rHANEROGAMIA. 363 



3. The species of Ventilago, a genus of Bhamnaceae. Mr. 

 Benthain reduces the Indian species, of which sufficient material 

 has been received, to three, of which diagnoses are given. 



4. The Memecyla of Cuming's collections, with the synonymy 

 of four species. 



5. A Chinese species of Calogyne, a genus of Groodeniaceae. 

 Curious as the second species of the order, apart from the mari- 

 time Sccevolas, found out of Australia. It was collected near 

 Amoy.

"With detailed descriptions of 262 species. A plate of each is 

 furnished ; in the case of C. baccans, C. Bengalensis, C. indica, 

 and the more variable types, a series of figures is given. Seven 

 species are described for the first time. 



Borszczow, El. — Die Aralo-Caspischen Calligoneen. Petersb. Mem. 

 Tom. in. No. 1. 45 pp. with 3 plates. 



Contains observations on the history and literature of the 

 genus Calliffomcm, Linn, (with which the genera Fterococcus, 

 Pall, and Calliphysa, P. et M. are united), its modus crescendi, 

 physiognomy, development, geographical distribution and sta- 

 tistics, properties and uses. 



The total number of species is reckoned at 25, all of which 

 are exclusively Asiatic, with the exception of G. comosum, which 

 extends from Persia, across North Africa to the Canaries. The 

 majority of species — at least 14— are peculiar to the Aralo- Caspian 

 basin. Many of the species of Calligonum afford a gummy 

 product, as observed by Pallas, which flows from wounds both 

 in the branches and older stems ; in very hot weather exuding 

 from herbaceous parts of the plant. The commonest species, 

 C. Pallasia, besides serving as a good fuel, furnishes the food 

 of the Steppe-mice (Cricetus, Meriones) which live under its 

 bushes. Most of the species are capable of affording a dye, 

 which has not, however, been investigated. Twenty Calligonums 

 are described ; eleven of them, discovered by Herr Borszczow on 

 his journey in 1857-8, as new.
