Of this very curious endemic Proteaceous tree Mr. Baron has 

 now (No. 3253) procured complete specimens, from which the 

 following notes are taken. Dr. Baillon has recently described 

 it fully in the Bulletin of the Linnean Society of Paris, p. 391, 

 from specimens gathered in the north-west of the island by 

 M. Humblot. 



A large tree with thick terete branchlets, coated with brown 

 tomentum. Leaves alternate, rigidly coriaceous, glabrous ; blade 

 cuneate, deeply bifid, | ft. long and broad, the apical lobes semi- 

 orbicular and simple in the mature leaf, prolonged and agaiu 

 forked in the young leaves ; petiole 3-4 in. long, flattened and 

 winged towards the top. Flowers dioecious, arranged in copious 

 ascending axillary panicles about as long as the petiole, with a 

 tomentose axis and branchlets ; branchlets laxly spicate, each 

 flower subtended by a minute ovate bract. Male perianth clavate, 

 ^ in. long, slit down to the base into four lanceolate valvate 

 segments, glabrous inside. Stamens a little shorter than the 

 perianth-segments ; anther ± in. long, tipped with the pro- 

 truded connective, much longer than the fleshy cylindrical fila- 

 ment. Female panicle shorter and less compound than the male. 

 Ovary globose, densely ferruginous, with a short thick style and 

 2-lobed stigma. Fruit hard, thick, 1-seeded, indehiscent, oblong, 

 1$ in. long. Native name Vivaona. The plant gathered by 

 Dr. Parker, mentioned in Journ. Bot. 1882, p. 244, is a form of 

 the same species.

A shrub, with compressed woody branchlets with two raised 

 angles, falling in pieces readily at the nodes, with mternodes |-1 

 in. long. Leaves very thick and rigid in texture, 2-3 in. long, 

 opaque, brown and quite glabrous on both surfaces when dried, 

 rounded to a cuneate base. Flowers few in a cluster, quite sessile
