CRUCIFER^E 31 



Arable fields. April-June. Rare on the Riviera, as at Toulon and Chateau- 

 double. 



F. officitialis L. Common Fumitory. Diffuse. Leaf segments narrowly 

 oblong, flat. Sepals ovate-lanceolate, one-third length of corolla. Corolla 

 rather small, reddish or rose, with purplish tip, lower petal abruptly dilated at 

 apex. Fruit usually broader than long, depressed, rugose when dry. 



Cultivated fields, gardens, and waste places, common. March-July. 



F. Vaillantii Lois. An erect, slender, glaucous much-branched species. 

 Leaf segments distant, narrow, almost linear, flat. Flowers very small, pink, 

 with purplish tip ; lower petal abruptly dilated at apex. Sepals minute. Fruit 

 small, nearly globose, rounded-obtuse above, rugose when dry. Bracts shorter 

 than the pedicels (they are about as long in parviflora). 



Arable fields, rare in the Var, as at Sollies-Toucas and La Farlede. Occa- 

 sional in the mountain region behind Bordighera and San Remo. April-June. 



The var. Chavini R. et Fouc. (p. Chavini Reut.), more robust, with 

 more compound leaves and longer racemes of brighter flowers, has also been 

 found. 



F. parviflora Lamk. Diffuse. Leaf segments very narrow, linear, 

 channelled, glaucous. Sepals minute. Corolla very small, broadly winged, 

 white or pale rose, partially tipped with dark purple ; lower petal apically 

 abruptly dilated. Fruit small, subacute or apiculate, rugose when dry. 



Sandy places and cultivated fields, common. March-May. 



Those who require a detailed description of the plants of this perplexing 

 genus should consult Mr. Pugsley's careful work on "The Genus Fumaria in 

 Britain," originally published as a supplement to the "Journal of Botany," 1912. 

 We understand he is now engaged in revising the whole genus. 



PLATYCAPNOS Bernh. 



P. spicatus Bernh. = Fumaria spicata L. (Plate V). A very distinct 

 Fumitory ; erect, often with many stems springing from the root. Leaf seg- 

 ments short, linear, glaucous. Flowers very small, bright pink except the green 

 apex, in short oval, dense heads. Sepals lanceolate-acute, one-third length of 

 corolla. Fruit oval, flattened, with thick rim. 



Arable fields, local. March-June. Ardoino's record from Nice is excluded by 

 Burnat. Locally common in the Var about Toulon, Carqueiranne, La Garde, 

 La Farlede, Hyeres, Frejus, etc. 



A variety with white and green corolla (var. alhoviridis Reyn.) is found 

 between La Seyne and Sanary. 



CORYDALIS DC. 



C. solida Swartz = C. bulbosa DC. Bulb solid. Stem simple, bearing 

 2-4 leafy bracts. Leaves twice tripinnate ; segments wedge-shaped. Bracts 

 herbaceous, digitate, rarely entire. Flowers purple, sometimes white, in terminal 

 erect heads which are elongated after flowering. Spur elongated. Pedicels as 

 long as the capsule. 



Shady places in the lower mountains. April, May. La Sainte Baume, 

 Foret de Marges, Ampus, and probably in most of the woods in the north of the 

 Var. Mountains above Menton, Grasse, etc. 



CRUCIFER^;. 

 A. Pods elongate (except sometimes in Nasturtium), dehiscing throughout 



their length, flat or turgid.

 white, yellow, or lilac. 



* Stigmas erect or decurrent on the style MATTHIOLA. 



** Stigmas small, simple, terminal. 



Lateral sepals saccate. Hairs forked CHEIRANTHUS. 



Pods terete, valves turgid. Seeds minute, 2 seriate NASTURTIUM
