This species occurred in the localities mentioned above in company 

 with Qicourta pl((tii2)tpni Welw. Herb. No. 1752 ; see Welw. Sert. 

 Angol. p. 26 (1869). It occurs also in the Congo district, having been 

 found by Monteiro at Quiballa flowering in the month of April. The 

 fungus n. 387 grew on the branchlets of Dulhoustea in the district 

 of Cazengo. It is very nearly related to the North Indian species
