IV. — On some new or imperfectly known Indian plants, — 

 by S. Kurz, Esq., (Abstract.) 



This paper contains descriptions of 26 new species belonging 

 to various families, chiefly of phanerogamic plants. Besides that 

 varied and very important information is given regarding other 

 Indian plants which were up to this imperfectly known, or incorrectly 

 identified. 



The paper is accompanied by two plates ; on one of them three 

 figures are given representing the distinctive characteristics in the 

 sheaths of Schizostachyum brachycladum, Zollingeri and longispicttlafic/n, 

 considered by Col. Munro as belonging to one andtho same species, 

 but evidently distinct. On the other plate an illustration of the 

 interesting Javanese fern Ileniionitis Zollingeri, Kurz, is supplied, 



* This is the most common Alga in Lower Bengal, covering in large spongy 

 patches the ponds, ricefickls, &c., and adding much towards a natural manure 

 of the fields. (S. Kuju.
