THE PLANTS AND GARDENS OF THE CANARY ISLANDS. 
67 
tives belong to the genus Sempervivum alone. There are 
fifty species, many of them most striking and showy. Fourteen 
of these are grown at Kew. Of the closely allied but peculiar 
genus Monanthes there are two species at Kew, M. agriostaphys 
and M. polyphylla. This genus was supposed to be confined to 
the Canary Islands, but Sir Joseph Hooker and Mr. John Ball 
found M. murale growing a few years ago on the Greater Atlas. 
A peculiar species of Rosacese (Bcncomia caudata) closely 
resembles in habit Potcrium Sanguisorha. Of the Legu- 
minosae there are several plants familiar to us in English green- 
houses. Amongst these are Cytisus canarieiisis, with yellow 
flowers, C. ptrolifer, with whitish flowers, and the beauti- 
ful Lotus Berthelotii (L. peliorhynchus), with red and yellow 
flowers and glaucous green linear leaves. Amongst shrubby 
Convolvulacese the Canary Rosewood or " Guadil " [Convolvulus 
floridus) is a lovely plant, with glaucous leaves and masses of 
pure white flowers. The almost leafless Ceropegia dicJiotoma is 
a singular Asclepiad that is apparently somewhat rare in the 
islands. It has long been an inhabitant of the succulent 
house at Kew. 
Jasminum odoratissimum, introduced to English gardens in 
1656, is shrubby in habit and fairly hardy. The Canary 
Arbutus- tree [Arbutus canariensis) is found of large size in woods, 
the flowers are greenish white, and the berries are made into 
sweetmeats. Perhaps one of the most striking Canary plants is 
Ga7iarina campanulata, a climber with a tuberous root and dark 
red flowers. There is another Campanula which I have not so far h 
seen (Laurentia canariensis). There are a dozen species of 
the boragineous genus Echium found in the islands. E. simplex, 
" the Pride of Teneriffe," has a single dense spike of flowers about 
8 feet high ; others are shrubby and some herbaceous. All have 
bright-coloured flowers, purple, with shades of red, white, or 
rosy. 
The Canary Foxglove is Isophxis canariensis. This grows 
in woods under the shade of the Laurel and Arbutus trees. 
It is now in flower at Kew. The closely allied I. isabelliana 
I saw once only in Barranco del Rio in Teneriffe. It does 
not appear to be in cultivation in this country. A peculiar 
genus of Labiateaj with white woolly leaves [Sideritis) is 
represented at Kew by a single species, S. canariensis. This
