162 FLORA OF TASMANIA. [Umbettifera. 
The majority of the species of this genus are South Australian and Tasmanian ; a few only are New Zealand 
and South American. In the New Zealand Flora I have pointed out that the structure of the seed has been mis- 
understood, and that, being plane or only slightly concave in front (not, as has been described, convolute or deeply 
grooved), the genus belongs to the tribe Seselinea. I much doubt whether all the species here described are different 
from one another, but as I do not know how to divide them better, I have followed Mr. Grunn's numbers.— Herbs, 
glabrous or often very silky in all parts. Leaves all radical, decompound, finely cut. Scapes erect, simple or 
proliferously branched, bearing one simple umbel of sessile or pedicelled flowers, surrounded with a many-leaved 
involucre. Calyx-limb obsolete. Petals often hairy, with incurved tips. Styles short, recurved. Fruit elongate, 
ovate, nearly terete, somewhat laterally compressed ; mericarps semiterete, each with five blunt ribs and a single 
row of vittse in the interstices. (Name from opos, a m an umbelliferous plant.) 
1. Oreomyrrhis eriopoda (Hook, fil.) ; tota appresse cano- v. sericeo-pilosa, foliis lanceolatis bi- 
pinnatisectis, segmentis lobatis laciniatisve, scapis gracilibus superne retrorsum pilosis, involucri foliolis 
oblongo-lanceolatis, fructibus elongatis pedicellis villosis multo brevioribus sequilongisve. — Caldasia eriopoda, 
DC. Prodr. iv. 229. {Gunn, 491.) 
Hab. Common in grassy pastures, etc., in various localities, both on the mountains and plains, Gunn. 
— (El. Oct., Nov.) 
Distrib. New South Wales and South-eastern Australia. 
Whole plant 6-18 inches high, covered everywhere except on the fruit with rather silky hairs, which are 
retrorse on the upper part of the scape, but appressed elsewhere. Leaves on slender petioles, lanceolate, bipinnati- 
sect, the pinnules finely cut into narrow laciniae. Scapes proliferously branched in Victoria specimens and leafy at 
the axils. Fruit elongate-ovate, on stout, villous pedicels as long as or much longer than themselves.— Dr. 
Mueller sends a state of this plant from Victoria with very long, narrow-linear fruit, three or four times as long as 
the pedicels. 
2. Oreomyrrhis brachycarpa (Hook, fil.) j sericeo-pilosa, foliis linearibus lineari-lanceolatisve bi- 
pinnatisectis, fructibus breviter ovatis pedicellis villosis brevioribus subsequilongisve. — Caldasia brachycarpa, 
Nob, in Hook. Ic. PI. sub t. ccc. {Gunn, 882.) 
Hab. Elevated parts of the Colony, as at Middlesex Plains, St. Patrick's Eiver, and Lake St. Clair, 
Gunn.—{Yl. Dec.) 
Intermediate between O. argentea and 0. eriopoda, having the silky pubescence less shining than in the former, 
and more so than in the latter. Fruit much shorter, and leaves smaller and narrower, than in 0. eriopoda. 
i argentea (Hook, fil.); robusta, tota dense argenteo-sericea et villosa, foliis linearibus 
bipinnatisectis nitidis, involucri foliolis ovatis obtusis, fructibus sericeis ovatis pedicellis villosis brevioribus. 
—Caldasia argentea, Nod. in Hook. Ic. PI. t. ccc. {Gunn, 823.) 
Hab. Mountainous parts of the Colony, 3-4000 feet, Middlesex Plains, Lake Echo, etc., Gunn.— 
(Fl. Nov., Dec.) 
A very beautiful, short, robust, alpine species, readily distinguished from 0. brachycarpa, to which it is nearly 
allied, by the shining, villous, silky, and silvery foliage, scapes, and pedicels. 
4. Oreomyrrhis sessiliflora (Hook. fil. in Lond. Journ. Bot. vi. 471) ; laxe pilosa, foliis lanceo- 
latis linearibusve pinnatisectis, foliolis ovato-oblongis pinnatifidis pilosis glabratisve, segmentis lanceolatis 
linearibusve acuminatis integris lobatisve, scapis simplicibus v. subumbellatim proliferis, involucri foliolis 
lmeari-oblongis basi coadunatis, fructibus brevissime pedicellatis lineari-elongatis glabris sericeisve. {Gum, 
Hab. Summit of Ben Lomond and of the Western Mountains, elev. 4-5000 feet, Gunn.—fil Jan.)
