flr. is dioecious and anemophilous, but is sometimes $ and protandrous, 
and is said to be visited by flies.

Enhalus Rich. Hydrocharitaceae. r sp. Indo-mal., living in salt 
water. The $ firs, float horizontally at low water, and catch the 
<? firs., which (as in Vallisneria) break off and float. As the tide 
rises, the ? firs, stand vertically, and the pollen, which is heavier 
than water, sinks down upon the stigmas. The testa bursts when 
the seed is ripe, and the young embryo is freed (Svedelius, Ann . 
Perad ., II. 267).

Epacridaceae. Dicotyledons (Sympet. Ericales). 21 gen. with about 
320 sp., found chiefly in Austr. and Tasmania, where they represent 
the Ericaceae of other continents, but extending also to India, N. Z., 
and S. Am. They resemble the Ericaceae (sect. IV.) closely in habit 
and appearance, being mostly small shrubs, sparingly branched, with 
narrow, entire, rigid leaves, usually alternate. Sometimes the leaves 
are sheathing, in which cases either no scar is left on the stem when 
the leaf falls, or a ring mark is left, as in Dracophyllum. The firs, are 
usually in terminal racemes or spikes, g > actinomorphic. K5, C (5), 
A 5, hypogynous at edge of disc, or more often epipetalous; the anthers 
opening by one central longitudinal slit and without horns or other 
appendages; pollen simple or in tetrads. G(5) cpls. opposite petals, 
placentae axile; ovules in each loc. 1 — co , anatropous, usually pendu- 
lous. Style simple, sometimes in depression of top of ovary, with a 
capitate stigma. Fruit a capsule or stony drupe. Embryo straight, in 
copious endosperm. Chief genera : Sprengelia, Richea, Draco- 
phyllum, Epacris, Styphelia. Placed in Ericales by Benth. -Hooker, 
in Bicornes by Warming.

They are much cultivated in greenhouses for their firs.
