GREENMAN. — MEXICAN PLANTS. 305 



slender, filiform, exceeding the corolla ; stigma 2-2:)arted : capsule subglo- 

 bose, somewhat compressed laterally, 8 to 9 mm, long, equally broad, and 

 G to 7 mm, thick, — Collected by C. G, Pringle, on a mountain side near 

 Cuernavaca, State of Morelos, 18 November, 1895, no. 70G2, and in the 

 same locality in 1896, no, 6330, The above plant is in all probability 

 the one described in HBK. Nov. Gen. & Spec, 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 nodosa, Mart. & Gal. Specimens agreeing in all essen- 

 tial characters with "W^alper's description of the above species (Walp. 

 Eep. 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. 



Crnsea, calcicola. An herbaceous annual : stems erect, branchinor 

 from the base, tetragonal, glabrous or hispidulous on the angles : leaves 

 lanceolate or lance-oblong, 2 to 4|- cm. long, 6 to 13 cm. broad, acute, 

 somewhat narrowed at the base, margin revolute, scabrous, midrib and 

 veins prominent beneath, glabrous on either surface, slightly paler be- 

 neath ; stipules puberulent, 3 to 4 mm, long bearing 3 to 7 setas 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 

 base : 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 : corojla 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 C. cruciata, "Wats,, but differing from the latter species in the char- 

 acter of the stem, the stipules, and the bracts,
