Habitat in Camerunia in ramulis arborum, nbi ad Bomanam pagura c. 070 metra supra 

 mare m. Julio a. 1892 c. fr. et inter Bibundi pagum et Bomanam pagum c. 300 metra supra mare 

 m. Decembri a. 1890 c. fr. et Januario a. 1892 c. fr. legi. 



Very common on the west side of the Cameroons Mountain, but not found in the immediate 

 neighbourhood of the sea; appears to tlirive best at a heiglit of 200-800 m. In the dark forest 

 it is green and long and very often fertile, growing rather thinly. In the more open and light 

 eountry it grows much denser, intricate and shorter, is yellowish-brown and usually in a 

 barren state.
