io8 FLOWERING PLANTS OF THE RIVIERA 



Old walls, rocks, and banks, common. May-July. Also frequent on the 

 Palms at Hyeres, etc. 



S. altissimum Pair. Plant 1-2 ft. high, with erect leafy stems, glabrous 

 and glaucous, and with densely imbricate leaves on the barren shoots. Leaves 

 ovoid-lanceolate mucronate, thick. Flowers subsessile, very' pale yellow in a dense 

 corymb. 



Borders of fields, rocks, and stony hills, common. June-July. 



S. anopetalum DC. = S. ochroleucum Chaix. A foot high, glaucous, 

 glabrous, with barren shoots covered with densely imbricate leaves. Leaves 

 cylindric, mucronate, shortly spathulate at base. Flowers very pale yellow, 

 subsessile, in a spreading erect corymb. Petals erect, linear, twice length of 

 calyx. Stamens glabrous. 



Stony hills and waste places, fairly common. May-July. 



The small, bright yellow flowered S. acre L, is much less common in the 

 south than in England. S. reflexum L. is fairly common on walls and stony 

 places in les Alpes-Marit. 



S. sexangulare L. (a small plant with pale yellow flowers in a slender 

 corymb and small linear obtuse close-set leaves) grows here and there in the 

 Maritime Alps, and the glandular S. villosum with pink flowers is recorded from 

 damp meadows near Ampus in the Var. The true villosum L. is unknown 

 in the Mediterranean district and this is the variety pentandrum G.G. 



SEMPERVIVUM L. 



S. tectorum L. House-leek. Sub-species S. calcareum Jord. Ro- 

 bust, at least a foot high, stem springing from a dense rosette of large obovate 

 oblong leaves, ciliate, suddenly narrowed into a mucro. Stem-leaves oblong, 

 submucronate. Flowers rose, in a long dense spiky corymb. Corolla star-shaped, 

 petals twice as long as the 12 sepals. 



Here and there on rocks in the montane region. July-August. 



S. arachnoideum L. Cobweb House-leek. Rosettes with lanceolate or 

 obovate leaves, abruptly acute, covered with short glandular hairs, stiffly ciliate, 

 bearded at apex with radiating web-like hairs, uniting the ends of the leaves. 

 Petals narrow lanceolate acuminate, 3 times length of calyx, rose-red with a 

 darker streak. Stem and stem-leaves often red. 



Rocks in the Alpine and mountain districts (May-July) descending in the 

 Var to Moriere above Sollies-Toucas, the summits of la Cabriere, etc. 



SAXIFRAGACE^E. 



Ovary 2-celled ; styles 2. Stamens 10. Petals 5 SAXIFRAGA. 



Ovary i-celled ; styles 2. Stamens 8 or 10. Petals o CHRYSOSPLENIUM. 



Ovary i-celled ; stigmas 3-4. Stamens 5 ; petals 5 PARNASSIA. 



SAXIFRAQAL. 



S. tridactylites L. Rue-leaved Saxifrage. A small annual pubescent 

 viscous species, often reddish. Root-leaves entire or 3-lobed, spathulate, stem-

 pedicels. Sepals erect, elliptical. 



Old walls, rocks, etc., common, especially on limestone. March-May. 



S. granulata L, Meadow Saxifrage. Root-stock reduced to a cluster of 

 small bulbs. Stem erect, 6-18 in. , branched and many-flowered above, pubescent 

 glandular. Leaves petioled, reniform, palmately lobed, cauline sessile. Flowers 

 white, rather large, campanulate in terminal cymes. Calyx-lobes erect obtuse, as 

 long as tube. Capsule with slender beaks. 



Damp, shady places in the hills and lower mountains. April-June. 



S. aizoides L. Yellow Saxifrage. Stems leafy, bearing a many-flowered 

 racemose cyme, but often only 2-3 flowered, hairy at summit. Leaves glabrous, 

 fleshy, grass-green, nerveless, entire, linear, mucronate, more or less ciliate,
