 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

 mm. Plate l,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? parvi flora, 

 the description of the filifcrous 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.
