have endorsed the description or reported its occurrence in 

 other locality. In De Toni's Syll. Alg., lc, it is found among 

 " species inquiridae." I have, however, already noted in the 

 work cited above that a form of Iridsea which should be. refer- 

 red to the present species is found among the dried article of 

 Iridsea in the markets. An examination of the type specimen 

 in the herbarium of Madam A. Weber van Bosse erased my 

 old question concerning the species and assured me its occur- 

 rence within our boundarj^. The plant has various character- 

 ristic points and is easih' distinguiched from other known 

 species of Irid&a. It is to be counted as a valid species. 



The plant is beautiful crimson purple in colour when fresh 

 and remains slightly changed after drying. Younger frond is, 

 when dried without mounting on paper, more or less trans- 

 lucent and like a parchment paper, with labyrinthic surface as 

 figured by Kutzintg due to unequal contraction. In older ones 

 the substance is thick and cartilaginous and the surface is 

 smooth. The base of frond is narrow cuneate, generally abrupt- 

 ly expanding upwards into long ovate blade, which may be 

 simple or bilobed, with undulated margin. The cuneate basal 

 portion is often dichotomously ramified with the diverging 

 points narrowed, as in other allied species. In large specimens 

 it is not seldom to find the margin of frond irregularly lobed. 



Unfortunately the specimens in my hand are all cystocarpic. 

 Had a soriferous specimen been found and proved it a Rhodo- 

 glossum, the species must be placed close by R. foliiferum J. Ag. 

 Both are much alike in appearance and separable only by the 

 shape of base of frond.
