CRITICAL NOTES ON SOME SPECIES OF CERASTIUM 325 



from 2-4 ctim. in height, collected by Gandoger (Fl. Hisp. exs. 

 n. 410 [1896]), in pine-woods near Bullias in Murcia. Restricted to 

 Valentia, Murcia, and Aragon, in Spain, on sandy soil. Seems to be 

 most nearly allied to G. pumilum. Mr. A. Bennett is, however, 

 disposed to consider the latter (in its typical form) to be practically 

 an endemic British plant, as it grows only on chalky banks in the 

 south of England, and never on a sandy soil. It would be interesting 

 to grow G. Gayanum on a chalky soil, and see what happens.

a virulis nobis (forma typi). — Folia laete viridia lineari-lanceolata 

 nervo valido instructa, sparsim pubescentia. Caules, pedicelli cum 

 sepalis dense glanduloso-pubescentes subviscidi. 



Hab. Gibraltar ; in abundance in clefts on the east side of the 

 rock, in smaller quantity on almost every otber part of the rock. — 

 Spain ; Sierra de Agua, near Carratraca, in prov. Malaga. 



(3 niveo-tomentosum nobis: = G. Boissieri Gren. Monogr. 67 

 (1841). — Folia ovato-lanceolata cum caulibus molliter niveo-tomen- 

 tosa. Pedicelli cum sepalis breviter glanduloso-pubescentes. 



Hab. In the montane and alpine regions of Spain (chiefly in the 

 south), Marocco, and Algeria. Up to 2700 m. on Sierra Nevada. 



y lanuginosum nobis : =G. Boissieri var. lanuginosum Gren. t. 7. 

 — Totum piloso-lanatum, pilis glandulosis, etiam in pedicellis 1-3- 

 floris et sepalis crispato-lanatis. 

 Hab. Sardinia. 



This is " C. lineare " of Sardinian botanists, but not of Allioni, 

 which is a plant of the Alps of Piedmont. Cf. also Barbey, Fl. Sard, 

 comp. 219.

 (1831), non ex Gren. Monogr. 67.— Inferne glabrum, superne tomen- 

 tosum, pilis crispatis non glandulosis. Folia primaria viridia vix 

 subtomentosa, novella autem fasciculatim ex axillis prodeuntia dense 

 tomentosa, reque ac pedunculi calycesque. Capsula ovoidea, brevior 

 quam in a. 



Hab. Corsica. Mountains above Bastia (Salis, 1832, ex herb. 

 Gay, in Herb. Kew.), and probably elsewhere in the island.^ 



Syn.— G. repens (non Linn.) Salis in Flora, xvii. Beibl. ii. 72 

 (1834). Described from Salis' original specimens, which he sent to 

 Gay. To this var. I also refer the C. Boissieri of Briquet's Prodr.
