GREENMAN. — MEXICAN PLANTS. 305 
slender, filiform, exceeding the corolla; stigma 2-parted: capsule subglo- 
bose, somewhat compressed laterally, 8 to 9 mm. long, equally broad, and 
6 to 7 mm. thick. — Collected by C. G. Pringle, on a mountain side near 
Cuernavaca, State of Morelos, 18 November, 1895, no. 7062, and in the 
same locality in 1896, no. 6330. The above plant is in all probability 
the one described in HBK. Nov. Gen. & Spee. iii. 385, notwithstand- 
ing the little discrepancy as to the number of leaves in the whorl, and 
the quadrangular stem ; the former character is a variable one, as shown 
by many species of the genus, and the angulation of the stem depends to 
a great extent upon the number of leaves in the whorl. It seems best, 
therefore, in view of the very meagre description of the above species, 
which was doubtless drawn from a very incomplete specimen, to regard 
the above cited numbers of Mr. Pringle as representing the Bouvardia 
obovata, HBK., and to amplify the characters of the same. 
HaMeLia noposa, Mart. & Gal. Specimens agreeing in all essen- 
tial characters with Walper’s description of the above species (Walp. 
Rep. vi. 51) were collected by Rev. Lucius C. Smith at Ojitlan, Oaxaca, 
altitude 198 m., 21 August, 1895, no. 605. The plant differs, however, 
in having the fruit elliptic-oblong (6 to 9 mm. long, one half as broad) 
Instead of globose. 
Crusea calcicola. An herbaceous annual: stems erect, branching 
from the base, tetragonal, glabrous or hispidulous on the angles: leaves 
lanceolate or lance-oblong, 2 to 44 cm. long, 6 to 13 em. broad, acute, 
somewhat narrowed at the base, margin revolute, scabrous, midrib and 
velus prominent beneath, glabrous on either surface, slightly paler be- 
heath ; stipules puberulent, 3 to 4 mm. long bearing 3 to 7 sete on either 
Side: inflorescence in axillary or terminal pedunculate involucrate heads : 
peduncles above puberulent and often hispidulous on the angles: floral 
leaves (subtending the heads) 1 to 2 cm. long, ciliated at the broadened 
ase: bracts strongly dilated at the base, short-acuminate, shorter than 
the floral leaves: flowers short-pedicellate, intermixed with numerous 
laciniate pales : calyx small, about 2 mm. long, 4-lobed ; lobes slightly 
exceeding the tube, narrow, acute, long-ciliate: corolla tubular, narrowed 
below, somewhat ampliated above, 4-lobed, about 4 mm. long, white; 
lobes oblong, obtuse, usually bearing on the outer surface near the apex 
a few spreading hairs: stamens exserted : stigma overtopping the anthers. 
~ Collected by C. G. Pringle, on dry calcareous hills, Las Sedas, Oaxaca, 
at an elevation of 1,800 m., 8 September, 1894, no. 4869. Distributed 
as Q, cruciata, Wats., but differing from the latter species in the char- 
acter of the stem, the stipules, and the bracts.
