A tree attaining 60 feet in height, and rarely 12 feet in girth. Bark smooth 

 and silvery grey. Branchlets brittle, glabrous. Leaves (Plate 125, fig. 5) alternate, 

 unequally pinnate, 8 to 1 2 inches in length. Leaflets seven to nine, usually alternate ; 

 the terminal one largest, articulate and directed to one side, often broadly rhombic ; 

 the others gradually diminishing in size towards the base of the leaf, 3 to 4 inches 

 long by i^ to 2 inches wide, on stout pubescent petiolules, oval or ovate, entire and 

 non-ciliate in margin ; base broadly cuneate or rounded, apex acuminate ; upper 

 surface light green and glabrous ; lower surface pale green with occasional hairs 

 on the midrib and veins. Rachis of the leaf terete, glabrous, with the base swollen 

 and hollowed out, enclosing the buds, which are usually four, the largest and upper- 

 most one developing, the others minute and rudimentary. 



Flowers in nodding terminal panicles, 10 to 20 inches long, white, with a yellow 

 spot at the base of the standard. Pedicels slender and not grouped in pairs. Calyx 

 canpanulate, enlarged on its upper side ; teeth five, short, obtuse, nearly equal. 

 Corolla papilionaceous with clawed petals ; standard nearly orbicular ; wings oblong 

 and two-auricled at the base ; keel-petals free, oblong, and sub-cordate or two-auricled 

 at the base. Stamens ten, free. Ovary linear, stalked, villose ; ovules numerous.

' Judging from the description, as I have seen no specimens. There are specimens in the Kew Herbarium [Cladrastis, 

 sp. ? Hemsley, yor>. Linn. Soc. (Bot.) xxiii. 20l (1887)) which were collected by Millett, probably in the vicinity of Canton, 

 which are very near to the Loochoo species. 



' This name is adopted as being the first one with a description published under the correct genus.
