36 FLOWERING PLANTS OF THE RIVIERA 



C. silvatica Lk. = C. flexuosa Wilh. Wood Bitter-cress. Very similar 

 to the last, but with flexuose, angular stem. Leaflets broader and less deeply 

 toothed. Petals oblong, about twice length of calyx. Pods rather spreading. 



Damp, shady places. April-June. Aiguines in the Var. 



C. hirsuta L. Hairy Bitter-cress. Leaves pinnate, with 5-9 segments, 

 leaflets of lower leaves often rounded, of upper leaves narrow, almost linear, 

 usually entire. Petioles not auricled. Petals small, narrow, white. Notwith- 

 standing the name, the plant is more often glabrous than hirsute. 



Cultivated and waste ground, and damp, sandy places. Common. February- 

 May. 



DENTARIA L. TOOTH-CRESS. 



Often now placed with Cardamine, from which it seems to differ chiefly in 

 the funicle being dilated instead of filiform. 



D. bulbif era L. = Cardamine bulbifera Crantz. Coral-root. Root-stock 

 scaly, whitish. Stem 1-2 ft. high, with several leaves, often with a small bulbil 

 at their axil ; lower leaves pinnate, with 5 or 7 segments, upper ones with 

 fewer segments or entire ; segments lanceolate, entire or toothed. Flowers few, 

 large, bright lilac, rarely white. Pod seldom formed, and the plant is propagated 

 by the bulbils falling to the ground. 



Woods and shady places in the Maritime Alps. April-May. Col de Tenda, 

 Val de Pesio. 



D. digitata Lamk. = C. pentaphylla R. Br. A smaller plant with no 

 bulbils. Leaves digitate and divided into 3-5 leaflets, which are oblong-lanceo- 

 late and toothed irregularly. Flowers rose or lilac. Pod erect, spreading. 

 Root-stock scaly, fleshy. Calyx often reddish. 



Mountain woods in the Maritime Alps, fairly common. June-August. 



D. pinnata Lamk. = C. pinnata R. Br. Root-stock scaly, obtuse. Stem 

 stout, i-2 ft. Leaves pinnate, with 5-9 leaflets, which are lanceolate and ir- 

 regularly toothed. No bulbils. Flowers large, lilac, rose, or white. Petals 3 

 times longer than the green calyx. Pods and pedicels erect, spreading. 



Mountain woods, especially of beech. May-June. Very rare in the Var 

 (Aiguines, north of Marges) ; commoner in Alpes-Marit. as at Mont Mulac 

 above Menton, and valley of Cairos. Hills above Bordighera. 



SISYMBRIUM L. 



* Flowers yellow. 



S. officinale Scop. Hedge-mustard. Lower leaves runcinate, upper ones 

 hastate ; sepals erect. Pods short, very pointed, adpressed against the stem. 

 Flowers small, pale yellow, solitary in the leaf axils. Annual, hairy, 1-3 ft. high. 



Cultivated and waste places, common. May-July. 



S. polyceratium L. Lower leaves runcinate, upper ones hastate, smaller 

 than in the last. Pods short, pointed, inflated. Flowers small, pale yellow, 2 or 

 3 in the axils of the leaves. An annual or biennial, almost glabrous, about a foot 

 high, very leafy. 



Old walls, ruins, and rubbish heaps in the Var. May-July. Excluded by 

 Burnat from les Alpes-Marit. 



S. Columns; Jacq. A biennial, rather hoary plant, 1-2 ft. high. Lower 

 leaves petioled, runcinate-pinnatifid, the upper lobe hastate ; upper leaves linear 

 entire, peduncles equalling the erect sepals. Pods very long, not inflated. 



Borders of roads and waste places. May-June. 



S. austriacum Jacq., with runcinate pinnatifid leaves, grows in the moun- 

 tain region, usually above 1000 m. 



S. Sophia L. Flixweed. Leaves 2-3 pinnatifid, segments narrowly linear, 

 spreading. Flowers very small, ^ in. in diameter, pale yellow. Pods slender, 

 terete, ascending, curved ; pedicels very slender. Stem 1-3 ft. branched above. 



Waste places near houses, etc. May-July. Annual.
