2. LUMNITZERA, Willd. 
(After Stephen Lumnitzer.) 
Calyx-tube produced above the ovai’y but scarcely contracted, the limb cam- 
panulate, shortly 5-lobed or 5-toothed. Petals 5, spreading. Stamens 10 or 
fewer. Ovules 2 to 5 ; style filiform, with a minute stigma. Fruit ovoid-oblong, 
crowned by the persistent calyx, narrowed and flattened at the base, hard and 
almost woody. Seed linear, with convolute cotyledons. — -Maritime trees or 
shrubs. Leaves crowded at the ends of the branches, obovate or cuneate, thick, 
entire or slightly crenate. Flowers in short racemes. Bracteoles 2, adnate to 
the base of the calyx-tube, persistent but not enlarged after flowering. 
The genus is limited to a few species. The two following are widely dispersed along the 
seacoasts of tropical Asia, extending from E. Africa to the Pacific Islands. — Benth. 
Flowers scarlet, in terminal racemes. Calyx fully Jin. long. Stamens twice as 
long as the petals 1. L. coccinea. 
Flowers white, in axillary racemes. Calyx about 4 lines long. Stamens 
scarcely exceeding the petals 2. L. racemosa. 
1. L. COCCinea (scarlet flowers), W. and Am. Prod. 816; Bentli. FI. Austr. 
ii. 508. A glabrous bushy shrub or small tree. Leaves obovate or oblong- 
cuneate, very obtuse, often 2in. long, thick and fleshy. Flowers scarlet, in dense 
terminal racemes, of which occasionally 2 or 3 form a small corymb. Calyx in 
the Australian specimens fully Jin. long at the time of flowering, continuous with 
and narrowed into a somewhat flattened pedicel of 2 or 3 lines ; lobes of the limb 
short, broad and obtuse. Petals exceeding the calyx-lobes by about 2 lines ; 
stamens twice as long. Fruiting-calyx above lin. long. 
Hab.: Endeavour River, Banks and Solander ; edges of mangrove swamps, from Rockingham 
Bay to Cape York. 
We have precisely the same form from the Fiji Islands; the common Malayan specimens 
have usually rather smaller specimens. — Bentli. 
2. I., racemosa (flowers in racemes), Willd.; DC. Prod. iii. 22 ; Benth. FI. 
Austr. ii. 504. A glabrous tree or tall shrub, with the foliage of L. coccinea, but 
the racemes are all axillary, usually about as long as the leaves, and the flowers 
are smaller and white. Calyx at the time of flowering about 4 lines long, and 
not above Jin. when in fruit, the lobes or teeth very short. Petals about 1J line 
long, and the stamens very little longer. 
Hab.: Islands of the Gulf of Carpentaria, R. Brown, Henne ; Cairncross Island, Torres 
Straits, M-Gillivray, Henne; Fitzroy River and near Keppel Bay, Thozet. 
This appears to be the commonest of the two species on the coasts of tropical Asia. — Benth. 
Wood of a pinkish-grey colour, hard, and close in the grain. — Bailey's Cat. Ql. Woods No. 164. 
3. MACROPTERANTHES, F. v. Muell. 
(Referring to the prominent wings of the calyx.) 
Calyx-tube produced above the ovary and scarcely contracted, the limb rather 
broader, shortly 5-lobed or 5-toothed. Petals 5. Stamens 10 or fewer. Ovules 
10 to 12, pendulous ; style filiform, with a minute stigma. Fruit (oblong ?) 
small trees. Leaves opposite or clustered at the nodes, small obovate or 
crowned by the persistent calyx. — Silky- white or tomentose shrubs or 
oblong, entire. Flowers in pairs on axillary (or terminal ?) peduncles. Bracteoles 
adnate in the centre to the base of tbe calyx ; the margins free, much enlarged 
after flowering, forming wings to the fruiting calyx. 
The genus is endemic in Australia. It is very closely allied to Lumnitzera, differing in the 
wings of the fruiting-calyx and in the number of ovules, and the species are not strictly 
maritime. — Benth,
