MELIACEAE 
AGLAIA Loureiro 
AGLAIA MARIANNENSIS sp. nov. § Euaglaia. 
Arbor 5 ad 7 m alta, partibus junioribus inflorescentiisque 
dense ferrugineo-lepidotis, vetustioribus subglabris; foliis 20 ad 
30 cm longis, foliolis 5 ad 9, oblongis ad oblongo-ellipticis, usque 
ad 15 cm longis, acutis vel obscure acuminatis, basi acutis ad 
rotundatis, vetustioribus subglabris vel subtus obscurissime 
lepidotis ; paniculis folia subaequantibus ; floribus 5-meris, 
numerosis, racemose dispositis, breviter pedicellatis, tubus stam- 
ineus liber. 
A tree 5 to 7 m high, the young branchlets, leaves, and inflo- 
rescence for the most part densely brown-lepidote. Branches 
about 5 mm in diameter, terete, grayish or brownish, glabrous, 
the petiolar scars scattered, large, the growing parts densely 
brown-lepidote. Leaves alternate, 20 to 30 cm long, mostly 3- 
jugate, sometimes with two pairs of leaflets, sometimes with 4 
pairs, besides the terminal leaflet, the petiole and rachis lepidote, 
becoming nearly glabrous. Leaflets oblong to oblong-elliptic, 
10 to 15 cm long, 3 to 6 cm wide, chartaceous, when very young 
somewhat lepidote, in age becoming glabrous or nearly so, a few 
prominent scales usually persisting on the midrib and lateral 
nerves, the lower surface sometimes very minutely cinereous- 
subfurfuraceous, paler than the upper one, the apex acute or 
somewhat acuminate, the base acute to rounded, often inequilat- 
eral; lateral nerves 10 to 14 on each side of the midrib, distinct; 
petiolules 7 to 10 mm long. Panicles in the upper axils, narrowly 
pyramidal, often as long as the leaves, always more than one-half 
as long, all parts rather densely brown-lepidote. Flowers nu- 
merous, racemosely arranged on the ultimate branchlets, their 
pedicels 0.5 to 1.5 mm long. Calyx brown-stellate-lepidote, the 
lobes 5, oblong-ovate, acute, 1 to 1.2 mm long. Petals 5, gla- 
brous, orbicular to obovate, concave, 1 to 1.5 in diameter. Sta- 
minal tube quite frse from the petals, very shallowly cup-shaped, 
glabrous, about 1 mm in diameter, 0.5 mm high, obscurely 5- 
toothed. Stamens 5, alternating with the teeth of the staminal 
tube, protruded, the anthers about 0.3 mm long. Fruit ellip- 
soid to obovoid, densely brown-stellate-lepidote, about 1.5 cm 
long and nearly as thick. 
Guam Experiment Station 465, July, 1912 (type), McGregor 546, October, 
1911, Airs. Clemens s. n., November, 1911, locally known as mapunao. 
A species apparently closely allied to the Malayan Aglaia adoratissima 
Blume, which it greatly resembles in appearance and vegetative characters. 
The very shallow staminal tube is apparently characteristic.
