Iris caroliniana is an_ interesting ue from Virginia and 
Ws Ac pct in North 
— hs was ee by the late Mr. S. Watson from a 
in cultivation at Kew for some ten years previous]; y. 
_ The Corokia figured at t. 8466. has been in cultivation at Kew 
the species illustrated, 
Opuntias in the Canary Islands.— Whilst soiling: some months i 
the Canary Islands I took the opportunity to study the various 
Ha of Opuntia growing there, and noticed the following species 
n Grand Canary and Teneriffe :— 
1. Opuntia brasiliensis, Haw. In a garden at Orotava, Teneriffe. 
Lowe records this in his “ Flora of Maderia,” as having 
been introduced into that island, but he does not state if it 
had become wild or not, in his time. 
2. Caustic ficusindice, Webb and other writers, but not the 
e O. Ficus-indica = O. Tuna of some writers. This 
se Webb called Opuntia Ficus-indica, in his “ Histoire 
at. des Iles Canaries,” iii., 1840, p. 308, stating that it 
has two varieties :— 
a. spinosa, with yellowish-white spines. 
p. inermis aut parce spinosa, unarmed or nearly so. 
It is also the plant which was i et paar gms by 
Bourgeau under his No. 1239, the e of Cactus 
tcus-indica, and is called O. Cea saien by "Pitard and 
Proust—“ Les Iles Canaries,” 1909, p. 197. It is certainly 
not the O. Ficus-indica of the coast regions o 
Mediterranean, nor the true Cactus Ficus-indica, L. 
It appears to have been the plant used principally for the 
rescneiags industry, and is still extensively cultivated at 
Arucas, in Grand Canary, for this purpose. Where grown 
for eur and feeding the Cochineal insect it rarely seems 
to flower and fruit, but elsewhere—on abandoned cochineal 
plantations—its rich orange flowers, turning to pink as they 
fade, are abundantly produced and the fruit is eaten in 
considerable quantity. 
~ The thorns of this Opuntia are short and white, generally 
two or three together, but in old plants often single, 
almost entirely absent.
