rior or ^-inferior, enclosed in the calyx-tube, usually with many ovules in each 

 cell. Capsule opening- loculicidally from above by 3 valves. Perfect seeds 

 cuneate ; embryo straight, cotyledons longer than the radicle. DISTKIB. Up- 

 wards of 100 species, all Australian, one of them extending into Tropical 

 Asia. 



1. M. ILeucadendron, Linn. ; leaves alternate elliptic or lanceolate 

 straight oblique or falcate 3-7-nerved with anastomosing nerves, spikes long 

 interrupted solitary or 2 or 3 together terminal at first and then surmounted 

 by leafy branches, rachis and calyx glabrous or woollv. Benth. Fl. Austrrl.

TENASSERIM and MEBGUI, Griffith; MALACCA, Maingay> Cuming. DISTEIB. Malay 

 Islands to Australia. 



A tree, often of large size, with a thick spongy bark peeling off in layers, and 

 pendulous branches ; or stunted and with stiff erect branches. Leaves often vertical, 

 acuminate acute or obtuse, narrow and 6-8 in., or broader more rigid and 2-4 in* 

 Flower-spikes 2-6 in. Calyx-tube ovoid ;, lobes roundish and often scarious at the 

 margin. Petals ^ in. Staminal bundles under in., each with 5-8 filaments. 

 Ovules oo, ascending, attached to an oblong placenta. Fruiting-calyx about | in. in 

 diam. Seeds obovoid or cuneate ; cotyledons obovate, thick, much longer than the 

 radicle. 



The following are the principal varieties of this species, concerning which Mr. 

 Bentham remarks (Fl. Austral, iii. 142) : " This species, very widely spread and 

 abundant in the Indian Archipelago and Malayan Peninsula, varies exceedingly in the 

 size, shape and texture of the leaves, in the young shoots very silky- villous or woolly, 

 or the whole quite glabrous ; in the short and dense or long and interrupted spikes ; 

 in the size of the flowers ; in the greenish -yellow, whitish, pink or purple stamens, etc.. 

 and at first sight it is difficult to believe that they all can be forms of one species ; but 

 on examination none of these variations are sufficiently constant or so combined as to 

 allow of distinct races."

Miquel(Fl. Ind. Bat. 1. c.) describes M. Cumingiana as specifically distinct, distin- 

 guishing it from M. lancifolia by the absence of auricles to the staminal bundles ; the 

 existence of these however in the latter does not appear to be evident. Mr. Bentham 

 (Fl. Austral. 1. c.) considers that both of them belong to one of the common Archipe- 

 lago forms with twin leaves and small flowers. 



4. TRISTANIA, R. Br. 



Tall shrubs or trees. Leaves alternate or crowded at the summit of the 

 branches, rarely opposite. Flowers small, yellow or white, arranged in axillary 

 cymes; bracts deciduous or 0. Calyx-tube turbinate campanulate or open, 

 attached below to the ovary ; lobes 5, imbricate in aestivation, persistent. Petals
