Flora of New Zealand Series

Type locality: "Damp woods of Wangaroa". Type: K, R. Cunningham, 1834.

Slender, straggling to sublianoid; stems up to 3 dm. or more long, slightly scabrid on angles or nearly glab., hairs retrorse; branches and branchlets similar, very slender. Lvs and stipules similar, forming rather distant whorls of 4, on flat retrorsely hairly petioles c. 1 mm. long. Lamina patent, linear- to narrowly oblong-lanceolate to narrow-oblanceolate (all forms may be on single plant), 6-10-15-(20) × 2-4 mm.; acuminate, sts awned, sts apiculate, gradually narrowed to base; margins, and midrib below, scabridulous. Fls c. 2 mm. diam., in (1)-3-4-fld axillary cymes. Peduncles slender, c. 15 mm. long, decurved in fr.; pedicels filiform, c. 4 mm. long. Calyx minute; corolla white, tube minute. Fr. of 2 globose cocci 1-1·5 mm. diam., very dark brown, with sparse appressed hairs to glab

DIST.: N., S., St., Ruapuke Id. Lowland to montane in damp places in forest, edges of swamps, bogs, grassland from c. lat. 35º southwards.

A rather polymorphic sp., especially as to the development of the indumentum. Colenso (T.N.Z.I. 20, 1888, 192) based his G. triloba on specimens from "Edges of streamlets in dense shaded woods near Danneverke . . . 1887; W. C." The corolla is described as "cream-coloured, trilobed; lobes broadly-ovate or deltoid-rotund; tips sub-acute, their upper margins slightly fringed tubercular". The type, in W, and material at K, is a slender form of G. tenuicaule, in poor condition.
