are so small that it is difficult to arrive at certain conclusions regarding their 
nature; it is barely possible that there may be a perianth completely inclosing 
the ovary, but if so there are no visible teeth, and should the plant thus fall into 
another section of the family it is still apparently distinct from anything yet 
described. Further collections in the type locality will decide what its true posi- 
tion may- be. Maoutia reticulata Weddell, from the Mariannes and the Philip- 
pines, collected in the latter by Nee, is known with male flowers only, and from 
the description of the leaves might possibly be this species. 
The inflorescence in some ways suggests rather the Moraceae than the TJrti- 
caceae, but its affinities seem to lie with the latter family.

POLYALTHIA Blume. 
Polyalthia williamsii sp. nov. 
Arbor parva; floribus solitariis-ternis, terminalibus vel rarius axilla- 
ribus ; sepalis 3, valvatis, mitriformibus ; petalis 3, subaequalibus, valvatis, 
subplanibus; staminibus circa 125, connectivo antheras exeedente, folia- 
ceo; carpellis circa 20, ovulis solitariis basilaribus, vel rarius duobus 
superpositis ; foliis alternis, integer ri mis, oblongis ellipticis vel ovatis. 
Flowers solitary or two or three together, terminal or sometimes axil- 
lary, borne on peduncles 7-12 mm long and 1. -1-1.8 mm thick; bracts 
cupular, sheathing the peduncles, 2 mm long, their apices about 1.5 mm 
below base of flowers, abruptly and sharply acuminate at the apex, with 
short and scattered reddish pubescence: sepals 3, valvate, mitriform, 
rounded or very shortly and obtusely acuminate and mucronulate at the 
apex, 6 mm long, 5 mm wide in middle, tapering to 3.5 mm at base, 0.5 
mm thick at the middle of the base, decreasing in thickness upwards and 
outwards, ciliolate, with scattered reddish hairs on the middle of the 
back; jDetals 3, valvate, flat or nearly so, somewhat obliquely oval, 17.5- 
18.5 mm long, 8.5-11.5 mm wide, attached by the somewhat arching- 
base 3-3.5 mm \Vide, not much thickened in the basal 5-6 mm, then 
swollen to a thickness of 1.5—1 mm except at the extreme edges, causing 
them to be sometimes almost triangular in section; stamens about 125 
in number, arranged in 5 or 6 rows, 3.5-1 mm long, 1-1.2 mm wide, 
arching and dehiscing outwards, oblanceolate or narrowly oblong; con- 
nective prolonged beyond the anther-cells for about 0.5-0. 7 mm, foliace- 
ous, rounded at the apex, not as thick as the anther-cells : carpels about 
20, 2.7-3 mm long, 1 mm wide in middle, the densely brown-tomentose 
ovary forming about two-thirds of the entire length, 1-celled, with one 
basal ovule, or in young ovaries apparently a second placed above the 
first but aborting early. 
A small tree about 5.1 m high, with a trunk 6.2 cm in diameter, the 
bark of the ultimate branches greenish- to dark-brown, striate, glabrous: 
leaves alternate, the lamina entire, oblong, elliptic, or ovate, borne on 
petioles 5.5-11 mm long, acute or obtuse at the base, obtusely acuminate
