Common in the Happy Valley, Champion; also Wright, and in S. China, Reeves. Be- 

 sides the much larger flowers and usually broader leaves, this appears to differ from the more 

 common A. agallochum in the shape of the ovary, in the less woody capsule, and in the form 

 of the appendage to the seed. I had considered that it might be the A. malaccensis, Lam. ; 

 but I have since seen Malacca specimens of what is more probably that plant, and which 

 appears to be only a broad-leaved variety of A. agallochum. 



Order XCII. EL^AGNACE^l. 



Perianth tubular, free but persistent at the base, and contracted above the 

 ovary, the upper portion deciduous and 2- or 4-lobed. Stamens equal to 

 and alternate with the perianth-lobes or twice as many, inserted in the tube 

 Or at its base. Anthers 2-celled, opening longitudinally. Ovary 1 -celled, 

 with 1 erect ovule. Fruit indehiscent, usually succulent, enclosed in the 

 persistent base of the perianth. Seed with a very thin or without albumen. 

 Embryo straight, the radicle inferior. — Trees or shrubs, more or less covered 

 with scurfy stellate scales. Flowers in axillary clusters or cymes. 



A small Order, chiefly Asiatic or European, with a very few American species.

1. E. Loureiri, Champ, in Keio Journ. Bot. v. 196. A shrub, without 

 any of the thorns so common in the genus, the rusty-brown scurfy scales 

 abundant on the young branches, the under side of the leaves, and especially 

 on the flowers. Leaves ovate or oval-oblong, obtuse or acute, \\ to 3 in. 

 long, glabrous above. Flowers usually 2 or 3 together, in lateral clusters or 

 short racemes. Lower portion of the perianth enclosing the ovary, ovoid, 1^ 

 to 2 lines long when in flower, 7 or 8 lines long and 4-angled or winged 

 when in fruit, upper deciduous portion campanulate, 8 or 9 lines long, neither 

 angular nor constricted under the lobes, which are lanceolate, about 3 lines 

 long. Fruit slightly succulent ; the endocarp very tough and filamentous.

On Mounts Parker and Gough, Champion; in woods at Little Hongkong, Wilford ; also 

 Wright. Not known out of the island.

 them, inserted at their base or within the free part of the tube. Anthers 2- 

 celled, opening longitudinally. Ovary inferior, 1-celled, with 3 to 5 ovules 

 suspended from a free erect placenta. Fruit an indehiscent nut or berry, with
