sorts, similar to those received in this country from Malta, are 
unknown in the Canaries. 
Walnut {Juglans regia). — This tree is fairly common. It 
deserves to be still more largely planted. The fruit is cured and 
shipped to a small extent. 
Loquat (Eriohotrya jaijonica). — The Japanese Medlar, or 
Loquat, known locally as " Nespero," is one of the regular fruits 
of the country. They are usually of good quality, but many 
self-sown seedlings produce poor fruits. The best varieties with 
only one seed should be carefully cultivated. The Loquat makes 
excellent jelly. 
Papaw {Carica Papaya). — The Papaw tree, with its usually 
single stem surmounted by a crown of large palmate leaves, is 
not uncommon in the lowlands. The fruit is like a Melon in 
flavour, but, except in the very best sorts, is apt to be insipid. 
The juice has the singular property of rendering flesh tender. 
From the milk is prepared vegetable pepsine. 
Olive {Olea europcea). — Many large Olive trees arc scattered 
over the country. They appear to bo semi-wild sorts, of little 
value commercially. If it were proposed to cultivate Olives of 
the best sorts it would be necessary to introduce grafted trees, 
and select those yielding large fruits known as Spanish Olives. 
Chayota (Sccliium edule). — This is a pear-shaped fruit witli 
a single seed borne by a large climber with the habit of a 
Vegetable Marrow. In fact, the fruit closely resembles a 
Vegetable Marrow in flavour, and is used in the tropics as a 
substitute for it. It is a native of South America. There are 
two well-marked varieties, green and cream-coloured. The 
Chayota, Chocho, or Cln-istophinc, is sometimes imported into 
this country from Madeira. It sells well during the winter 
months, and only requires to be more widely known to be in still 
greater demand. 
Amongst the Passion-fruits the most common is the Sweet- 
cup (PasKljlora cdulis). This is sometimes, but erroneously, 
called Granadilla. The fruit Is the size of a small apple, purple 
outside. The plant grows very readily everywhere. The true 
Granadilla [V. qiiadram/ularis) is borne by a very vigorous 
climber with a square stem and large oblong leaves. The fruit 
is green, as large as a Vegetable Marrow, and 1)11(^1 witli a jolly 
in which are immerous seeds. A plant of this was noticed grow-
