160 FLOWERING PLANTS OF THE RIVIERA 



C. alba Presl. and C. Trifolii Bab. are also found. The latter is sometimes 

 in great quantity in Clover and Lucerne fields. Very probably other species of 

 Cuscuta may occur on the French Riviera and especially in the hill districts, 

 but the flowers are so minute that the different species are not easily dis- 

 tinguished.

Tribe I. CERINTHE^E. Carpels 2, a-celled, fixed on the receptacle. Corolla 

 tubular, throat naked CERINTHE. 



Tribe II. ANCHUSE^E. Corolla regular; throat closed with scales. Nutlets 

 inserted by broad cup-shaped bases on the flat receptacle. Carpels 4. 



Corolla rotate. Anthers exserted, conniving in a cone BORAGO. 



Corolla salver-shaped. Anthers included ANCHUSA. 



Corolla with slightly bent tube, and rather oblique spreading limb LYCOPSIS. 



Corolla tubular, with 5 narrow scales at throat. Anthers included. SYMPHYTUM. 



Tribe III. LITHOSPERME^E. Corolla usually regular ; throat naked or closed

HELIOTROPIUM. 



CERINTHE L. 



C.asperaRoth.(C. major Law.) (Plate XXII). Leaves oval, auricled, very 

 rough, ciliated, often spotted. Corolla naked at the throat, with 5 short teeth 

 which are acuminate and reflexed. Anthers as long as the filaments. Flowers 

 rather large, yellow, with a dark crimson ring at base. Upper bracts often 

 beautifully coloured. 



Borders of fields and stony places. March- May. 



C. minor L. Leaves oblong, auricled, not ciliate. Corolla lobes linear, 

 very acute, connivent. Anthers 4 times as long as the filaments. Flowers 

 smaller, yellow, with a scarlet band at base. 



Woods and thickets in the lower mountains. May-July. 



BORAGO L. 



B. officinal is L. Common Borage. A stout, rough, and yet elegant plant a 

 foot or more high. Lower leaves obovate or oblong, narrowed into long stalks ; 

 upper ones narrower and more shortly stalked. Flowers on long pedicels, droop- 

 ing, of a very bright clear blue (perhaps the bluest colour of any flower) ; 

 anthers dark and very prominent.

 on 3 February, near Hyeres.
