22 FLORA OF TASMANIA. [Crucifera. 
edentula. Silicula bivalvis, lineari-oblonga v. elliptica, septo parallele compressa, valvis concavis. Semina 
biseriata, pendula, iinmarginata, fuiiiculis brevibus; cotyledonibus incumbentibus. — Herbse, foliis linearibus ; 
floribus raeemi catihusve. 
Slender, erect or decumbent plants, with a few linear leaves and elongated racemes of erect or nodding flowers. 
Sepals narrow, erect. Petals with a narrow limb, often twisted. Pod oblong ; valves convex. Seeds in two rows, 
with short funiculi and incumbent radicle. — This genus, of which about six species are known, is quite confined to 
Australia, and varies greatly in habit, as also in the length of the petals, from which the generic name was derived. 
The species chiefly occur in the southern and western parts of that continent, one extending into Tasmania. (Name 
from arrevos, narrow, and neraXov, a petal.) 
1. Stenopetalum liueare (Br. in DC. Syst. ii. 513) ; caule simplici v. ramoso erecto v. basi decum- 
bente, foliis integris anguste linearibus, racemis elongatis strictis apice puberulis, floribus breviter pedicellatis 
erectis, sepalis anguste linearibus, siliquis anguste lineari-oblongis erectis pedicello duplo longioribus, valvis 
concavis, costa distincta.— Hook. Ic. PI. t. 618. S. gratulatorum, Ferd. Miitter ? {Gunn, 1941.) 
Hab. South Esk River, thirty miles from Launceston, Gunn. 
Distrib. South-eastern and South-western Australia. 
This appears to be Brown's 8. lineare and Mailer's 8. gratulatorum of Port Adelaide in Herb. Bentham, and 
perhaps of Port Phillip, though the specimen of the latter in Herb. Hook, is a very much branched, robust plant, with 
pubescent branches. Neither ' uncus (in Herb. Bentham), nor the Tasmanian ones, are as slender 
as that described by Brown. The leaves are both entire and somewhat pinnatifidly cut in the Port Phillip speci- 
men, and the repliim seems rather stronger than in the Tasmanian ones. As I have only one good example of Gunn's 
plant, some allowance must be made for this description, all these Crucifera being excessively variable, especially 
in habit, robustness, foliage, and often in comparative length of pod.— Branched from the base, a foot high; stems 
slender, rigid, with a few narrow linear, entire leaves 1 inch long. Racemes (fruiting) 6 inches long. Flowers erect, 
I inch long, on short erect pedicels (yellow ? or purplish ?). Pods T 3 „ inch long, ft inch broad, erect, on stout erect 
pedicels half their own length. Valves concave, with a stout dorsal nerve ; septum membranous. Seeds about 15- 
20, from the narrowness of the pod almost uniseriate, pale yellow-brown.— There is (in Herb. Hook.) an imper- 
, apparently of this species, from the interior of the Port Jackson Colony (A. Cunningham), with pinna-

Sepala sequalia. Petala integra. Stamina edentula. Silicula latere compressa, oblonga v. subrotunda ; 
valvis concavis, subcarinatis. Semina pauca v. plurima ; cotyledonibus incumbentibus v. accumbentibus. 
Generally small slender weeds, natives of Europe and subalpine regions, with pinnatifid radical leaves, erect or 
decumbent, simple or branched stems, and small flowers in terminal racemes.— Sepals 4, equal, spreading. Petals 
4, entire. Pod short, laterally compressed, oblong or rounded ; style very short ; valves concave ; seeds few or many, 
with free funiculi and incumbent or accumbent cotyledons. (Named in honour of Miss HutcHns, an eminent Irish 
botanist.)
