FLORAL DEVELOPMENT IN MANGROVE RHIZOPHORACEAE
American Journal of Botany, 1987The flowers of mangrove Rhizophoraceae (tribe Rhizophoreae) are adapted to three different pollination mechanisms. Floral development of representative species of all four genera suggests that the ancestral flower of the tribe was unspecialized, with successively initiated whorls of separate sepals, petals, antisepalous stamens, and antipetalous ...

Bijugate phyllotaxis in Rhizophoreae (Rhizophoraceae)
Botanical Journal of the Linnean Society, 1979Phyllotaxis in the mangrove genera of Rhizophoraceae is shown to be bijugate, the angle between orthostichies always less than 90d and in some species close to one half the Fibonacci angle (68.8d). The same leaf arrangement occurs in both orthotropic shoots with extended internodes and in the crowded terminal rosettes of those branches which develop ...

Rhizophoraceae alkaloids. Part II. Gerrardine
Journal of the Chemical Society C: Organic, 1967The mass spectrum of gerrardine, C11H19NO2S4, showed a molecular ion species corresponding to (C8H14NOS2)+, and Raney nickel desulphurisation gave a compound, C10H22O2, m. p. 33°, considered as decane-2,9-diol. The structure for the alkaloid is deduced as 1-methyl-2,5-bis-(4-hydroxy-1,2-dithiolan-3-yl)pyrrolidine.

THE GENUS CARALLIA (RHIZOPHORACEAE) IN CEYLON
Acta Botanica Neerlandica, 1982SUMMARY Apart from the common Carallia brachiata (Lour.) Merr. and the rare C. calycina Benth. (reduced by Ding Hou, but re-instated correctly by Macnae & Fosberg), two further Ceylonese species are described: C. orophila sp. nov. (based on C. calycina var. b. Thw.) and C. paucinervia sp. nov.

Rhizophoraceae alkaloids. Part III. Cassipourine
Journal of the Chemical Society C: Organic, 1967Cassipourine, C14H22N2S4, a ditertiary base, gives pyrrolo[1,2-a]pyrrolidine by zinc-dust distillation, and pyrrolizidine by desulphurisation with Raney nickel. Oxidation of cassipourine with hydrogen peroxide gives the di-N-oxide and with concentrated nitric acid pyrrolizidine disulphonic acid N-oxide.

Sylleptic Branching in the Rhizophoreae of the Rhizophoraceae
Botanical Gazette, 1981Multiple axillary buds occur in all genera of mangrove Rhizophoreae (Rhizophora, Bruguiera, Ceriops, and Kandelia). In normal development, the upper, larger, first-formed bud ("principal bud") of all of the examined species yielded only a sylleptic branch. Only the smaller, lower "subordinate" bud could yield a flower or inflorescence.

Distribution and Rarity of Rhizophoraceae in Peninsular Malaysia
2013This paper attempts to review the distributions and rarity of Rhizophoraceae in Peninsular Malaysia. Results presented were from plot studies (11 sites), random field surveys (3 sites) and previously published reports. The primary data were from four sites in Johor (Belungkor Forest Reserve, Pulai Forest Reserve, Santi Forest Reserve and Tanjung Piai),

Cytogenetics and reproductive biology of mangroves in Rhizophoraceae
Australian Journal of Botany, 2002Three mangrove species, Bruguiera gymnorrhiza (L.) Lam., Rhizophora samoensis (Hochr.) Salvoza, Rhizophora stylosa Griff. and a putative hybrid Rhizophora × selala (Salvoza) between the latter two species were studied for their cytogenetics and reproductive biology.
