Among the species that generally 
bit these situations, are Convolvulus

the former, the name of Toscala is given 
wherever ic tufaf i is, 
second kind of districts are called Malpais. 
Examples of both may be seen in Téné- 
riffe, near Teno, in the vicinity of Sainte 
Croix, and in the vallies of Guimar and 
Orotava, and still more decidedly towards 
the North of the island, at the Point del 
Hidalgo, where the maritime hillocks are 
covered with species of Artemisia, Laven- 
der, and Thyme, with other aromatic 
plants, most of them being woody and 
having ashy grey foliage. Among these 
are Artemisia argentea, Lavandula pin- 
nata, Sideritis Canariensis, Thymus Ca- 
lamintha, and T. Teneriffe, Plantago ar- 
borescens, Stachys Canariensis, &c. 
The uncultivated part of the valley of 
Guimar mentioned above, offers one of the 
best types of the vegetation peculiar to the 
Toscalas ; there we found Notoceras Cana- 
riensis, Gnaphalium cauliflorum, Buph- 
thalmum sericeum, Fagonia Cretica, Ai- 
zoon Canariense, Saccharum Teneriffe, 
Linaria scoparia and L. Elatine, Teu- 
crium pseudo-iva, Plantago Coronopus, 
Micropus pygmeus, &c. In the same lo- 
cality first appear Prenanthes spinosa and 
Cneorum pulverulentum, both of which oc- 
cur far more abundantly in the southern 
district of the island, where they grow 
together with Zygophyllum | .Fontanesit 
(nob.), Euphorbia balsamifera, Aloe vul- 
garis and Justicia hyssopifolia. 
On the Malpais the following plants are 
combined with some of those already men- 
tioned; Polycarpea gnaphalodes, Achy- 
ranthes argentea, Paronychia Canarien- 
sis, Salvia Aigyptiaca, Asparagus umbel- 
latus, Forskülea fruticosa, Echium acule- 
atum, Frankenia ericefolia, Rumez spi- 
nosus, Bupthalmum maritimum, Lycium 
Afrum, Datura Stramonium, and D. Me- 
tel, Hyoscyamus Canariensis, Mesembry- 
anthemum nodiflorum and M. chrystalh- 
num, (which latter plant has been natu-” 
ralized in these regions); and then come
