m. long, something over 25 mm. wide, striate-ridged on the back. In- 
florescence 1 to 1.25 m. high, the few branches divaricate, glabrous and 
subglaucous. Flowers fascicled above the bracts, on soft articulated 
rosy pedicels, ephemeral, rosy, tubular, mostly about 35 mm. long; style 
long-exserted. Capsule something over 25 mm. long; seeds 5X8 
mm.— Plate 1, f. 1. 
Southwestern Texas; between the Rio Grande and the 
southern part of Valverde County, Kinney County, and 
the western part of Zavalla County. — Plate 84, f. 1. 
One of the puzzling plants brought in by the naturalists 
of the United States and Mexican Boundary Survey, col- 
lected between the mouth of the Pecos and the Nueces, was 
described by Dr. Torrey * under the name Yucca? parviflora, 
the description of the filiferous Yucca-like leaves and of 
the inflorescence being good, but that of the flowers and 
fruit indifferent, —the perianth noted as ‘‘ white? ’’, and 
the unripe fruit as ‘* doubtless fleshy.’’ 
In his enumeration of the known forms of Yucca in 1870, 
Mr. Baker, referring to dried specimens in the Kew herba- 
rium, as well as to the original description, characterizes the 
plant in much the same way, but observes that the flower is 
more like that of an Ornithogalum of the Pyrenaicum 
group than that of its neighbors of the genus Yucca. 
Mention is also made of the peculiarity of the flowers in an 
article on Yucca by Mr. Hemsley, who, evidently through 
a typographical error, calls the species Y. paviflora.
