A THE JOURNAL OF BOTANY 



coast lands is found, at a heiglit of from 2000-4000 ft., the 

 ' Monte Verde,' or belt of evergreen woods, consisting largely 

 of LaurmecB and Myrica Faya, with species of Ilex, Erica, Arbutus, 

 Viburnuvi, and Cistus. The deep, rocky ravines called ' bar- 

 rancos,' which everywhere furrow these wooded slopes, contain 

 the springs which furnish most of the scanty water-supply of the 

 island, and here, in dampness and shade. Mosses and Hepatics 

 flourish luxuriantly. In the three magnificent ' barrancos ' of 

 Eio, Badajos, and Ahavingo, all easily accessible from Guimar, 

 most of the Mosses in the following list were collected. To the 

 Monte Verde succeed the scant remains of the pine-forests, still 

 lying within the influence of the cloud-belt. Above the upper 

 limit of the Pinar sterility reigns, vegetation being almost restricted 

 to certain endemic Leguminosce. There is here intense dryness 

 of the atmosphere, strong insolation by day, a great difference 

 between day and night temperature. Upon the Peak, at the 

 shelter-hut (10,700 ft.), no Mosses w^ere noted, and w^ith difficulty 

 a very few Lichens were found. At the Rambleta (11,700 ft.) 

 the only moss met with was Grimmia tricliopkylla, maintained by 

 the moisture due to condensation of steam escaping from a volcanic 

 vent. Short visits were paid to some specially favourable locali- 

 ties, as to the laurel-woods of Teno at the w^estern extremity of 

 the island, the little patch of forest at Agua Garcia, and the 

 luxuriant evergreen woods of Las Mercedes and Taganana, which 

 support a cryptogamic flora unequalled elsewhere in Teneriffe. 

 All these localities are situated upon the older formations, which 

 evidently retain much more moisture than do the later volcanic 

 deposits which now cover the greater part of the island." 



For assistance in drawing up the following list I am greatly 

 indebted to Mons. J. Cardot. 



Ceratodon 'purjmreus Brid. Pinar, above Ladera, Guimar (no. 3). 



Cynoclontium Bruntoni B. & S. Pinar, above Ladera, Guimar 

 (no. 12), c. fr. The capsule is more symmetrical, smoother, and 

 with less distinct neck than in our usual European form, and the 

 leaf-cells more pellucid. 



Leiicobryum glaucuin Schp. Taganana (no. 41). 



Fissidens serrulatus Brid. Agua Garcia (no. 42), c. setis. An 

 unusual form, having the cells practically smooth. — F. adiantoides 

 Hedw. Agua Garcia (no. 40). 



Gymnostomum calcareum Bry. germ. Monte Yzana, Guimar 

 (no. 7). — Var. muticum Boul. Barranco del Eio, Guimar (no. 15). 



Weisia crispata (Bry. germ.) Jur. Barranco del Rio, Guimar 

 (no. 17), c. fr. New to the Canaries. The peristome in several 

 of the capsules is more highly developed than usual, the teeth red 

 and quite conspicuously protruding beyond the capsule mouth ; in 

 other capsules it is paler and much shorter. The leaves are 

 stoutish, with wide points and strong nerve, often cucullate, and 

 wath the margins widely enrolled. 



Timmiella anomala Limpr. Barranco, above Arafo (no. 8), 

 c. fr. Barranco del Rio, Guimar (no. 23), c. fr.
