ANDROSACE L. 



A. Chaixii G. G. = A. lactiflora Pall. Leaves oblong - lanceolate, 

 slightly toothed, in a rosette. Calyx glabrous, larger at maturity, shorter than

 Central flower-stalk erect, the others spreading. Plant 4-8 in. high. Biennial 

 or annual. 



Mountain woods and pastures, uncommon. April-June. 



A. maxima L. An annual species 2-4 in. high. Leaves in a radical rosette, 

 obovate wedge-shaped, toothed at the top. Scape short, bearing a loose umbel of 

 white or pir.kish flowers. Calyx large, downy and becoming larger at maturity, 

 lobes ovate-lanceolate, longer than the tube. Corolla and capsule shorter than 

 the calyx. 



Fields and crops in the hill district, especially on limestone, as e.g. the Sainte- 

 Baume region. April-June. Uncommon. 



PRIMULA L. 



P. vulgaris Huds. = P. grandiflora Lamk. Primrose. The common 

 primrose is found in several places in the north of the Var. In Liguria and les 

 Alpes-Marit. it is quite common on banks, damp woods, and shady hill-sides 

 in the chestnut zone up to about 1200 m. and descending the valleys to near the 

 sea. February- May. 



P. suaveolens Bert. This is the variety of the Cowslip (P. veris L.) 



found on grassy banks and damp woods from about 600 to 1700 m. and occasion- 

 ally descending near the coast (C. Bicknell). The leaves are generally more 

 cordate and less rugose than in the type, and the under surface is whiter 

 and tomentose and the petioles less winged. The flowers are often larger and 

 the calyx more inflated. March-May. The true Cowslip does not appear. 



P. marginata Curt. (Plate XX). Stem 2-6 in. high, fleshy, bearing a few- 

 flowered umbel of rather large rose-purple flowers. Leaves smooth, thick, ovate- 

 elliptical and narrowed into a petiole, and with a cartilaginous, serrate, mealy- 

 white margin. Petals obcordate. Capsule subglobular. A rather variable plant 

 according to position, etc. 



Rocky, limestone places in the mountains, descending to about 800 m. near 

 San Dalmazzo di Tenda and Buggio in Liguria, to the mountains above 

 Menton, and the west of the montagne de Brouis in the Var. 



P. Allionii Lois. A small species 2 in. high, pubescent and viscous. Scape 

 much shorter than the leaves, and bearing a solitary bright rose flower. Leaves 

 obovate, petioled, entire or crenate, velvety and very viscous. 



Rocks in the sub-Alpine region of the Maritime Alps (endemic) and descend- 

 ing to the gorge of Saorge below San Dalmazzo di Tenda. March- May.
