900 STYLIDIACEAE. [Oreostylidium, 
and 4-lobed; lobes ultimately spreading; stigma placed between the 
anthers, 2-lobed, lobes spreading and deflexed. Ovary 2-celled or 1-celled 
by imperfection of the dissepiment; ovules numerous, attached to the 
centre of the dissepiment. Capsule coriaceous, indehiscent or tardily 
rupturing, more or less completely 2-celled. Seeds numerous, obovoid ; 
testa lax, cellular. 
A monotypic genus confined to New Zealand. It differs from Stylidium in the 
corolla-lobes being equal in size, in the short erect column, and in the indehiscent fruit.

Family CIV. COMPOSITAE. 
Herbs, shrubs, or small trees. Leaves alternate, rarely opposite or 
whorled ; stipules wanting. Inflorescence composed of one or maxy flower- 
heads (capitula), each consisting of numerous minute flowers (florets) sessile 
and densely packed on the enlarged tip of the flower-stalk (receptacle), sur- 
rounded by an involucre of whorled bracts and resembling a single flower. 
Heads either solitary and terminal (rarely axillary) or arranged in corymbose 
cymes or panicles, sometimes contracted into clusters or even compound 
heads. Involucre of few or many bracts (scales of the involucre) arranged 
in one or several rows. Receptacle either naked (no bracteoles mixed with 
the florets) or with bracteoles in the shape of chaffy scales or bristles (paleae) 
placed at the outside of most or all of the florets, sometimes with the surface 
pitted or honeycombed. Florets many or few (very rarely 1), either all of one 
kind as regards sex, when the heads are said to be homogamous, or of more 
than one kind, when they are called heterogamous. The homogamous heads 
either have all their florets tubular and hermaphrodite (dzscozd) or all ligulate 
a: d hermaphrodite (liguliflorous). The heterogamous heads frequently have 
the central florets tubular and hermaphrodite or male, and the outer ones 
ligulate and female or neuter. The heads are then said to be radiate. The 
tubular florets in the centre are called florets of the disc, or simply disc- 
florets ; the ligulate ones florets of the ray, or ray-florets. Heterogamous 
heads are also discoid when the marginal female florets have tubular corollas
