23. PoLyALTHIA HypocmA, Aing tr Journ. As. Soc. Bengal 61, pt. 2, 62. <A tree 
25 to 30 feet high; young branches rather stout, densely but minutely rufous-tomen- 
tose, ultimately rather pale, striate. eaves large, thinly coriaceous, oblong, or elliptic- 
oblong, sometimes slightly obovate, gradually narrowed to the rounded base; both 
surfaces glabrous when adult; the lower puberulous when young, the veins transverse 
and (like the reticulations) distinct; main nerves 18 to 22 pairs, oblique, inter-arching 
within the edge, thin, prominent on the lower and depressed on the upper surface 
when dry; length lv to 20 in., breadth 3 to 7 in.; petiole ‘4 in., stout, tomentose. 
Fiowering branches from the stem near its base, 1 to 8 feet long, flexuose, rufous- 
pubescent’ like the lanceolate bracteoles. Fvowers ‘75 to 1 in. long, cream-coloured ; 
pedicels ‘75 to 1:5 in. long, usually with one lanceolate tomentose bracteole near 
the middle, and a second, sub-orbicular and acuminate, close to the flower. Spas 
broadly © triangular-ovate, acute, spreading, tomentose outside, glabrous inside, *25 in. 
long. Petals coriaceous, the inner row rather smaller than the outer, narrowly oblong, 
sub acute, pubescent outside except the glabrescent base and edges, inside almost 
glabrous. Stamens numerous, short, compressed; apical process of connective broad, 
slightly convex, slightly oblique, sub-granular, deeply ridged in front, the anther-cells 
linear, dorsal. Ovaries few, oblong, villous, l-ovuled; stigma large, ovoid, granular, 
sessile. Immature carpels narrowly ovoid, sub-compressed, the spex beaked, the base 
slightly contracted, minutely tomentose, Seed solitary, elongated, ovoid, smooth.

A species remarkable for its hypogmzal inflorescence. The flowering branches, 
which vary from 1 to 8 feet in length, originate from the stem near its base, 
pass into the soil underneath the surface of which they run for some distance, and 
bear on their emerging tips the flowers and fruit.

26. PotyatTHIA  opiiqua, Hook. fil. § Thoms. Fl. Ind. 138. A tree; young 
branches minutely pubescent, lenticellate. eaves sub-sessile, oblong-lanceolate, acute or 
shortly acuminate; the base cuneate, minutely and obliquely cordate, shining and 
glabrous on both surfaces, the lower pale; main nerves 7 or 8 pairs, slender, curving 
and forming bold arches *15 in. from the margin; length 4 to 6°5 in., breadth 1:5 
to 2:2 in.; petiole +1 in., very stout. Flowers 4 to 4:5 in. in diam., solitary, pedi- 
cellate, extra-axillary ; each pedicel rising from a short, conical, woody tubercle, curving, 
‘25 in. long. | Sepals coriaceous, broadly triangular, blunt, less than half as long as 
the petals, pubescent. Petals coriaceous, sub-equal, oblong, obtuse, sericeous outside.
