branches, large, not dotted. Calyx often nearly valvate. 
Stamens all perfect. Fruit angular, fibrous, with a single seed 30. Barringtonia.

not angular, fleshy, with several seeds enveloped in pulp 31. Cakeya. 
1. DARWINIA, Rudge. 
(After Dr. Darwin.) 
(Genetyllis, DC.; Hedaroma, Lindl.; Polyzone, Endl.; Schuermannia, F. v. M.; 
Cryptostemon, F. v. M.; Franciscia, Endl.) 
Calyx-tube nearly cylindrical, turbinate or hemispherical, the lower adnate 
part more or less distinctly 5 or rarely 10-ribbed, the upper disk-bearing free 
portion scarcely ribbed ; lobes 5, scarious or petal-like, often very minute. 
Petals 5, entire. Stamens 10, alternating with as many staminodia, very 
shortly united at the base in a single ring, or rarely the staminodia when broad 
forming an outer row ; anthers globular, opening in 2 minute pores near the 
scarcely prominent connective. Ovary 1 -celled, with 2, 3, and very rarely 
(except in D. micropetala, a South Australian species) 4 ovules, inserted 
on a very short basal, usually excentric placenta. Style exserted, usually 
long, and more or less bearded towards the end ; stigma terminal, minute 
or capitate. Fruit formed of the slightly-enlarged and somewhat hardened 
calyx. Seed usually solitary, filling the fruit, testa very thin. Embryo con- 
sisting of a homogeneous mass or thick radicle of the shape of the seed, 
with a rather slender neck lying along the flattened apex, entire, or perhaps 
divided at the point into two minute cotyledons. — Shrubs with usually a heath- 
like or Diosma- like habit. Leaves small, opposite or scattered, entire. Flowers 
small, nearly sessile, or shortly pedicellate in the upper axils, or in terminal 
heads, the floral leaves or bracts either large and coloured, or small like the 
stem-leaves. Bracteoles thin and scarious, concave, and keeled, enclosing the 
young bud, and very deciduous, or small, narrow, and more persistent. 
The genus is limited to Australia. 
Section I. Genetyllis. — Calyx-lobes not exceeding half the length of the petals, and often 
very minute. Flowers in single terminal heads, rarely becoming lateral by the elongation of the 
central axis. — Benth. 
Leaves crowded, not opposite, semiterete or triquetrous. Flowers sessile or 
nearly so, in terminal heads. Calyx 5-ribbed, otherwise smooth .... 1. D. fascicularis. 
Section II. Schuermannia, F. v. M. — Calyx-lobes as long as the petals, or longer. 
Flowers in the axils of the upper leaves, few or forming compound heads or corymbs, or rarely 
simple. 
Flowers few in the upper axils. Calyx glabrous. Leaves opposite, obovate. 
Flowers pedicellate. Petals half as long as the calyx-lobes. Ovules 6 . . 2. D. Thomasii. 
1. D. fascicularis (flowers in fascicles), Rudge in Trans. Linn. Soc. xi. 299, 
t. 22 ; Benth. FI. Austr. iii. 13. An erect much-branched heath-like shrub. 
Leaves scattered, often crowded, linear, slender, semiterete or obtusely triquetrous, 
subulate-pointed, mostly 4 to 5 lines long, shortly petiolate, the floral ones not 
different or slightly longer. Flowers about 6 to 12 together in terminal heads 
within the last leaves. Bracteoles narrow and short. Calyx slender, not 3 lines 
long, the adnate part prominently 5-ribbed, otherwise smooth ; lobes very small 
and scale-like. Petals broad, about ^ line long. Staminodia short and filiform. 
Style long and slender. — Schau. Myrt. Xeroc. 36, t. 2 D.
