finely and densely pubescent ; cortex pealing off below; branches 
rather short, very slender, alternate, ascending: leaves opposite, 
glabrous, mostly erect, essentially entire, oblong, obtuse or roundish 
at the apex, obliquely cordate at the base, short-petioled, 3 to 6 
lines long, half as broad, somewhat pellucid in the interstices of 
the veins; stipules minute, lanceolate, somewhat fringed : invo- 
lucres alternately fascicled in the upper axils, on very short pedi- 
cels, very small, one-third line long; glands 4, unappendaged, not 
dark-colored: capsule ovate; cells finely crested upon their rather 
sharp dorsal keels, half line long; the three styles short, bifid; 
seeds yellowish-brown, finely sculptured.—Collected on Char es 
Island, June, 1891. A species with the habit of Z flabellaris 
Ands., but more slender: leaves mostly smaller, stem and fruit 
Aga glands smaller and not dark-colored, and styles much 
shorter, 
EvrsorsraA NumMuLartA Hook. fil. var. GLaBra. Glabrous 
throughout and somewhat glaucous: leaves nearly all unequally 
2-lobed with an oblique sinus between the lobes: seeds slightly 
longer and a little more decidedly angled than in the type.—Col- 
lected at Cuevas Bay, Charles Island, July, 1891. 
AcatypHa Bavrit. Herbaceous: stem and _ petioles densely 
ubescent-tomentose : leaves ovate, short-acuminate, rather reg 
arly and somewhat doubly crenate-dentate, appressed-pubescent 
upon both surfaces, especially upon the veins beneath, 1} to 3 
inches long, two-thirds as broad, 5-nerved from the truncate OF 
subcordate base; petioles ascending, 1 to 2 inches long; stipules 
small, subulate-setaceous: spikes axillary, slender, 24 inches 1» 
length, androgynous; pistillate involucres commonly solitary, 
2-flowered, sessile near the base of the spike, the slender 8 
nate portion of the spike about a line in diameter, flexuous, ee 
flowered below; rhachis densely grayish pubescent: bracts of t r

AristmpA vittosa, Annual: root a cluster of short delicate 
fibres: culms several, slender, ascending, nearly a foot in height; 
internodes minutely puberulent under a lens: blade of leaves th 
flat, narrowly linear, 2 to 5 inches long, 1 to 1} lines br 1 at 
ad-
