Notes on Afghanistan Algae. By Dr. Julius Schaaksciimidt, 

 Lecturer on Cryptogamic Botany and Vegetable Anatomy, 

 Assistant in the Botanic Garden of the Eoyal Hungarian 

 University at Kolosvar [Klausenburg]. (Communicated by 

 Prof. Oliver, E.L.S.) 



[Eead March 6th, 1884.] 

 (Plate V.) 

 The following list of Afghanistan Alga? is the result of the 

 investigation of some dried Phanerogamic Plants collected in 

 Afghanistan by J. E. T. Aitchison, F.L.S., Surgeon-Major in 

 H.M. Bengal Army, in the Afghanistan Expedition of 1880. 



I am indebted to Professor Dr. A. Kanitz, whose kindness has 

 enabled me to draw up this account, for permitting me to exa- 

 mine many plants from the interesting duplicates distributed by 

 the Kew Herbarium. 



I found the enumerated Alga? chiefly adhering to the specimens 

 of Ammannia pentandra, Eoxb. ["417. Shalizan, in rice-fields, pro- 

 fuse"*], forming fine bluish-green incrustations around the stems 

 and on the leaves. Many interesting forms were found (perhaps 

 Bacillariacea?) in the BUiall earthy particles remaining attached 

 to the roots. One species, viz. Hantzschia Amphioxys, was only 

 found on the roots of Anemone tetrasepala, Eoyle [" 18(5, 237, 

 332 = 463 (1879). Safed-koh range, on the margins of forests, 

 and in open grassy slopes on the inner hills, at an altitude of 

 from 7000 to J 0,000 feet "fl-
