﻿ADDITIONS TO THE GENUS YUCCA. 229 



istically subsimple and slender in habit and differing also 

 in its tomcntose inflorescence and very circinately browu- 

 filiferous juvenile leaves. 



This was described and named by Mr. Baker from young 

 but fairly large specimens cultivated in 1870 by Mr. Wilson 

 Saunders, and a leaf of F. /l/i/era" collected in 1809 by 

 Engelmann from a plant which Ccls, of Paris, had received 

 from Mexico through Galeotti, evidently represents the same 

 species, and Engelmann noted seeing it also at Gucdcney's 

 under the more erroneous name canaliculata. On the other 

 hand, the straighter, slenderer and paler marginal threads 

 shown by type leaves of Y . scabrifolia and Y. polyphylla 

 (a name later abandoned by Mr. Baker without explanation) 

 scarcely permit those names to be removed from their former 

 location under australis in the absence of other information 

 than has yet been published. 



Yucca £iidlichiaua n. sp. 



Acaulescent. Leaves few, erect, thick and rigid, 1.5 X scarcely 50 

 cm., half-round near the base, narrowly V-shaped above, smooth, bluish- 

 green somewhat dappled beneath with longitudinal dark dashes near the 

 very short thick gray point, the basal part of which is blackish-purple: 

 margin brown, rather finely or sparingly filiferous below, the stiff recurving 

 fibers becoming short and very thick near the apex. Panicle shorter than 

 the leaves, freely branched, the branchlets about 6-flowered. Flowers on 

 filiform pedicels over 2.5 cm. long, creamy to dull purplish brown, very 

 small for the genus: perianth segments ovate, acute, about .8X 1-5 cm.: 

 filaments short, minutely papillate: ovary oblong, surmounted by a slen- 

 der style of about half its length. Fruit pendent, subglobose or broadly 

 ellipsoidal, 2X2.5 to 3 cm., with thin flesh quickly drying: seeds 5 to 6 

 X 6 to 7 mm., rather thin, the albumen shallowly runimated. — Plates 

 15-17. 



Marte, on the Mexican Central Railway, Coahuila, Mexico, 

 and elsewhere, about the Sierra de Parras, the Sierra tlel 

 Rosario, and the Sierra de la Paila. Received from, and 

 named for, Dr. R. Endlich, who states that it is called "pi- 

 tilla," and is said to produce a better fiber than that of the 

 common lechuguilla {Agave Lecheguilla). 



A very distinct and remarkable species differing from all 

 other Sarcoyuccas in its very small, often dark flowers, thin-
