On page 37, vol. 1, under Nopalea auberi, insert: 
Opuntia aubert was described as from Cuba, but as no Nopalea is known from Cuba 
we have been unable to account for this reference. The following incidents may explain it: 
L,. Pfeiffer described the plant in 1840 just after his return from Cuba, where he had 
gone with Otto in 1838. At Havana they visited the Botanical Garden, then in charge of 
Pedro Auber, for whom this plant was doubtless named. It is also stated that, although 
Pfeiffer made this trip especially to gather cacti, he saw only one species, Opuntia horrida. 
The probabilities, therefore, are that this plant was obtained from the Botanical Garden 
at Havana, perhaps with a statement from Auber that it was Cuban. 
On page 37, vol. 1, under Nopalea dejecta, add the synonym: Nopalea angustifrons *

On page 42, vol. 1, under Mazhuenia brachydelphys, insert the synonym: Opuntia 
brachydelphis Schumann in Just, Bot. Jahresb. 26': 343. 1898. 
Insert: Mammillaria brachydelphis is a clerical error for Opuntia brachydelphis. 
On page 42, vol. 1, under Opuntia, add the synonym: Cactus Lemaire,f Cactées 86. 
1868. Not Linnaeus, 1753. 
On page 46, vol. 1, under Opuntia ramosissima, insert: Opuntia tessellata denudata, 
according to C. R. Orcutt, is only a form—spiny joints frequently occurring on the same 
plant with the spineless form; it is common in the Mojave Desert, California. It was 
mentioned by Alverson (Cact. Cat. 6) while O. ramosissima denudata is listed by Weinberg 
(Cacti 22). O. ramosissima cristata is mentioned by Schelle (Handb. Kakteenk. 41. 1907).

On page 47, vol. 1, under Opuntia leptocaulis, add the synonym: Opuntia californica 
Engelmann in Emory, Mil. Reconn. 158. 1848. 
Also insert: Opuntia stipata (Schumann, Index Gesamtb. Kakteen 830. 1898) refers to 
O. leptocaulis stipata.

On page 49, vol. 1, under Opuntia caribaea, insert: Dr. Britton endeavored to find 
this plant in Trinidad in 1920 and 1921 but failed and he could not learn anything about 
it. It appears probable that the drawing sent by Mr. Lockhart to Kew in 1825 was made 
from a Venezuelan plant.

* The Index Kewensis refers this name to Opuntia leucacantha, but the illustration shows that it belongs to / 
+ Lemaire in his Les Cactées, published in 1868, takes up the name Cactus for certain of the low, depressed, much 
branched or cespitose species of Opuntia. He lists a number of these on pages 87 and 88, but as they are not connected 
through published species their identification is made only by inference.
