30 BOTANICAL NEWS. 



interesting is ^axifraga flondenta^ a plant which seems to be confineil 

 to a limited area of these mountains. It is said to have been first 

 discovered by an English tourist in 1824, when specimens were com- 

 municated to Prof. Moretti, of Pavia, who wrote a short description 

 of the plant. In 1856 it was rediscovered and other localities have 

 since been added, and it now seems to be not unfrequent at an altitude 

 of from 7500 to 9000 ft., all the stations, however, being within four 

 or five miles of the original habitat. The author has discovered two 

 fresh stations, viz., on rocks with northern exposure near the CoUe de 

 Fenestrelle, and at the Colle de Cerise. Out of about 100 plants only 

 one was in flower ; this has been figured in the Botanical ^Magazine 

 tor July last (tab. 6102). The rosettes probably attain a great age 

 before flowering. It is distinct from any Saxifrage by having three 

 instead of five styles and carpels, and should perhaps form a new genus. 

 The author then goes on to describe the botany in the neighbourhood 

 of the Colle de Tenda (6158 ft.). Genista cinerea is abundant in the 

 valley of the Roja, which is also a habitat for Cytisus Ardouini, Saxi- 

 fraga lantoscana, Micromeria Piper ella, and other rarities. The fol- 

 lowing are to be found near the town of Tenda : — Silene cordifolia, 

 Mcerhingia papulosa, Fritillaria involucrata, Asperula hexaphylla, Pas- 

 serina dioica, Saxifraga cochlearis, &c. Between Tenda and Nice, 

 Primula Allionii, Potentilla Saxifraga, 3I(erhingia danjphylla. Cam- 

 panula macrorhi%a, Saxifraga lantoscana, and others may be gathered. 

 — " Extracts from letter of Mr. Gilbert regarding the vegetation of 

 Moulmain." Mention was made of a very large Platycerium (probably 

 P. hiforme) with fronds measuring 15 — 18 feet; and it was noted that 

 Adiantum Parishii is only to be found on stalactite surfaces of rocks.
