150 Rhizopkoracece . \RMzophora. 



Upper montane zone ; a common weed on damp ground or mud. Fl. 

 all the year. 



Found in most parts of the Old World, temperate and Tropical. The 

 Ceylon plant is somewhat smaller than the common English form, and 

 has a rather narrower wing to the fruit. 



L.— RHIZOPHORACE^E. 



TREES or shrubs, 1. opp., with large interpetiolar stip. (alt. and 



without stip. in Anisophyllea), entire, glabrous ; fl. regular, 



bisexual ; cal. more or less adnate to ov. (free in Weihea), 



segm. 4, 5, or 8-14, valvate; pet. same number as cal.-segm., 



often cut or laciniate; stam. double number of pet. (in Weihea 



more) perigynous or epigynous (hypogynous in Weihea) ; disk 



annular and lobed or absent ; ov. inferior or half-inferior 



(superior in Weihea), 2-4-celled, with 2 (1 in Anisophyllea) 



pendulous ovules in each cell ; fruit leathery, indehiscent, 



i-seeded (dehiscent and with 4-6 seeds in Weihea) ; seed 



usually with a large macropodous embryo without endosperm, 



sometimes with a small embryo in axis of copious endosperm. 



L. opp., with interpetiolar stip. 

 Seed without endosperm, embryo germinating in 

 the fruit {Rhizophorece). 



Pet. 4, ov. ^-inferior 1. RHIZOPHORA. 



Pet. 5, ov. ^-inferior 2. CERIOPS. 



Pet. 8-14, ov. quite inferior . . . .3. BRUGUIERIA. 



Seed with fleshy endosperm (Legnotidece). 



Ov. inferior 4. CARALLIA. 



Ov. superior 5. Weihea. 



L. alt., without stip. Seed without endosperm (Ani- 

 sophyllea?) 6. ANISOPHYLLEA. 



The tribe Rhizophorecs are the true Mangroves, and our 6 species are 

 found in suitable places all round the coast of the island. Of the rest, 

 the endemic Carallia calycina is nearly restricted to the lower montane 

 zone; Weihea and Anisophyllea are low-country plants, and the latter is 

 confined to the moist region. 



1. RHIZOPHOBA, L. 



Moderate-sized trees, sending down numerous aerial roots 

 from the stem and branches, 1. opp. entire, thick, with large 

 interpetiolar deciduous stip. enclosing the buds, fl. in pairs, 

 each supported by 2 hard thick fused bracts ; cal. very deeply
