614 THYMELHACER. [Pimelea, 
11. P. Lyallii, Hook. f. Fl. Nov. Zel. i. 222—A small stout 
prostrate or suberect much-branched shrub 6-18 in. high; branches 
sometimes long, spreading or trailing, at other times shorter, 
ascending or erect ; the younger ones more or less silky-pilose with 
appressed hairs, rarely almost glabrous; bark dark red-brown. 
Leaves usually close-set, erect or patent, +4 in. long, linear-oblong 
or elliptic-oblong or lanceolate, acute or acuminate, concave, nerve- 
less, glabrous above or nearly so, silky with long hairs beneath or 
almost glabrate; floral leaves similar to the others. Flowers in 
4-12-flowered heads at the tips of the branches, white. Perianth 
about +in. long, densely silky-villous; lobes ovate-oblong, obtuse. 
Anthers short, oblong.—Handb. N.Z. Fl, 245. 
Var. sericea.— Usually erect. Branchlets and leaves on both surfaces 
densely clothed with long silky appressed hairs, the leaves usually larger and 
broader.

StEewaRrr IstaAnD: The typical form abundant in mountain districts throughout. 
Var. sericea: Kurow and other places in the Waitaki Valley, Buchanan ! 
Petrie! Clutha Valley, Petrie! Crown Range, Cardrona, Kirk ! Usually 
from 2000 to 4500ft., but descends to sea-level in the south of Otago and on 
Stewart Island. December-—March, 
An exceedingly variable plant. Slender erect forms approach P. virgata, 
others with smaller almost glabrous leaves seem to pass into P. levigata, while 
the extreme state of var. sericea has much of the appearance of P. arenaria. 
Var. sericea is referred to P. virgata in Kirk’s herbarium, but I think it is 
better placed under P. Lyallii. 
12. P. sericeo-villosa, Hook. 7. Handb. N.Z. Fl. 245.—A much- 
branched prostrate shrub, forming compact depressed patches 
3-18in. across, everywhere densely villous with long pale silky 
hairs ; branchlets short, stout, densely leafly. Leaves crowded, 
closely imbricating, erect, -+in. long, linear-oblong or elliptic- 
oblong, obtuse or acute, concave, both surfaces villous with long 
straight hairs, which usually completely conceal the leaf. Flowers 
in 2-6-flowered heads at the tips of the branches, white. Perianth 
4-t in. long, densely silky-villous ; lobes ovate-oblong, obtuse.

son — Wairau Mountains, Travers; Jollie’s Pass, Haast! T. F.C.; Upper 
Clarence Valley, T. F.C. Canterbury—Lake Tekapo and Mackenzie Plains, 
T. F. C. Otago—Waitaki Valley, Hector and Buchanan! Clutha Valley, from 
Cromwell to Lake Wanaka and Lake Hawea, Petrie ! 500-3500 ft. De- 
cember-March. 
Differs from P. Lyallii in its more completely prostrate and often densely 
compacted habit, and in the far more copious covering of long straight silky 
hairs.
