 longer, and the leaves larger and thinner.

Camps XI to XIII, 8300 to 10,500 ft. 



Allied to Q. MacGregorii, E. Muell., of British New Guinea, but with much thicker 

 and more rigid leaves and larger sepals. 



Argtrocaltmna, Schum. & Lauterb. 



This genus was founded by Schumann and Lauterbach (Plora der Deutschen Schutz- 

 gebiete in der Siidsee, 336) for a plant obtained in Dutch New Guinea with an inferior 

 two-celled ovary and tbe petals, sepals, and stamens in fours. I add here three others, 

 all of which, though obviously closely allied, have the parts in fives, and a five-celled 

 ovary. Schumann refers the genus to Saxifragacece, but I think this affinity very 

 doubtful. The ovary is distinctly inferior, and much resembles that of the Melastomaceae, 

 especially in A. Jiexuosa, Ridl., which is covered with appressed scale-like trichomes 

 resembling those common in Melastoma. The leaves, however, are always alternate 

 and distinctly thorny along the edge.
