1886 (n. 251). Dr. Palmer’s specimen was referred by Dr. Gray 
(P. A. A., XXIT. 436) to D. stapelieflorus, since it accorded with 
Reichenbach’s exceedingly defective description. _ The additional 
notes and excellent plate of that species in Regel’s Gartenfloray 
Vol. VI., however, show clearly that it is altogether different, with 
larger, somewhat undulate leaves, much shallower corolla tube, and 
broader differently colored limb. Mr. Pringle’s specimen and one 
of Dr. Palmer’s show no tendency toward a climbing habit; but a 
detached branch with Dr. Palmer’s no, 251 has longer, flexuous 
internodes, suggestive of such a character. The flowers on this 
branch are larger, and the common peduncles longer. 
GONOLOBUS SUBERIFERUS. Stem covered’ with a thick rough 
light yellowish corky bark: branches, petioles, and peduncles cov- 
ered with a spreading pubescence: leaves ovate, acuminate, deeply 
cordate, with a narrow, often closed sinus, pubescent on both sur- 
faces and ciliate, 14-2 inches long, 1 inch broad: petioles an inch 
long: peduncles about half as long, each bearing a single pedicel 
an inch in length: calyx segments ovate-oblong, acute, pubescent 
and finely granular on the outer surface, ciliate, nearly smooth 
within, corolla 1} inches in diameter; segments ovate, obtuse, 
yellowish green, very minutely granular, otherwise smooth, exceed- 
ing the calyx by half, not conspicuously marked or veined: top of 
column white: crown dark brown: follicles slender, smooth, more 
than 3 inches in length, the calyx persistent at its base. — San 
José Pass, San Luis Potosi, July, 1890 (n. 3631). fe 
PHACELIA NAMATosTYLA. A small, slightly fleshy annual: 
stems numerous, short, 2-3 inches in length, prostrate, branching, 
pubescent: leaves bipinnatifid, 8-12 lines in length; pinne about 
seven pairs and terminal one, oblong, obtusely lobed, covered above 
with a fine gray pubescence, smoothish below, except the. midrib; 
margins strongly revolute: racemes numerous, dense, not exceeding 
the leaves; bracts minute or obsolete; flowers very small: calyx 
lobes oblong-spatulate, corolla white, a line in length, campanulate 
with slightly spreadin g limb of five rounded lobes: stamens inserted 
upon the lower part of the tube, scarcely equalling the corolla; fila- 
ments smooth: style divided nearly to the base; summit of the 
ovary pubescent; ovules two on each placenta, pendent; capsule 
globose, shallowly sulcate in the middle of each of the two valves; 
seeds dark brown, one line in length, conspicuously pitted. — Car- 
neros Pass, Coahuila, May, 1890 (n. 3493). This species is anoma- a 
lous in its style, which is divided practically to the base, as 1D
