122 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
to 85 in., breadth 1°8 to 3 in.; petiole *35 to ‘5 in., rusty-pubescent. Flowers poly- 
gamous, extra-axillary, solitary or 2 or 3 together, sub-globose, from ‘5 to ‘75 in. in 
diam.; pedicels stout, tomentose, 15 to ‘25 in. long, with 2 bracts nearly as large ‘as the 
sepals. Sepals ovate-orbicular, acute, slightly smaller than the outer petals, very thick, 
villous-tomentose outside and glabrous inside as are all the petals; imner petals larger 
than the outer, their apices much inflexed in bud. Stamens numerous, with flat, 
rhomboid heads. . Ovaries numerous, hirsute. Carpels numerous, cylindric ovoid, apiculate, 
narrowed to the stalk, sparsely strigose, °5 i. long and ‘25 im. in diam.; stalks °2 to °3 
in. long, strigose-pubescent. Torus globular, °4 in. in diam. Seed pale, shining. King in

12. Porowra Kurzu, King in Journ. As. Soc. Bengal 61, pt.'2, 96. A shrub or 
small tree; young branches at first tawny-pubescent, .afterwards dark-coloured, glabrous 
and furrowed. Leaves sub-coriaceous, oblong-lanceolate or elliptic-oblong, sub-acute, or 
shortly and bluntly acuminate, narrowed to the sub-cuneate (sometimes almost rounded) 
base; upper surface sub-granular, minutely and sparsely adpressed-pubescent; lower 
sparsely pubescent; main nerves 9 to 12 pairs, oblique, inter-arching close to the edge, 
rather prominent beneath; length 5 to 9 in., breadth 1:5 to 8 im.; petiole -2 to -25 
in., tomentose. Flowers polygamous, solitary, or in pairs, sub-sessile, extra-axillary, sub- 
globose, *4 in. in, diam.; pedicels tomentose, *1 to ‘2 in. long, bracteolate. Sepals smaller 
than the petals, valvate, semi-orbicular and, like the petals, tomentose externally and 
glabrous internally. Petals sub-equal, concave; the outer ovate-orbicular, valvate; the 
inner slightly smaller than the outer, imbricate. Stamens numerous, flattened, elongate, 
with linear lateral anther-cells and flat, oblique, rhomboid apices. Ovaries (often absent) 
about 10, elongate, pubescent; the stigmas clavate. Fruit unknown. Polyalthia macro-

This species appears to be practically dicecious. In its flowers the inner petals are 
distinctly imbricate; they are not connivent, and 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 (F\. Jay. Anon. 96, t. 47), and to receive which Miquel founded his genus 
Trivalvaria (Ann. Mus. Lugd. Bat. ii. 19). But 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 fails to conform to the HOG Ns of, the genus Popowia as 
a defined by its founder Endlicher, 7
