 the gills. The fungus had evidently been broken off before it 

 was attacked by the parasite, as the fractured surface is equally 

 iDfested Avith the rest of the plant. The mycelium does not 



penetrate deeply into the substance of the matrix. The sporidia

^^OMMExcED the examination of this order in 1859, by arranging 

 and determining the species contained in Griffith's, Heifer's, and 

 -falconer's Herbaria, recently distributed from the Eoyal Gar- 

 tiens, Kew. About the same time, I described the Ceylon species 

 lor Mr. Tinvaites's enumeration of Ceylon plants. Before I left 

 Kew to return to India, in 1861, I had examined all the Indian 

 species in the Kew herbarium, and named and described many 

 01 the new ones. On my arrival in Calcutta, I fonnd the her- 

 barium of the Calcutta Botanical Gardens exceedingly rich in 

 specimens of this order; while several new species, which I had 

 ^^ot seen in London, were discovered in the collections of plants 

 by ^Masters, Simons, Jenkins, and others, deposited in this her- 

 oarmm. "With the exception of the Ilookerian-Thomsonian her- 

 barium, none of the specimens were determined ; and thus the 



^^amination of all the Indian species had to be undertaken 



again. 



^ty original intention was to include in this enumeration all 

 e Asiatic species of Aeanthacece, in the same manner as I 

 ^numerated the African species in the paper I published in the 

 seventh volume of the Society's Proceedings. The want of speei- 

 ^^us from Java and the Malayan archipelago forced me to aban- 

 *^ou tills plan, and I have therefore restricted myself, for the 

 Present, to the elucidation of the AcantJiacece of India. Through 

 the kindness of Professor Miquel, who has sent me the Aca'n- 

 ^«C(?^ of tlie Leyden lierbarium for examination, and of my
