266 THE CACTACEAE. 
Cactus italicus referred by the Index Kewensis to Tenore (Steudel, Nom. ed. 2. 2: 
246. 1840) occurs first in 1831 (Tenore, Syll. Pl. Neop. 241) where also occurs the name 
Opuntia italica. Both are unpublished but doubtless refer to some species of Opuntia. 
Cactus PARVIFOLIUS Ehrenberg in F. G. Dietrich, Vollst. Lex. Gaertn. 2: 416. 1802. 
An upright, cylindrical, almost articulate stem; the upper part bedecked with small, cylindrical, 
fleshy, pointed leaves; on lower part of the stem, at the place where the leaves are attached, stiff 
bristles are formed which are surrounded at the base by a whitish-gray, woolly substance; in old age 
the stem requires a support on account of its slender growth; 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 vulnerator Cortes (Fl. Colombia 69. 1897) and C. guasabara Cortes (FI. 
Colombia 208. 1897) are different names for the same plant. From the brief descriptions 
it is difficult to identify this plant but it certainly is not a Cereus. It suggests some 
sheathed-spined Opuntia such as O. tunicata 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. Suce. 75. 1819; Cactus regalis Sprengel, Syst. 2: 476. 1825; Cereus childst Blanc, 
Cacti 39, No. 375. 
Insert: C ereus 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.

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 country it is more likely to be Trichocereus chiloensis.
