118 FLORA OF TASMANIA. {Onagraria. 
often large, broad, glabrous foliage, and very small flowers on pubescent ovaries ; specimens with larger flowers 
and smaller leaves appear to pass into E. Billardierianum ; and others, with narrower bases of the leaves, into 
E. glabellum. 
5. Epilobium glabellum (Forst. ex Spreng. Syst. ii. 233) ; caule simplici v. ramoso erecto v. basi 
decumbente ramis erectis, foliis oppositis breve petiolatis ovatis v. oblongo-ovatis lineari-oblongisve obtusis 
remote sinuato-dentatis, floribus paucis, capsulis puberulis glabratisve, floribus parvis. — Fl. N. Zeal. i. 60.

Hab. Port Arthur, Backhouse; Emu River, Hampshire Hills; sides of Mount Olympus, Gunn;

Disteib. New Zealand. 
The petioled, opposite leaves are the best character whereby to distinguish this species from the other Tasma- 
nian ones ; it is a common New Zealand plant, but I have only seen two characteristic Tasmanian specimens ; small 
states of this pass into E. alpinum of the European mountains, and others closely resemble E. alsinoides, also a 
European mountain plant. 
6. Epilobium junceum (Forst. ex Spreng. Syst. ii. 233) j totum pubescens tomentosum v. villo- 
sum, caulibus erectis decumbentibusve strictis v. flexuosis, foliis lmeari-oblongis obtusis remote grosse 
dentatis marginibus saepe recurvis, pedunculis plurimis e axillis superioribus subracemosis, capsulis elonga-

Distkib. South-eastern and South-western Australia, New Zealand, and extratropical western South 
America. 
The alternate narrow oblong or linear-oblong, remotely toothed leaves, are the best character for this species, 
which varies even more than its Tasmanian congeners in habit, pubescence, stature, etc. The two best-marked 
forms,— one erect, stout, strict, nearly simple ; the other decumbent, flexuose, slender, much branched,— are certainly 
far more dissimilar than any two of the last three species of the genus ; but they are inseparably connected by a 
host of intermediate grades, both in Tasmania and in New Zealand,, where it is one of the commonest plants. 
Gen. II. OENOTHERA, L. 
Calycis tubus supra ovarium productus, limbi decidui lobis 4 saspe varie connatis. Petala 4, annulo 
inserta, brevissime unguiculata. Stamina 8. Ovarium 4-loeulare, ovulis angulo centrali affixis. Capsula 
loculicide 4-valvis. Semina plurima; testa crassa, non carnosa. 
A very extensive genus, exclusively American, with the exception of the Tasmanian species ; very common 
in gardens, whence several species have escaped, and become naturalized in various countries. The genus is very 
nearly allied to Epilobium, from which it is distinguished by the tube of the calyx being elongated beyond the 
ovary, its often adherent lobes, and the naked seeds. (Name said to be from olvos, wine, and fypaa,, to chase; 
referring to a plant, the roots of which were eaten as incentives to wine-drinking; or perhaps to dispel, or chase, 
the effects of wine.)
