branched from the base, .6-1.5 dm. tall; leaves narrowly 
obovate below, almost linear above, .5—2 cm. long; .1—.4 cm. 
broad, sessile, with conspicuous articulations at the junctions 
with the ocree, acute at the apex, acuminate at the base, 
strongly revolute, much the same length even to the summit 
of the stem; mid-rib very prominent beneath and generally 
wing-like; ocreze funnel-form, lacerate to about the middle; in- 
florescence of axillary clusters extending to the very base of 
the stem, and bearing from one to four flowers; flowers rather 
large; calyx five-parted, green, only slightly lighter on the 
borders; style very short, three-parted, the divisions hardly 
perceptible; achene triquetrous, oblong, rather blunt at both 
ends, smooth and very glossy. 
-A well marked species of the Avicularia section collected by 
Brandegee on the Sawatch Range, Colorado. The specimens are 
in the Herbarium of the California Academy of Sciences. 
POLYGONUM PUNCTATUM, EIl., var. ECILIATUM, n. var. More robust 
than the species, less scurfy throughout, erect, much branched; 
leaves lanceolate to oblong-lanceolate, rather broad, less punc- 
tate than the normal form; ocrez cylindric, loose, long, strictly 
entire and free from bristles; the narrow racemes, as well as 
the upper parts of the pedicels, dark reddish-purple; achene 
broadly oblong, finely but plainly reticulated. 
Differs from the species principally in its glossy appearance, 
owing to the absence of the usual scurfy surface, perfectly smooth 
and eciliate ocrez, and the slightly narrower and more reticulated 
achene. The color of the flowers and racemes, though of less 
consequence, is very striking. 
Collected by Mr. Pringle in wet places, Valley of Toluca in the 
State of Mexico. No. 4213. 
POLYGONUM PERSICARIOIDES, H.B. K. This sub-tropical species 
heretofore so imperfectly known, has been discovered in Lower 
California, by Mr. Brandegee, at two localities, namely, San Jose del 
Cabo and Sierra de San Francisquito. It ought to be found in 
Southern California and the States to the east. 
Mr. Pringle, in his last Mexican journey, encountered a pecu- 
liar form of this species. The stems are several from an oblique 
root-stalk, simple or nearly so, leaves shorter, broader and less 
acute than in the normal form, and the narrow racemes fewer 
flowered. The habitat is given as wet meadows, Valley of Toluca, 
State of Mexico, No. 4218.
