their points are not inflexed. And in these respects they do not answer 

 to the diagnosis of Popowia as heretofore understood. I have therefore 

 ventured to modify the generic character of Popowia in these points, and 

 to institute a section of it to receive this and other two species. This 

 species is closely allied to the plant originally described and figured 

 by Blume as Guatteria macrophylla, (Fl. Jav. Anon. 96 t. 47,) and to 

 receive which Miquel founded his genus Trivalvaria (Ann. Mus. Lugd. 

 Bat. II, 19). Bat, in Blume's and Miquel's plant, the inner petals are 

 distinctly valvate, although their apices are not inflexed. And in the 

 non-inflection of its petals it also does not conform to the character of 

 Popowia as originally defined by its founder Endlicher. 



12. Popowia Hookeri, King. A shrub ; young branches dark- 

 coloured, glabrous. Leaves thinly coriaceous, broadly lanceolate or 

 oblanceolate, acute or acuminate, the base acute : both surfaces glabrous, 

 the lower silvery, shining : main nerves about 7 pairs, spreading, 

 ascending, curving, rather prominent beneath, evanescent at the tips ; 

 length 5"5 to 7 in., breadth 1*6 to 2 - 4 in. Floivers solitary or in fascicles 

 of 2 or 3 from short extra-axillary, woody tubercles, polygamous, minute ; 

 " the males as in Popowia Kurzii but smaller ; the females with many, 

 densely pubescent ovaries and a few imperfect stamens ; bracts many, 

 minute, strigose. Carpels many, "75 in. long, oblong, granulate, glabrous ; 

 stalk -35 in." Guatteria pallida, H. f. and Th. Fl. Ind., 143 (not of 

 Blume). Polyalthia argentea, Hook. fil. and Thorns. Fl. Br. Ind. I, 67. 



Assam and Sylhet ; in dense forests, Hook. fil. and Thomson ; Naga 

 Hills, Masters. Khasia : Griffith. 



A species of which I have seen only imperfect specimens. The 

 description given above of the flowers is copied from Sir Joseph Hooker. 

 In my opinion the plant is a Popowia rather than a Polyalthia and to 

 the former genus I have ventured to remove it. 



Doubtful Species. 

 Popoivia parvifolia, Kurz in Journ. of Botany for 1875, p. 324. Of 

 this I have seen only leaf specimens -with a few detached fruits. It ap- 

 pears to have also had the MSS. name P. nitida given to it by Kurz. 



18. Oxtmitra, Blume. 

 Climbing shrubs. Leaves parallel-nerved ; nervules transverse, not 

 forming intra-marginal loops. Floivers leaf-opposed or extra- axillary. 

 Sepals 3, valvate, connate below. Petals 6, valvate, in 2 rows, outer 

 large, long, flat or triquetrous and narrow, leathery, more or less spread- 

 ing or connivent ; inner much smaller, ovate-lanceolate or oblong (lono- 

 and narrow in 0. filipes and 0. glatica), conniving over the stamens and
