the garden at Pencarrow, Bodmin, bearing male flowers and female 

 cones on the same tree, which is apparently most unusual. — G. B. 



AristOtelia racemosa. By Sir J. D. Hooker (Bot. Mag. 7868).— 

 Nat. ord. Tiliacece, tribe Elcsocarpece. Native of New Zealand. It is a 

 common shrub, being the first to appear after the forests have been cleared. 

 The flowers are in panicles, 3-5 ins. long, J in. diam. The petals are 

 3-5-lobed and rose-red. — G. H. 



Azalea pontica. By P. Hariot (he Jard. March 20, 1902, p. 81).— 

 Statistics of the flowering of this shrub at Moulins, in Central France, 

 show that the date of commencement ranges from April 5 to May 7. 

 Besides the honey bee, which extracts the poisonous honey of their 

 flowers, they are especially visited by drones, and the large Cabbage 

 white butterfly.— C. TP. D. 



Banana-leaf Blight. By F. S. Earle (Jourri. N. Y. Bot. Gard. 

 vol. iv. Jan. 1903). — A serious Banana disease has been observed in one 

 locality, in the island of Jamaica. It causes the browning of the vascular 

 bundles in the veins and midrib of the leaves. This is soon followed by 

 the blackening of the entire leaf-blade, and eventually by the decay of 

 the leaf and petiole. The terminal bud is not attacked, but continues to 

 push out fresh leaves. These soon become infected in turn, so that 

 usually not more than three or four of the younger leaves are free from 

 the disease. Infected plants are much stunted in growth, and do not bear 

 fruit. If so destructive a disease should by any chance become widely 

 scattered, the results would be truly disastrous. Apparently it is due to 

 a bacterial parasite. Cultures were obtained, and it is hoped to study the 

 disease further. — M. C. C. 



Barberries, The. By W. J. Bean (Garden, No. 1628, p. 71 ; 

 31/1/1903). — Probably between sixty and seventy species of Barberry are 

 now known to botanists. Some of the species are so much alike that in 

 gardens the genus may be quite adequately represented by growing about 

 half of them. This and succeeding articles give the most useful species 

 from a garden point of view, with notes about their culture. — E. T. C. 



Barleria lancifolia and B. damarensis. By Spencer Moore 

 (Jotcm. Bot. 480, pp. 407-8 ; 12/1902)— Redescription of two of 

 T. Anderson's types from tropical Africa, now in the herbarium of Trinity 

 College, Dublin. — G. S. B. 



Barleria taitensis. By Spencer Moore (Jmrn. Bot. 478, p. 343 ; 

 10/1902). — Description of a new species, collected by Mr. Kassner at the 

 Makindo River, British East Africa, from specimens in the Natural 

 History Museum. — G. S. B. 



Bauhinia acuminata. By Sir J. D. Hooker (Bot Mag. tab. 7866). 

 Nat. ord. Leguminosece, tribe Bauhmiece. Native of tropical Asia. It 

 is a shrub or small tree, 8-10 ft. high. Leaves bifid nearly to the middle, 

 glabrous above, but downy beneath. Flowers solitary or few in a short 

 raceme, 2J ins. broad, pure white. Though long grown at Kew, it 

 flowered for the first time in 1 -G. H.
