78 PROCEEDINGS OF THE AMERICAN ACADEMY. 
BLETIA MACRISTHMOCHILA, Greenm., Proc. Am. Acad. xxxii, 297, 
Flowering and fruiting specimens of this attractive orchid were secured 
by Mr. C. G. Pringle during the past season, on banks of ravines near 
Guadalajara, Mexico, no. 8640 (hb. Gr.). From Mr. Pringle’s recently 
collected material it may be noted that the mature capsule is about 5 cm. 
in length and 1 em. in diameter. 
Celtis platycaulis. Fruticose : stems and branches flattened, cov- 
ered with a reddish-brown bark, bearing single, curved, 5 to 6 mm. 
long spines: leaves ovate to obovate, 3 to 5 cm. long, 1.5 to 3 cm. broad, 
acute to rounded at the apex, usually serrate from near or just above the 
middle to the apex, entire in the lower half, rarely entire from base to 
apex, 3-nerved, in the very young stages puberulent, but soon becoming 
glabrous or essentially so; petioles 4 to 5 mm. long, and as well as the 
ultimate branches puberulent: the cymose inflorescences of the male 
flowers twice or more exceeding the petioles: fertile flowers few, borne 
at the tips of the branches; ovary puberulent; style branches bifurcated: 
mature fruit not seen. — Mexico. State of Morelos: volcanic hills near 
Yantepec, altitude 1230 m., 5 July, 1901, C. G. Pringle, no. 8535 
(hb. Gr.). 
OxyBaPnus viscosus, L’Her., in Willd. Sp. i. 185; Choisy in DC. 
Prodr. xiii. 2, 430. Specimens collected by Mr. C. G. Pringle at Tehua- 
can, Mexico, 1901, no. 8600 (hb. Gr.), agree in all important characters 
with typical representatives of the above species. In Mr. Pringle’s 
specimens, however, the perigonium is considerably larger than is 
described and figured for O. viscosus, L’Her.; but this slight difference 
is supplemented by no other evident character, hence it seems best for 
the present at least to regard the Pringle plant as a mere form of the 
species here mentioned. 
Ribes Dugesii. A much-branched shrub: stem covered with red- 
dish-brown bark, glabrous; branchlets finely pubescent: leaves petiolate, 
ovate-rotund, shallowly 3-5-lobed, doubly crenate-serrate, 3-7-nerved 
from a cordate base, green and glabrous above, paler and somewhat 
glandular-pubescent beneath, especially on the prominent nerves; peti- 
oles 1 to 3 em. long, and as well as the inflorescence minutely puberulent 
with stipitate glands intermixed, dilated at the base into a more or less 
glandular-ciliate expansion: racemes pedunculate, borne at the ends of 
young terminal branches and lateral shoots, 3 to 6 cm. loug, suberect 
or somewhat drooping ; pedicels 1 to 10 mm. long, jointed above, naked or 
bibracteate at the joint: flowers 1 em. or less long: calyx subcampanu- 
__ late, white or more or less roseate, 5-lobed for about one-half its length ;
