FIGS. 47, 48. Tacinga funalis. Xo.6. 



This species was sent from Mexico by Karwinsky, who supposed it was an Opuntia. 

 When described by Salm-Dyck in 1850 it had not flowered. It was re-collected by 

 Edmund Kerber near Colima, Mexico, and flowered for the first time in cultivation in 1879. 



Our description is drawn chiefly from a plant now in the New York Botanical Garden, 

 obtained from M. Simon, of St. Ouen, Paris, France. In the original description it is 

 stated that the young spines are 2 to 4 and rose-colored, but afterwards 18 to 20, gray and 

 deflexed. 0. nopalilla Karwinsky (Salm-Dyck, Cact. Hort. Dyck. 1849. 68. 1850) was 

 first given as a synonym of this species. 



Figure 43 represents a joint with young fruit, from a plant sent by M. Simon, St. Ouen, 

 Paris, France, in 1901. 



7. Nopalea inaperta Schott in Griffiths, Monatsschr. Kakteenk. 23: 139. 1913. 



Described as 5 to 7 meters high, but in cultivation much smaller, diffusely branched, often 

 bush-like; trunk very spiny; terminal joints rather small, obovate, 6 to 17 cm. long, strongly 

 tuberculate, bright green; spines usually 3 to 6 at areoles of young joints, more at old ones, yellowish
