THE CACTACEAE. 



On page 76, vol. 11, under Pachycereus hpidanthus, insert: Since the appearance of 

 volume II, we have received flowers of this species from Wilhelm Weingart, which show 

 a very close likeness to those of Escontria chioiilla. The fruit of the latter, however, is a 

 juicy edible berry, while that of the former is described as dry. The illustrations here printed 

 may lead to the rediscovery of this rare plant. 



Figure 244 is from a photograph of a plant grown in Washington, showing a joint as 

 it came from the field and also the young growth as developed in the greenhouse ; figure 245 

 is from a photograph of two flowers and a spine-cluster. 



Fig. 244. — Pachycereus lepidanthus. 



On page 78, vol. 11, under Leptocereus leonii, insert :" Specimens collected in June 1923, 

 by Brother Leon and Dr. Roig on Loma de Somorrostro, Jamaica, Havana Province, Cuba, 

 show that the fruit of this species becomes 6.5 cm. long by 5.5 cm. thick, when fully mature. 

 The fruits are borne near the ends of the branches, 3 or 4 close together. 



On page 76, vol. 11, under Cereus tetazo, insert: Pilocereus tetetzo cristatus Weber 

 (Schumann, Gesamtb. Kakteen 176. 1897) is only a name and so is Cephalocereus tetetzo 

 (Monatsschr. Kakteenk. 19: 73. 1909) and Cereus tetezo and C. tetetzo (Monatsschr. Kak- 

 teenk. 17: 79. 1907).
