oue from China {vide Prinsep in the same place, p. 85). Again Ander- 
son brought at least one other Opuntia into his garden. 
The garden existed for twenty years, and perhaps more ; Rdttler who 
visited it in 1807 was able to dry specimens taken thence of four Opuii- 
tias which are now preserved in the H erbarium of the Royal Botanic 
Gardens, Kew. I find these to be : — Opuntia monacantha, Opuntia, 
elatior, Opuntia cocJiineiifeva^ and a black-thorned plant which, so far 
as the specimen preserved at Kew goes, does not differ otherwise from 
Opuntia Billeuii and is probably it. This last Rdttler called C act in 
Tuna. 
Possibly Anderson grew even more than these four ; — at least such 
action would be in accord with his enthusiasm ; but there is no evidence 
that he did so. Without doubt the plant received from Kew was 
Opuntia cochinelifera s those from Mexico via Manila and China cannot 
be identified. 
While AndersoiPs garden was in existence William Roxburgh w'as 
busily bringing together into the newly founded ^ Calcutta Botanic 
Gardens a collection of living Cacti. One species, as said, Roxburgh 
had found established near Calcutta ; and he gave to it the name Cactus 
indicuSy and wrote of it in his Flora Indicuy published in 183'Z but written 
before 1815 (ii, pp. 475), found here and there on road sides, in forests 
and among bushes in the neighbourhood of Calcutta ; and I am in- 
formed that it is equally common not only over the whole province, but 
also on most of the adjoining districts ; he brought it into cultivation 
in the Botanic Garden at Shibpur ; he brought also into his collection 
an Opuntia from China which he named Cactus chinensisy and others as 
follows : — three received from William Hamilton, a correspondent who 
sent him many things, chiefly American, which three he enumerated 
as Cactus Opuntia, Cactus Ficus-indica and Cactus Tuna major, and 
two received from Dr. J. Anderson, viz., Cactus coccinelUfer and 
Cactus Tuna elatior. He had received the Cactus Opuntia in 1798, and 
he received the Cactus Tuna elatior in 1801 ', the dates of the receipts 
of the others are not recorded by Roxburgh, hut we may assign the 
receipt of the Caclns coccinelUfer from Anderson to the year 1788 or 
1 7 89. My identifications of the species grown by Roxburgh and Anderson 
and comments on the identifications will now be given seriatim. 
Opuutia coclliuelifera Undoubtedly i Roxburgh and Anderson 
both cultivated the true Opuntia cochinelifera. Roxburgh received his
