near Florence. So far the plant has not flowered, neither have the 
three large specimens which Dr. Ragionieri sent us in October, 
1909. 
Bocconia. 
B. frutescens, a shrub with decorative leaves but insignificant 
flowers, was received in February, 1902, from Cay. C. Sprenger, 
of Naples. 
BouGAINVILLEA. 
B. spectabilis is a feature of Riviera gardens. The variety 
lateritia, also known as B. Warscewiczit, only differs in the brick- 
red colour of its bracts and in being somewhat less hairy than the 
type. B. glabra and its lower form or variety Sandervana are 
shrubs with glabrous leaves, and almost equally decorative. I 
have not seen Bougainvilleas producing fruits. 
Bougainvilleas were first bought from the Jardin d’Essai, 
Hamma, Algeria, in February, 1873. 
BRACHYCHITON. 
B. acerifolius, the ‘‘ Flame tree,’ does not blossom every year, 
but in some seasons it is literally covered with flowers. Our 
largest plant is 7-40 m. high and its stem has 87 cm. circum- 
ference at base. B. Bidwilli is a smaller tree, producing every 
summer beautiful red flowers and ripening fruits. Its var. planior 
has more opaque and flatter leaves. B. lwridus,a very handsome 
young tree, has not yet flowered. B. populneus is frequently 
planted along the Riviera. B. rupestre was received from Kew in 
- January, 1879. It is growing very slowly and has not made much 
progress in height during the fifteen years that I have observed 
it, except that the stem has become much thicker at the base and 
the plant is more branched. It is now a small tree with conical 
stem and pyramidal crown. 
BuDDLEIA. 
Buddleias are among the most beautiful plants in the garden. 
B. madagascariensis is a huge climber covered in spring with 
hundreds of long fine yellow racemes. B. awriculata is a smaller, 
white-flowered not climbing shrub. B. americana forms a large 
shrub or almost a tree with stems of considerable size. It was 
received from Villa Thuret and planted in November, 1874. JB. 
globosa was procured from Messrs. Veitch & Sons by Mr. Daniel 
Hanbury in January, 1868. B. Colvilei (not B. Colviller) came 
from Kew some years ago, but does not grow so well here, nor has 
it ever flowered. 
Buxus. 
B. balearica, procured from Hyéres in December, 1867, is a 
slow growing small tree. 
CALIBANUS. 
A monotypic new genus of Nolinee; see note under Beaucarnea. 
C. Hookerii Trelease is the exact name now for Dasylirion Hook- 
erit Lem. The plant has a depressed globose trunk with numerous
