SAXIFRAGACE^E 109 



crowded at apex of the shoots. Petals linear-lanceolate, yellow or orange or 

 sometimes deep orange-red. Stamens orange-yellow. 



Damp places in the Maritime Alps, descending e.g. to San Dalmazzo di Tenda 

 (2280 ft.). June-August. 







S. cuneifolia L. Glandular at top, 6-12 in. high. Rosette leaves petipled, 

 obovate cuneate, very obtuse, leathery, glabrous and shining, toothed with a 

 narrow cartilaginous margin. Flowers white, in a narrow panicle. Sepals re- 

 flexed ; petals spreading, oblong, punctuated with yellow at base. Capsule twice 

 length of calyx. Flowering stem leafless. 



Damp rocks and in woods of the montane region of Alpes-Marit., descending 

 to the district above Menton, etc. June-July. Common in the chestnut zone in 

 Liguria. 



S. lingulata Bell. Stem 6-18 in. long, glabrous, often drooping, branch- 

 ing from the middle or sometimes lower, with several small linear and sometimes 

 indented leaves. Rosette leaves, linear-oblong, elongated, channelled above, 

 rather pointed at apex, thick, entire, with an encrusted indentation at the curved- 

 in margin. Rosettes rather loose and erect. Flowers milk-white, in long and 

 rather unilateral panicles, with branches of 2-6 flowers. Calyx glabrous, but 

 slightly rugged, with lanceolate-obtuse lobes. Petals ovate, wedge-shaped. 

 Stamens subulate. 



Limestone rocks in the mountains, very local. Common on the Col de 

 Tenda and on the mountains above Menton and Grasse. June-July. 



In the Var it grows on the Marges escarpments, and was recorded from 

 Sainte-Baume by Robert and Hanry, but the plants we saw growing at Sainte- 

 Baume are very glandular and identical with specimens from the Mont de la 

 Chens (N. of the Var) in Herb. Jahandiez which agree better with S. lantos- 

 cana. 



S. lantoscana Boiss. et Rent. Stem usually shorter than in S. lingulata 



of which it is sometimes considered a variety or sub-species. Rosette- leaves 

 linear spathulate, broader towards apex, with white calcareous patches, obtuse 

 and shorter than in lingulata and not channelled. Flowers milk-white, with 

 fine lines of red dots. Inflorescence more or less unilateral. Calyx campanulate, 

 with lanceolate-obtuse teeth. 



Limestone rocks in the district round St. Martin Lantosque in the Maritime 

 Alps, at Mont de la Chens in the Var, at Sainte-Baume with S. Aizoon Jacq. 

 (fide H.S.T.), and probably in Liguria. The last species is very rare in the Var. 



See " Kew Bulletin" (1911), No. 3, and " Gard. Chron.," 16 March, 1912, 

 December, 1874, 23 August and i November, 1913, for various notes on these 

 two Saxifrages. 



S. cochlearis Rcichb. Stem 4-12 in., glandular except at summit, slender, 

 reddish-brown, branching above middle into a usually short and sometimes 

 glandular panicle, with usually 3 flowers on each branch. Rosette-leaves quite 

 short, broadly linear at base and suddenly dilated into a suborbicular, spoon-shaped 

 apex, coriaceous and rugged in texture, encrusted at margins with lime. Stem 

 leaves narrowly oboval, very small and slightly glandular. Flowers milk-white ; 

 petals obovate, wedge-shaped. Calyx glandular, with obtuse lobes. 



Sub-Alpine limestone rocks in the Maritime Alps and adjoining mountains 

 of Liguria, where it descends to about 1300 feet at Buggio in the Nervia valley, 

 and ascends to 5500 feet. Also found on Mt. Mulacd above Menton. Endemic 

 in this district. June-July. 



S. hypnoides L. Mossy Saxifrage. Rosette leaves 3-5 cleft, glabrous or 

 more or less ciliate. Leaves of barren shoots entire or'3 cleft, narrow, linear and 

 pointed. Stems 3-6 in. long, with very few linear leaves, and from 1-6 rather 

 large white flowers. Calyx-segments pointed and not one-third as long as 

 petals. 



Moist rocky places in the limestone mountains of the Var ; not uncommon. 

 May-June. Apparently this is its most southern and eastern limit in Europe.
