Phyllachne. | STYLIDIBA. 391 
Var. Haastii,— Upper half of leaf narrower, semiterete, not thickened at the 
tip.—P. Haastii, Berggr. in Journ. Bot. ix. n.s. (1880) 104. P. Colensoi, Berggr. 
in Minnesk. Fisiog. Salisk. Lund. (1877) t. 3, £. 1 to 27. 
Noxrs anp SoutH Isnanps, Stewart IstanD: From Hikurangi, Tongariro, 
and Mount Egmont southwards, an abundant alpine plant. 3000-6000 ft. 
December-February. 
This appears to pass imperceptibly into P. clavigera, and should be regarded 
as a variety of that species. 
3. P. rubra, Cheesem.—Stems shorter than in P. clavigera, 
4-lin. high, densely tufted, frequently bare of leaves below. Leaves 
erect, very densely imbricated, linear, not dilated at the base or very 
obscurely so, very thick and coriaceous ; tips much thickened, form- 
ing a large globose knob. Flowers 4-1 in. diam., white, but becom- 
ing dark-red when dry. Corolla-lobes 5-7, unequal. Column 
stout, included or slightly exserted. —Helophyllum rubrum, Hook. 
jf. Handb. N.Z. Fl. 168; Buch. in Trans. N.Z. Inst. xiv. (1882) 351, 
t. 31, f. 2. 
SoutH Istanp: Otago—Mount Aspiring Range, Buchanan and McKay ! 
Mount Arnould and the Hector Mountains, Petrie ! 4500-6000 ft. January— 
March. 
This is evidently close to P. clavigera, but the large globose knobs at the 
tips of the leaves give it a distinct appearance. 
2. OREOSTYLIDIUM, Berger. 
A small stemless perennial herb. Leaves numerous, all radi- 
eal. Scape short, 1- flowered. Calyx more or less evidently 
2-lipped ; lower lip 2-fid, upper lip 3-fid. Corolla almost regular, 
campanulate, deeply 5-lobed; the lobes equal in size, irregularly 
spreading. Column short, straight, erect, much shorter than the 
corolla-lobes; anthers didymous, 4-celled and 4-lobed ; lobes ulti- 
mately spreading; stigma placed between the anthers, 2-lobed, 
lobes spreading and deflexed. Ovary 2-celled or 1-celled by im- 
perfection 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 nu- 
merous, Obovoid; testa lax, cellular. 
A monotypic genus confined to New Zealand. It differs from Stylidiwm 
in the corolla-iobes being equal in size, in the short erect column, and in the 
indehiscent fruit. 
1. O. subulatum, Berggr. in Minnesk. Fisiog. Sallsk. Lund. 
Gacinan vii. 1, t. 1.—Small, densely tufted. Rootstock short, 
often emitting stolons ; roots long, fibrous. Leaves spreading and 
recurved, 4-14 in. long, linear-subulate, mucronate or almost 
pungent, rigid when dry, concave above, slightly convex beneath, 
quite glabrous; margins entire. Scape much shorter than the
