I. NEW SPECIES OF SENECIO AND SCHOENOCAULON 
FROM MEXICO. 
By J. M. GREENMAN. 
Schoenocaulon calcicola Greenman, n. sp., bulbis ovoideis 1.5-2 
cm. diametro ; caudice erecto cylindrato 5-10 cm. longo a reliquis atro- 
brunneis vel nigrescentibus fibrosis squamarum foliorumque exterio- 
rum circumdato; foliis lineari-attenuatis 3-10 dm. longis 2-5 mm. 
latis 7-13-nerviis utrinque laevibus margine paulo hirtellis ; scapo 
nudo 5.5-7.5 dm. alto aliquanto flexuoso subancipiti glabro basin 
versus purpureo ; inflorescentia laxiflora 1-2 dm. longa 8-10 mm. an- 
thesi diametro ; bracteis parvis late ovatis tenuibus brunnescentibus ; 
floribus sessilibus vel breviter pedicellatis ; perianthio 6-partito, seg- 
mentis linearibus 2.5-3 mm. longis acutiusculis saepissime basi 
bidentatis ; staminibus perianthio longioribus; capsulis maturis ob- 
longo-lanceolatis ca. 1 cm. longis glabris reflexis.— Hillsides, Las 
Sedas, Oaxaca, Mexico, alt. 1830 m. 1 August, 1894, C. G. Pringle, 
no. 5754 (type, in hb. Gray); calcareous banks, Las Sedas, alt. 1830 m., 
19 July, 1897, C. G. Pringle, no. 6740 (hb. Gray, hb. Field Mus.). 
The latter number was distributed as S. intermedium Baker, a species 
from which S. calcicola is readily separated by its reflexed fruit. 
Schoenocaulon caricifolium Greenman, n. comb. Veratrum cari- 
cifolium Schlecht. Ind. Sem. Hort. Hal. 8 (1838). Asagraea carici- 
folia Kunth, Enum. Pl. iv. 666 (1843). Although this species has 
been treated by several authors as conspecific with Schoenocaulon 
officinale Gray, yet an examination of some of the original material, 
collected by Ehrenberg, of which there is now a specimen in the Gray 
Herbarium, shows very clearly that it can scarcely be regarded as iden- 
tical with Dr. Gray’s species. S. caricifolium differs from S. officinale 
in having narrower leaves, shorter scapes and inflorescence, and rela- 
tively shorter and distinctly inflated capsules. — Mexico, without defi-
