linear, nearly equalling the tube of the corolla; the latter appar- 
ently yellowish, 4—5 lines in length, with small only slightly 
spreading limb: style exserted; nutlets small, shining, white or 
discolored, scarcely keeled. — Alkaline meadows, Hacienda de An- 
gostura, San Luis Potosi, July, 1891 (n. 3802). Distributed as a 
form of L. strictum, Lehm., equalling Schaffner’s no. 728. A more 
careful examination shows that it is not very near Schaffner’s doubt- 
ful plant, and is certainly distinct from Z. strictum, which has 
linear acute leaves, narrow bracts, and keeled nutlets. Mr. Prin- 
gle’s no, 3245, distributed last year as L. strictum, probably also 
represents a new species. It is much more robust than L. strictum, 
and has a fusiform root more than half an inch in thickness. 
IpomM@A ORNITHOPODA. Glabrous, stem slender, twining, an- 
gulate, dark colored: leaves very deeply palmately or rather sub- 
pinnately 5—7 parted; lobes linear, 1}—2 inches long, 1-2 lines broad, 
obtuse, apicuiate, eutire or wavy; the edges revolute; petioles 6-8 
lines long: peduncles springing from most of the axils, but many 
of them abortive; the developed ones 2-3 inches long, one-flowered; 
pedicels } inch long, somewhat thickened upward: sepals orbicular, 
thin, 5-6 lines in diameter, rounded or even retuse at the summit, 
purplish on the margins: tube of the corolla very short, included 
in the calyx, limb 14-2 inches in diameter, with a broad open 
throat, appressed-villous on the outer surface, color uncertain: fruit 
not seen. — Hills, Canoas, San Luis Potosi, July, 1890 (n. 3553.) 
GERARDIA PuNcTATA, Rob. (P. A. A., XX VI. 172). Additional 
Specimens of this plant, collected at Carneros Pass, Coahuila 
(n. 3682), and Las Canoas, San Luis Potosi (n. 3938), show that it 
is probably perennial. The corolla sometimes attains a length of 
16 lines. The name was unfortunately chosen, since the punctate 
character of the calyx appears to be exceptional, and perhaps due 
to the presence of afungus. Notwithstanding its seemingly peren- 
nial nature and longer flowers, this species may prove to be the 
G. dasyantha, Cham. & Schl., insufficiently characterized in 
Linnea, V. 104, and DC. Prod., X. 517. . 
BELOPORONE FRAGILIS. Stem 3-5 feet high, somewhat branched, 
smooth, scarcely striate, strongly contracted above the nodes and 
readily disarticulating in a dried state; the transverse lines con- ; 
necting the bases of the petioles often bearing a tuft of hairs, — 
especially in the younger parts of the plant: leaves ovate, acumi- 
nate, blunt at the apex, obtuse or rounded at the base, 14-3 inches 
long, nearly half as broad, minutely mussel: — — —
