Walsh,' 'Mrs. A. M. Kirker, ' and 'Urania' — are recommended as 

 worth a trial. The H.T.s are considered in nine numbers (Sept. 25, 

 p. 469, to Dec. 4, p. 589), no fewer than seventy-seven varieties being 

 described and criticized. On Dec. 11, p. 602^ the Teas are dealt with. 

 This class is gradually improving in constitution, but a severe winter 

 will generally play more or less havoc with them. Good Teas are 

 still scarce, and the writer only includes fifteen varieties, of which 

 * Molly Sharman Crawford ' and ' W. E. Smith ' are specially com- 

 mended. On Dec. 25, p. 629, the Wichuraianas are dealt with, six 

 varieties being selected. — H. R. D. 



Rudbeckia, a New Annual Variety. {Jour. Soc. Nat. Hort. Fr. 

 Sept. 1909, p. 517). — Messrs. Vilmorin-Andrieux have produced a 

 practically annual variety of Rudbeclcia hirta, which bears immense 

 single yellow flowers possessing the useful peculiarity of remaining 

 fresh for several weeks, even under a hot sun. — M. L. H. 



Sapium, Mexican and Central American Species of. By H. 



Pittier {Contr. fr. U.S.A. Herh. xii. (1909); pt. 4; plates).— Nine 

 species, six of them new, of this genus of rubber-producing plants are 

 described and figured. The value of the present species as rubber- 

 producing plants has not yet been sufficiently tested. — F. J. C. 



Saprophytes, Javanese. Thismia javanica. By A. Ernst, G. 



Bernard and J. J. Smith (Ann. Jard. Bot. Buit. viii. series ii. 

 pp. 20-62 ; 9 plates). — Thismia javanica is a small saprophyte, found 

 near Buitenzorg growing in a mass of humus at the foot of a tree, 

 Lansium domesticum. Only the flower-buds appear above the surface 

 of the soil. The plant has numerous white roots, emitting adventitious 

 buds. The peduncle bears one or two flowers, having three triangular 

 sepals of a pale orange colour and three denticulate petals terminating 

 in long threadlike subulate appendices, also orange-coloured. The leaves 

 are very rudimentary. — S. E. W. 



Sarracenia and Cephalotus (Beih. Bot. Centralbl. xxv. 

 2. Abt. Heft 3, pp. 490-539; December 1909; with 58 text figs.).— 

 Dr. Josef Schweiger (Miinchen) compares the microscopic structure 

 of the roots, leaves, pitchers, pollen, and ovule in these genera. The 

 details of stomata, hairs, and glands, &c., are very thoroughly com- 

 pared, and for the most part figured. The development of the ovule 

 in each is also contrasted. He finds that the differences are far more 

 numerous than the resemblances, and especially that the development 

 of ovules and seeds are very dissimilar. He concludes that there is 

 no systematic relationship between the two forms, in spite of the 

 apparent similarity of their pitchers. — O. F. S.-E.
