XL. STYLTDIEjE.

brown. Scape very slender, strict, 2-4 in., 1- rarely 2-flowered. Flower 
very variable; bracts linear-oblong. Calyx-lobes linear, obtuse. Corolla 
in. diam. ; tube very short ; lobes linear-oblong. Stamens included. 
Middle and Southern Islands: Dusky Bay, Forster ; Chalky Bay, Lyali ; Rangitata 
range, alt. 2500-5000 ft. Sinclair ; Mount Dobson, 6500 ft., Haast ; grassy banks, Otago 
alps, alt. 4-6000 ft., Hector and Buchanan. 
2. F. Bidwillii, Hook. f. FI. N. Z. i. 155. Stems 2-8 in., more 
slender than in F. sedifolia. Leaves numerous, close-set, but not imbricate, 
patent and recurved, in. long, linear or linear-oblong, coriaceous, not 
shining, green ; margins recurved when dry ; midrib beneath very indistinct. 
Mowers smaller than in F. sedifolia. 
Northern Island: Tongariro, Bidwill ; summit of the Ruahine range in sbaly plaees, 
Colenso. 
8. F. tenella, HooTc.f. FI. N. Z. i. 154. Stem short, 1-2 in. Leaves 
few, lax, erect or patent, not recurved, in. long, narrow, oblong-obovate, 
contracted into a short petiole, subacute, margins recurved, midrib obsolete, 
not shining nor thickly coriaceous. Scape and flower as in F. sedifolia. 
Middle Island : Otago, on a bill 1800 ft. high, aud at Milford Sound, Lyali ; Southern 
Alps, Haast. Intermediate in some respects between F. Bidwillii and F . sedifolia, but 
has shorter stems and less coriaceous foliage than either ; the leaves are as short as in sedi- 
folia, but neither imbricate, recurved, coriaceous, shining, nor furnished with a thick cunei- 
form midrib. At the same time I can hardly doubt these three forms having been very 
recent offshoots from one. 
2. HELOPHYLLUM, Hook. f. 
Densely tufted, moss-like plants. Leaves most closely imbricating, ter- 
minated by a globose knob. Mowers solitary, sessile in the uppermost leaves, 
2- or 3-bracteate, white or pink, polygamo-dicecious.— Calyx-tube obconic ; 
lobes 5-7, obtuse. Corolla-tube short ; limb spreading, unequally 4-9-par- 
tite, often with thickened glands at the base of the lobes. Ovary incompletely 
2-celled. Epigynous glands 2, semilunar. Eruit small, turbinate, coriaceous, 
1-celled, dehiscent only by the falling away of the summit. Seeds numerous, 
obovoid ; testa brown, coriaceous ; albumen very fleshy ; embryo not seen, 
probably most minute. 
In the ‘ Flora Antarctica,’ I regarded the first-discovered species of this genus as a section 
(. Helojihyllum ) of Forstera. I did not then know the fruit, which being turbinate and 
indehiscent, together with the most peculiar habit of the three species now known, esta- 
blishes an excellent genus. The three species here described appear very distinct in the 
drawings sent me by Mr. Buchanan, but I suspect they may prove forms of one very variable 
plant. There is much in the habit and characters of Bonatia that approaches this genus, 
and I think that Stylidiece are more nearly allied to Saxifrage ce than to any other Order.
