24 FLORA OF TASMANIA. [Crucifera. 
Hab. Arthur's Lake, elev. 3000 feet, amongst moss, Gunn.— (Fl. Oct.) 
A very distinct little plant, whose genus must remain doubtful till ripe fruit is examined. Annual, erect, 3-6 
inches high, stiff, glabrous or hirsute with lax hairs.— Stow sometimes branched, stiff and flexuose. Radical 
leaves \-\ inch long, lanceolate, spathulate, petiolate ; cauline linear-oblong, with sagittate bases. Mowers white, 
T V inch broad. Sepals glabrous or hairy. Pedicels of unripe fruit spreading, stiff, i inch long. Seeds about 8. 
Gen. YII. DBABA, L. 
Sepala ereeta. Petala 4, limbo explanato. Stamina edentula. Silicula subelliptica v. elliptico- 
oblonga, compressa; valvis convexis planiusculisve, 1-nerviis. Semina plurima, 2-seriata, funiculis capil- 
laribus liberis. Cotyledones accumbentes. — Herbse, Mis integerrimis ; floribus flavis v. albis. 
A large European genus, most abundant on the Alps and mountains of Scandinavia, Greece, and Asia Minor, 
also extending into the northern regions of America. Very many species are natives of the Andes, and a few arc 
found in Fuegia, but none in New Zealand, or elsewhere in the southern regions of the Old "World, except 
the D. nemoralis of Tasmania. Most of the species are tufted alpine herbs, but not the present, which is a lax- 
growing plant, — Leaves entire or toothed; radical petiolate; cauline sessile or amplexicaul. Flotcers white or 
yellow, corymbose or racemose. Sepals four, suberect. Petals with an expanded Hmb, not bilobed. Pod short, 
blong or obovate, rarely linear ; valves flat, or slightly convex ; septum entire, membranous. Seeds nu- 
merous, with slender funiculi. Cotyledons accumbent. (Name from bpafir), acrid.) 
1. Draba nemoralis (Linn. Sp. PI. i. p. 643); pnbescens, caulibus gracilibus parce ramosis, foliis 
radicalibus oblongis spatlmlatisve integerrimis dentatisve caulinis sessilibus latioribus dentatis, floribus albis, 
sepalis pilosis, siliculis suberectis obovatis v. elliptico-oblongis pedicello gracili divergente, valvis planiusculis 
membranaceis puberulis, septo enervi, seminibus late ovato-oblongis. — DC. Prodr. i. 171; Engl. Bot. 
t. 912. {Gunn, 1025.) 
Hab. Dry places near Hobarton, and on the banks of theDerwent at the Cataracts, Backhouse, Gunn. 
-(FLOct.) (*.*.) 
Distrib. Middle and Southern Europe, Asia Minor, Soongaria; also found in Sweden, and the 
Northern United States. 
This is undoubtedly the European D. nemoralis, and apparently perfectly wild in Tasmania. The specimens 
are small and simple, with shorter pods than in many northern forms, but quite similar to others. Annual, pubes- 
cent or pilose, 1-6 inches high, simple or branched. — Radical leaves oblong or spathulate, entire or toothed, |-1 
inch long; cauline sessile, broader-toothed. Flowers minute, white. Sepals oblong, pilose. Petals spathulate. 
Stamens nearly equal. Ovary broadly oblong, pubescent, with a short stout style. Pods on slender spreading 
pedicels, \ inch long, erect, obovate or elliptical-oblong ; valves flat, membranous, pubescent, with a slightly-raised 
mesial line. Seeds about twelve in each valve, on long slender funicles, broadly obovate-oblong. Septum nerveless. 
Gen. VIII. LEPIDIUM, L. 
Sepala suberecta v. patentia. Petala 4, integra, v. 0. Stamina 6 v. pauciora. Silicula latere com- 
pressa, ovalis, apice integra v. biloba, valvis carinato-apteris alatisve, septo angusto. Semina loculis soli- 
taria, e apice septi pendula, rarius gemina. Cotyledones incumbentes.— Herbse, foliis variis ; racemis demum 
elongatis ; floribus parvis, albis, interdum imperfectis. 
A large genus, chiefly of natives of the north temperate zone, with some southern ones, most of which are 
maritime plants.— H erbs, with often suffruticose stems. Leaves entire, toothed, mr sinuate, rarely pinnatifid. Flowers 
white, small, racemose, often imperfect ; racemes elongated in fruiting. Sepals spreading or suberect. Petals four,
