nite locality, Ehrenherg (hb. Gray). Specimens secured by C. Conzatti 

 and V. Gonzalez at Etla, Canada de San Gabriel, State of Oaxaca, alt. 

 3000 m., 8 August, 1897, no. 323 (hb. Gray), are apparently referable 

 to this species. 



Schoenocaulon Ghiesbreghtii Greenman, n. sp., caudice erecto 

 10-12 cm. alto reliquis brunneis aut nigrescentibus fibrosis squamarum 

 et foliorum primorum obtecto ; foliis linearibus attenuatis 4-8 dm. 

 longis 2-6 mm. latis 7-13-nerviis utrinque glabris ; inflorescentia 

 1-1.2 dm. vel ultra longa 1.5-2 cm. diametro densiflora; bracteis late 

 ovatis 2.5 mm. longis obtusis 5-nerviis; floribus sessilibus vel breviter 

 pedicellatis ; perianthio profunde 6-partito, lobis anguste oblongis 

 4-4.5 mm. longis obtusis integris vel subintegris 3-5-nerviis; fila- 

 mentis perianthio duplo vel ultra longioribus uniforme recurvatis ; 

 fructu ignoto. — State of Chiapas, Mexico, without more precise lo- 

 cality, Dr. Ghieshreght, no. 672 (type, in hb. Gray) ; without definite 

 locality, alt. 2130 m., Berendt (hb. Gray). This species is rather strik- 

 ing on account of the recurved filaments. In this respect it resembles 

 >S'. tenuifoUum Robinson & Greenman, but in other and more essential 

 characters it is amply distinct.

 alto a reliquis atrobrunneis vel nigrescentibus fibrosis squamarum 

 foliorumque exteriorum obtecto ; foliis gramineis 6-10 dm. longis 

 2-7 mm. latis 9-13-nerviis utrinque glabris margine inconspicue hir- 

 tellis ; scapo erecto 8 dm. vel ultra alto nudo subancipiti aliquid 

 glauco ; inflorescentia elongata 1 usque ad fere 5 dm. longitudine

 parvis scariosis suberoso-marginatis ; floribus breviter pedicellatis ; 

 perianthio alte 6-partito, segmentis lineari-oblongis ca. 2.5 mm. longis 

 integris vel basi bidentatis apicem obtusum versus paulo ampliatis 

 incrassatisque ; staminibus perianthio longioribus ; filamentis persis- 

 tentibus ; capsulis immaturis nee non pedicellis et segmentis perianthii

 Jalisco, Mexico, 11 November, 1889, C. G. Pringle, no. 2938 (type, in
