/944. Opuntia FRAGILIS, Nutt., var. rrutescens. (O. fru- 
tescens, Engel. MSS.) Near the Musket-thickets, (vide No. 
233,) on the Colorado ; often acquiring the height of four or 
five feet, with a branching ligneous stem, covered with light 
gray bark, and sometimes with lichens. It bears bunches of 
small capillary spines, with one larger one (4-5 lines long ;) 
these disappear from the older stems. "The wood is hard and 
close-grained. The younger branches are green and terete, 
(or angular when withered,) and bear the ultimate articula- 
tions, which are about an inch long, and very easily break off. 
hese bear when young, like other Opuntie, short terete 
Subulate leaves, with a single spine in their axils, and above 
this a bunch of small ones. The specimens are not in flower, 
but are covered with the obovate umbilicate searlet fruits, 
Which are about eight lines long, fleshy, but not juicy, and 
contain very few (2-5). white, ‘compressed seeds. What is 
most remarkable, these fruits are often proliferous, and bear 
from one to four or five new branches from the upper 
bunches of spines. The fruit either falls off with these 
branches, or else dries up, persists and finally forms part of 
the Stem.! - + ú Pr te "
