I. NEW SPECIES OF SENECIO AND SCHOENOCAULON 



FROM MEXICO. 



By J. M. Gkeesman. 



Schoenocaulon calcicola Greemnan, 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 -attenuates 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 fiexuoso subancipiti glabro basin 

 versus purpureo ; inliorescentia laxitlora 1-2 dm. longa 8-10 mm. an- 

 thesi diametro ; bracteis parvis late ovatis tenuibus brunnescentibus ; 

 fioribus sessilibus vel breviter pedicellatis ; perianthio 6-partito, seg- 

 ments linearibus 2.5-3 mm. longis acutiusculis saepissime basi 

 bidentatis ; staminibus perianthio longioribus ; capsulis maturis ob- 

 longo-lanceolatis ca. 1 cm. longis glabris rerlexis. — 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 rerlexed fruit. 

 y Schoenocaulon caricifolium Greenman, n. comb. Veratrum cari- 

 cifolivm Schlecht. Ind. Sem. Hort. Hal. 8 (1838). Asagraea carici- 

 folia Kunth, Enum. PI. 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- 

 |v* tical with Dr. Gray's species. S. caricifolium differs from S. officinale 

 ^ in having narrower leaves, shorter scapes and inflorescence, and rela-
