Scaevola. | GOODENIACEAE. 895 
equal, at length digitately spreading. Stamens 5; anthers free. Ovary 
inferior or the summit free, 2-celled; ovules solitary in each cell, erect. 
Style undivided; stigma truncate or 2-lobed, enclosed in the cup-shaped 
indusium. Fruit indehiscent, exocarp succulent or thin and membranous, 
endocarp woody or bony or rarely crustaceous. Seeds solitary in each 
cell. 
A large genus of 60 or 70 species, over 50 of which are confined to Australia. The 
remainder are scattered through the Pacific islands and along the coasts of tropical 
Asia, one extending to tropical Africa and the West Indies. The single species found 
in New Zealand is endemic. 
1. S. gracilis Hook. f. in Journ. Linn. Soc. i (1857) 129. — A procumbent 
undershrub 2-4 ft. high; branches long, spreading, and with the leaves 
clothed with silky hairs; axils of the leaves densely villous. Leaves 
alternate, 1-3 in. long, obovate-lanceolate or oblong-lanceolate, acute, 
serrate-dentate, narrowed into a rather long petiole. Flowers #in. long, 
axillary, solitary, sessile or shortly peduncled, white with a yellow eye, 
sweet-scented; bracts 2, rarely 4, linear-lanceolate. Calyx cupular, 
indistinctly lobed. Corolla with a short villous tube and 5 narrow segments, 
mucronate at the tips. Stamens equal, shorter than the corolla-tube. 
Style pilose; indusium deeply cup-shaped, margins fringed. Drupe 
globose, 2 in. long, white-—Handb. N.Z. Fl. (1864) 173.

T. F.C., W. BR. B. Oliver ! July—December. 
Hooker describes the calyx as having 3 subulate lobes and 2 shorter intermediate 
ones, but in my own specimens and Mr. Shakespear’s it is invariably cupular and very 
indistinctly lobed. 
Family CIIl. STYLIDIACEAE. 
Herbs, rarely undershrubs. Leaves alternate, scattered or densely 
imbricate, entire; stipules wanting. Flowers hermaphrodite or unisexual, — 
regular or almost irregular. Calyx adnate to the ovary; lobes 3~7, but 
usually 5, free or connate into 2 lips. Corolla polypetalous or far more 
commonly gamopetalous, 5-10-merous, but generally 5-merous; the lobes 
subregular and equal in the New Zealand genera, but in the bulk of the 
family the lowest lobe is smaller and narrower and recurved, and is known 
as the labellum. Stamens 2-3, free; but more commonly 2, with the 
filaments united with the style into a column; anthers sessile at the top 
of the column. Ovary inferior, more or less completely 2—3-celled, usually 
crowned with 1 or 2 fleshy glands. Styles rarely 2-3, or usually connate 
with the column, the stigma hidden between the column; ovules numerous 
in each cell. Fruit a 1-3-celled capsule, dehiscent or indehiscent. Seeds 
numerous or free by abortion, minute; albumen fleshy; embryo minute, 
next the hilum. 
A small family, comprising 6 genera and about 120 species, most of them falling 
into the typical genus Stylidium, which is not represented in New Zealand. Of the 
4 New Zealand genera, Donatta extends to Antarctic America; Phyllachne has a 
similar distribution; Forstera has a single species in Tasmania in addition to the 3 
found in New Zealand; while Oreostylidium is endemic. The 2 remaining genera, 
Levenhookia and Stylidium, with the exception of very few species, are confined to 
Australia and Tasmania.
