free ; segments 10-15, thick, linear. Petals as many, 2-lobed. Stamens 

 twice the number of petals ; anthers Hnear, 2-celled, mucronate, about as 

 long as filaments. Ovary inferior, included in calyx-tube, 2-4-celled, with 

 2 pendulous ovules in each cell ; style filiform, with 2-4 minute stigmatic 

 lobes. Fruit turbinate, crowned by the persistent calyx-lobes. Germin- 

 ation as in Rhizcrphora.

 i^A large evergreen tree, with oblong-eUiptical, short-acuminate leaves 

 3-6 in. long, 1^-2J in. broad, narrowed into a petiole about 1 in. long. 

 Stipules oblong, 1-2 in. long, very deciduous. Flowers solitary, about 1 

 in! long. Calyx thick and rigid, lobes usually about 12, the tube about 

 ^ the whole length. Petals shorter than calyx, deeply 2-lobed, densely 

 hairy at the base ; margins induplicate, more or less hairy all the way 

 up ; setse usually 1 in the notch and 3-4 at the end of each lobe. Anthers 

 embraced in pairs by the induplicate edges of the petals. Fruit at first 

 crowned by the calyx-limb, which often falls off as the radicle protrudes, 

 the latter assuming a narrow spindle-shaped form, with about 6 promi- 

 nent angles. 



Sindh, estuary of the Indus. Coast of Peniuaula, Sundarbans. Indian 

 Archipelago. North Australia. Wood yellowish brown, hard and durable. 

 This tree sends down numerous roots from the trunk and branches, which 

 eventually raise the stem, so that it appears divided before it reaches the ground. 

 Rkizophora mucronata and other Mangroves do the same. Griffith (on the 

 family of the Rhizophorese, Transactions of the Medical and Physical Society 

 of Calcutta, viii. 6) ascribes the lifting up of the stem to the resistance 

 which the roots meet at their extremities. Nearly aUied to this, and probably 

 a variety only, is —

 t. 641, — ^with large soHtary ilowers, calyx-lobes 8-12, margin of petals from 

 base to apex densely hirsute. 



Three other Indian species enumerated in Wight's lU. p. 210, differ from 

 B. gymnorhiza by smaller flowers in axillary, pedunculate 2-to many-flowered 

 cymes ; they are small glossy trees closely allied to each other, and probably 

 form one species only. 1. B. caryophylloides, Blume {Rhiz. caryophyllcddes,

4. CABALLIA, Eoxb. 



Trees and shrubs, wholly glabrous, with small flowers in pedunculate, 

 compact trichotomous cymes. Calyx-tube campanulate, produced beyond 

 the ovary, with 5-8 short segments. Petals as many as calyx-segments, 

 TiDguiculate, orbiculate, serrate or laciniate. Stamens twice the number 

 of petals, inserted on the crenulate edge of the disc, which clothes the 

 calyx-tube. Ovary adnate to calyx, generally 4-celled ; ovules 2 in each 

 cell. Embryo terete in a copious albumen.
