WEATHERBY. — MEXICAN PHANEROGAMS. 423 
cescens duplo brevioribus. —Gurrrero: between Ayusinapa and 
Petatlan altitude 1500-2000 m., Dec. 14, 1894, Nelson, no. 2120 (in 
hb. U. 8. Nat. Mus.). Near A. leptophyllum Baker, from which it 
differs in its even more slender habit, narrower and longer leaves, 
and several-bracted stem. Very similar also to Echeandia Pringlei 
Greenman, but with free anthers. 
Anthericum uncinatum, n. sp., scaposum, radicibus medio in- 
crassatis, collo radicis dense fibroso, foliis (6-7) 8-12 em. longis 
6-10 mm. latis pallide viridibus saepius patentibus valdeque fal- 
catis in siccis conduplicatis membranaceis marginibus manifestis albis 
cartilagineis ciliolatis lente nervatis, caulibus circa 3 dm. altis simplici- 
bus scabris vel hirtellis 1-2-bracteatis bracteis setaceo-acuminatis 
chartaceis, pedicellis floriferis 5-7 mm. longis infra medium articu- 
latis, perianthii flavi (?) segmentis 8-12 mm. longis, filamentis papil- 
loso-crispatis circa 5 mm. longis antheris longioribus, capsulis immatu- 
ris brevibus ovoideis. —Duranco: Otinapa, July 25-Aug. 5, 1906, 
Palmer, no. 437. Near A. scabrellum Baker, from which it differs in 
its cartilaginous-margined and strongly falcate leaves, similar to those 
of A. drepanoides Greenman. From the latter species it differs in 
its scabrous stem, smaller size, and fewer, chartaceous bracts. In A. 
drepanoides the bracts are about 5, and the lower are foliaceous and 
falcate, like the root-leaves. : 
Nemastylis (§ Chlamydostylus) latifolia, n. sp., bulbo ovoideo 
tunicis brunneis friabilibus, caule simplici subflexuoso in speciminibus 
visis circa 4.5 dm. alto folium unicum erectum bracteamque vaginan- 
tem gerente, folio radicali uno lineari-lanceolato longe acuminato apice 
setaceo 3 dm. longo 1-1.5 cm. lato plicato valde nervato, folio caulino 
simili inflorescentia breviore vel eam aequante ejus vagina 3-3.5 cm. 
longa scariosi-marginata, bractea acuminata scariosi-marginata 7.5-8.5
