bulletin have been known for years and used successfully. They are 

 named Sphaerostilbe coccophila (Tul.), Ophionectria coccicola (E. & E.), 

 Myriangium Duriaei (Mont.), Aschersonia flavo-citrina, Aschersonia 

 aleyrodes (Webber), and the brown fungus — which has not yet received 

 a scientific name. Each fungus is recorded with the insects specially 

 affected, and how it is to be applied. — M. C. C. 



Furcraea, Literature and Synopsis of. By J. R. Drummond 

 (Bep. Miss. Bot. Gard. 1907, pp. 25-75 ; 4 plates). — An epitome prepared 

 at Kew, giving the history, distribution, and synonymy of ten admitted 

 species and six others " imperfectly known but possibly valid." — G. S. B. 



Goldenseal : its Cultivation and Handling*. By Alice Henkel 

 and G. F. Klugh (i7.Sf.il. Dep. Agr., Bur. PI. Ind., Giro. 6 ; June 1908 ; 

 figs.). — A description of this drug plant (Hydrastis canadensis) is given, 

 and methods of its cultivation and the preparation of the root for market 

 are detailed. The demand for the root amounts to from 200,000 lb. to 

 300,000 lb. annually, but it is pointed out that the point of over-production 

 might easily be reached. — F. J. C. 



Grafting", Chemical Changes in Scions. By L. Darnel (Bev. 

 Hort. October 1, 1908, p. 459). — Experiments by Professor Ch. Laurent 

 have shown by analysis of ashes that grafted plants are affected in their 

 chemical constituents by the stock, and vice versa. Belladonna grafted 

 on tomato resulted in its particular alkaloid being detected in the latter, 

 which normally is entirely free. It was also demonstrated that differences 

 in chemical constitution were correlated with different resistance to fungoid 

 disease, a point of great practical importance. — G. T. D. 



Hardiness of Plants. By Jules Rudolph (Bev. Hort. August 16, 

 1908, p. 372). — Capacity to stand frost depends considerably upon the 

 source of the seed in the case of somewhat tender vegetables, seed from 

 a cold country yielding harder offspring, and vice versa. — C. T. D. 



Hevea brasiliensis. Fungi of (Die Bilze von Hevea brasiliensis— 



Para Kautschuk). By T.Petch (Zeit.f. Pflanzkr. (1908), xviii. 2, 81).— 

 The fungi known to attack this plant, which has lately become so important 

 as a producer of rubber, are dealt with under the headings of " Leaf 

 Diseases," "Root Diseases," "Stem Diseases," "Fruit Diseases." One 

 fungus, Eurotium candidum, is described as affecting the prepared 

 rubber. — F. J. C. 



Hibiscus aponeurus. By T. A. Sprague (Bot. Mag. tab. 8231).— 

 Nat. ord. Malvaceae ; tribe Hibisceae. Tropical East Africa. Plant 

 erect, shrub-like, 1-4 feet high ; leaves ovate, inch long ; flowers 



solitary, axillary ; corolla 1 inch diameter, brilliant scarlet.— G. H. 



Honey and Pollen-yielding Plants in Texas. By A. F. Conradi 

 (Jour. Econ. Entom. i. 3 ; pp. 191-203 ; June 1908). — A list of many 

 plants grown in Texas, with notes on the yield of honey and pollen from 

 each, the time of flowering, and the distribution of the plant through the 

 State of Texas.— F. J. C.
