266 THE CACTACEAE. 



Cactus italictis referred by the Index Kewensis to Tenore (Steudel, Nom. ed. 2. 2: 

 246. 1840) occurs first in 1831 (Tenore, Syll. PI. Neop. 241) where also occurs the name 

 Opuntia italica. Both are unpublished but doubtless refer to some species of Opuntia. 



Cactus par\tfolius Ehrenberg in F. G. Dietrich, Vollst. Lex. Gaertn. 2: 416. 1802. 



An upright, cylindrical, almost articulate stem; the upper part bedecked with small, c^-lindrical, 

 fleshy, pointed leaves; on lower part of the stem, at the place where the leaves are attached, stiff 

 bristles are formed which are siurounded at the base by a whitish-gra}^, woolty substance ; in old age 

 the stem requires a support on account of its slender gro-svth ; if the stem is cut through in the middle 

 and the wound well dried, young sprouts make their appearance at this place which serve to 

 propagate the plant. South America is its home. 



The above paragraph is a free translation of the description. 



We have not been able to identify this plant, but it is probably some species of 

 Opuntia or possibly Tacinga funalis. 



Cereus inilnerator Cortes (Fl. Colombia 69. 1897) and C. guasahara Cortes (Fl. 

 Colombia 208. 1897) are different names for the same plant. From the brief descriptions 

 it is diflBcult to identif}^ this plant but it certainly is not a Cereus. It suggests some 

 sheathed-spined Opuntia such as 0. tiinicata which has been introduced into South America 

 and is common in northern Ecuador. It is known as curuntilla or guasabara in Colombia. 



Corrections and Additions to Volume II. 



On page 4, vol. 11, under Cereus hexagonus, add the synonyms: Cereus regalis Haworth, 

 Suppl. PL Succ. 75. 1819; Cactus regalis Sprengel, Syst. 2: 476. 1825; Cereus childsi Blanc, 

 Cacti 39, No. 375. 



Insert: Cereus cyaneus Hortus is listed by Berger (Hort. Mortola 69. 1912) as a 

 South American plant grown at La Mortola. From drawings sent by Berger it is probably 

 to be referred to C. hexagonus.

 childsi. 



On page 8, vol. 11, under Cereus jamacaru insert : Cereus caracore (Gosselin, Bull. Soc. 

 Acclim. France 51: 58. 1905) belongs to the group containing C. jamacaru, that is, it is a 

 true Cereus, according to Gosselin. He does not claim that it is a good species. No 

 species of Cereus, however, are natives of Chile, from which this plant is said to have come. 

 If indigenous to that coimtry it is more likely to be Trichocereus chiloensis.
