Ovary and adnate part of the calyx about 6 to 8 lines long, the free part of the 
calyx-tube at least lin. long. Petals broad and spreading. Stigma divided into 
4 linear lobes. Capsules f to lin. long, scarcely angular. 
A plant of N. American origin, long cultivated in gardens in Europe and other countries, and 
readily establishing itself in waste places on river banks, &c. Naturalised in southern 
Queensland. 
2. (E. elata (tall), H.B.K. Nov. Gen. et Sp. vi. p. 90 f CE. salicifolia, Desf.) 
A tall herbaceous perennial 4 or 5ft. high, leaves mostly tufted at the base, 
linear-lanceolate and distantly toothed and with the stem clothed by a canescent 
pubescence. Petals yellow, roundish, obovate, retuse ; stamens declinate, about 
as long as the petals. Capsule sessile, cylindrical, slightly angular, clothed by a 
silky villi. 
Hab.: A plant of Mexico and Central America now naturalised or a stray from cultivation in 
Queensland. 
3. (E. longiflora (long-flowered), Jacq. Evening Primrose. Plant with 
erect stem, pilose. Leaves oblong to lanceolate, denticulate. Flowers large, bud 
erect ; free part of the calyx-tube 3 to 4 times as long as the ovary, filiform ; 
petals yellow, nocturnal, bilobed. Stigma 4-parted ; divisions elongated. 
Stamens included. Capsule linear. Seeds minute, scrobiculate. 
Hab.: A plant belonging to Buenos Ayres, which has become naturalised at the Warrego 
River, from whence my first specimens were received in 1387 from Mr. A. P. Jones. It is also 
found about Toowoomba. 
2. EPILOBIUM, Linn. 
(Limb of calyx surmounting the ovary.) 
Calyx-tube not at all or scarcely produced above the ovary ; lobes 4, deciduous. 
Petals 4. Stamens 8 ; anthers linear or oblong. Ovary inferior, 4-celled, with 
numerous ovules in each cell ; style filiform ; stigma entire and club-shaped in 
the Australian species, 4-lobed in some others. Capsule elongated, opening 
loculicidally in 4 valves from the summit downwards. Seeds small, with a tuft 
of long hairs at the end. — -Herbs, mostly erect, or with a decumbent or creeping 
base. Leaves opposite or irregularly scattered. Flowers pink or red, rarely 
white, solitary in the upper axils or forming a terminal raceme. 
The genus is diffused over nearly the whole globe — from the extreme Arctic regions of both 
hemispheres to the tropics. The numerous forms the species assume in every variety of climate 
make it exceedingly difficult to define them upon any certain principle, and botanists seldom 
agree as to the number they should admit. The general tendency of late has been to an inordi- 
nate multiplication of supposed species. F. v. Mueller, on the other hand (Veget. Chath. Isl. 15). 
proposes to reduce the whole of the New Zealand and Australian species to the Linnasan E. 
tetragonuin, a course which will hardly be concurred in by the majority of botanists. —Benth. 
Stems erect, or decumbent at the base only. 
Flowers small. Calyx-lobes under 3 lines long and petals not twice 
as long. Stems terete. Pubescent or hoary. Leaves mostly alter-

iii. 304. Stems from a hard decumbent base, erect, terete, hoary-tomentose or 
softly pubescent, usually 1 to 2ft. high and rigid, but smaller and slender when 
starved. Lowest leaves opposite, the upper ones and often nearly all alternate, 
sessile, linear-oblong, remotely sinuate-toothed, the larger ones often 2in. long or 
more, but mostly smaller and the upper floral ones often very much reduced, all 
hoary or pubescent. Flowers in the upper axils sometimes quite small, but the 
calyx-lobes usually 2 to nearly 3 lines long, the petals rather longer, the pedicels
