TEie Dalbergias of S. E„ Asia. 
(The species of D. of S. E. Asia, by D. Prain ; Ann. R. B. G., 
Calcutta, X., Pt. 1, 1904.) 
This is a splendidly illustrated and admirable monograph of this 
difficult genus of Leguminosæ. So far as the Ceylon Flora is con¬ 
cerned, our species are unaltered in scope or number, but the names 
of two are changed from those given in Trimen’s Flora to earlier 
names, viz., D. Championii, Thw., to D. rostrata, Grah. (in Wall. Cat, 
No. 5,867, 1832), and D. monosperma, Dalz., to D. torta, Grah. (do. 
No, 5,873). .All are figured (Plates 36, 76, 42) in Major Prain’s 
monograph. 
D. pseudo-Sissoo Miq. of Java, as suggested by Trimen, proves to 
be identical with D. rostrata. The distribution of this species should 
be given as found also in Borneo, Celebes, Java, Malay Peninsula, S. 
India. D. zeylanica, Roxb., proves as Trimen suggested to be the same 
as our D. lanceolaria, L. f. Major Prain gives this species, on the 
authority of a Thwaites’s specimen, as “ Central Province,” whereas 
Trimen gives “ dry low country.” Thwaites’s specimens are marked 
C. P. (Ceylon Plants), which, perhaps, explains the slip ; his localities 
include Deltota in the Central Province.

(G. Bargagli-Petrucci : Le specie di Pisonia della Regione del 
Monsoni ; Lavori eseg. nel R. Orto Bot. di Firenze, 
Fase. 1, p. 73,1901.) 
A revision of the eastern species. No change is made in the 
arrangement or name of the Ceylon forms (Trimen, Flora, III., p. 
391).

Localization of Thein in file Tea PBant. 
(A. Nestler : Untersuchungen über das Thein der Theepflanze : 
Jahresb. D. Vereinig, d. Y. d. angewandten Bot. I., 
1903, p. 54.) 
Using the method described in vol. 1, p. 252, of the Annals, Nestler 
now shows that the tea plant contains thein in the seed, cotyledons, 
stem-bark, flower, and leaf. In the leaf it is found in the mesophyll, 
and possibly in the epidermis.
