seed were gathered, which latter have already germinated. The 

 fruit is a pendulous, dry, leathery, not opening capsule or berry, 

 of deep brown color, with (as the ovules, described p. 40, indi- 

 cated) thin seeds ; the species therefore belongs to Clisioyucca, 

 the character of which section will have to be slightly modified. 

 Those botanists who described the fruit as pulpy must have con- 

 founded it with that of Y aloifo/ia, as indeed seedsmen in Europe 

 also have done, whose wrongly-named seeds, raised in Italy or 

 Sicily, I have on page 40 erroneously described as those of Y 

 gloriosa. 



The best formed fruits, seen by me, were, before full maturity, 

 3 inches long, 1 inch in diameter, prismatic, cuspidate, the 3 

 wider sides forming the back of the carpels and opposite the outer 

 segments of the flower, and 3 alternate sides, corresponding to 

 the commissures, only half as wide as the others, depressed and 

 separated from the others by 6 prominent ridges. The fruit at 

 this stage is altogether like a small fruit of the Y. aloifolia, only 

 more pointed. At maturity its parenchyma dries up, the texture 

 becomes leathery and the markings less distinct. Fruits infested 

 by larvae are often smaller, constricted about the middle or vari- 

 ously twisted. In such fruits the rains of a wet autumn are apt 

 to penetrate through openings made by the larvae, and cause the 

 germination of the seeds in the closed pod — Seeds 7-S mm. in 

 the longest diameter, i-ii mm. thick, with an entire albumen; 

 differing from the seeds of the capsular Yuccas only by the entire 

 absence of a wing-margin. 



Page 41. Y. Treculiana and Y. cavaliculata are synonymous; if, 



as it is said, no sufficient character accompanies the name given 

 by Carriere in 1S5S, and if the first description of Y. 'Ircculiana 

 was published by Herincq, 1863, in the Horticulteur Francais, then 

 Hooker's name of Y. caualiculata, published with description and 

 figure in i860, would have precedence. — Fruits lately obtained 

 from Southwestern Texas are 3-42 inches long and 1-1 \ in diam- 

 eter, pointed but scarcely rostrate, somewhat less distinctly six- 

 angled than those of Y. aloifolia. Seeds 7-S mm. wide, 2-3 mm. 

 thick, the smallest ones the thickest. — Ytcca aspera, Regel, Gar- 

 tenfl., is the same, to judge from a specimen cultivated here ;
