74 Materials for a Flura of Ihe Malayan Peninsula. 



Under his species A. cordata, Mr. Hieru has in my opinion included 

 two plants. The species A. cordata, as here limited, includes only Hiern's 

 foim with hirsute calyx, and is really little more than a large-leaved 

 variety of A. palemhanica. Mr. Hiern's form with glabrous calyx is, in 

 my opinion, a distinct species, the calyx differing not only in being 

 glabi'ous, but in being much smaller, and of quite a different shape. 

 1 have described it as a species under the name A. Hiernii. 



20. Aglaia Hiernii, King, n. sp. A tree 40 to 80 feet high ; 

 young branches, petioles, rachises, petiolules and inflorescences, densely 

 clothed with rather soft rusty stellate tomentum. Leaves 14 to 18 in. 

 long, unequally pinnate ; leaflets 7 to 9, the pairs opposite, thickly mem- 

 branous, oblong or oblong-lanceolate ; the terminal one oblong-oblanceo- 

 late, longer than the others and two or three times as long as the 

 petiolule ; the apices of all shortly and sharply acuminate, the bases 

 cuneate, especially of the uppermost ones ; upper surface glabrescent 

 with a few scattered stellate-hairs, the midrib and nerves densely 

 stellate-pubescent; under-surface uniformly covered with pale-brown- 

 centred scales and a superficial layer of rufous stellate tomentum ; main 

 nerves 13 to 22 pairs, sub-horizontal, depressed on the upper and bold 

 on the lower surface when dry ; length 4 to 6 in. (the odd one an inch 

 longer); breadth 175 to 2'25 in., petiolules of the pairs '15 in. 

 Panicles slightly supra-axillary, solitary, 8 to 12 in. long, the branches 

 divaricating, the ultimate branchlets bearing densely-flowered spikes. 

 Flowers '4 in. long, sessile, globular. Calyx cupular, quite glabrous, 

 with 4 or 5 deep broad rounded imbricate lobes. Petals 5, rotund or 

 ovate-rotund, unequal, much longer than the calyx, the outer 3 the largest, 

 all concave and glabrous. Staviinal tube shorter than the petals, cup- 

 shaped, the mouth wide ; the 5 ovate anthers inserted by vei-y short 

 filaments on the edge of the tube, but inflexed so as to be included. 

 Ovary small, pubescent ; stigma depressed-spheroidal, pubescent. Fruit 

 unknown.

This is allied to A. cordata, Hiern, but differs from it in having lea- 

 flets with more numerous and more horizontal main nerves, more densely 

 toraentose and lepidote beneath. The calyx of this, moreover, is con- 

 spicuously different, being smaller, having broad lobes much shorter 

 than the petals, and quite glabrous, while the calyx of A. curdata, as 

 limited here, has a large calyx densely stellate-tomentose externally, and 

 with acute lobes often longer than the petals. This is a large tree, 

 often attaining a height of 80 feet, while A. cordaca is a small tree from 

 20 to 30 feet high.
