopt as specific the above, for what appears to be the type 
of Gray’s species. 
HEDEOMA BLEPHARODONTA. Slender decumbent stems 6 
inches high, tufted on a ligneous caudex, leafy and floriferous 
throughout, the internodes short, the whole stem leafy- 
spicate; herbage green but sparingly pubescent: leaves 3 
or 4 lines long, oblong, entire: flowers few in the axils and 
small: calyx-tube scarcely gibbous, its ribs not hispid; 
ealyx-teeth very unequal, strongly though sparsely hispid- 
ciliate. 
Near Flagstaff, Arizona, Aug., 1884, M. E. Jones. Spec- 
imens in the U.S. Herbarium. 
. Lycopus AsPER. Stems stout, simple, 1 foot high or more, 
very leafy and with short internodes, the angles obtuse: 
leaves of firm texture, almost subcoriaceous, sessile, oblong- 
lanceolate, acute, very evenly and saliently serrate through- 
out, notably veiny, roughened on both faces by coarse 
gland-dots and short scabrous hairs: calyx-teeth large, 
ovate-lanceolate, acuminate, not spinose-tipped, scabrous- 
serrulate marginally: nutlets very short, smooth, outline 
of the back cuneate-obovate, the callous margin much broader 
at summit than in its extension down the sides. 
A most distinct sessile-leaved Lycopus, occurring in the 
Langlois Herbarium at the Catholic University, collected at 
Battle Lake, Minnesota, Aug., 1892, by Mr. E. P. Sheldon, 
and distributed as L. lucidus obtusifolius. The species is 
soboliferous, that is, propagating by wholly subterranean 
rhizomatous offshoots; these rather short and stout at the 
time the plants were gathered. 
. LxcoPus LACERUS. Stem rather slender and somewhat 
flexuous, 2 feet high, sharply angular and the angles
