weeping whip-like branches and small white fruits like mistletoe 
berries. 
Next day we started by the first tram (7 a.m.) for Laguna, and 
walked from there to the woods of Las Mercedes. There was a 
good deal of the fragrant yellow-flowered Sparteum junceum on the

before the Spanish Conquest, lived mostly in caves, and the custom 
has persisted to the present day. The best known cave-dwellings 
are those of Atalaya in Grand Canary. 
A fine Sempervivum with greenish-white flowers was fairly common 
on the dry stony hill-side, and there was a good deal of a shrubby 
plantain (Plantago arborescens), which formed much-branched bushes

in outlying parts of the wood. 
which ascends to the top of the trees, where it produces dense 
masses of flowers. The stems of old plants become very corky, and 
one that we measured was 12 inches in circumference at the base. 
A pretty Senecio (S. appendiculatus) with white ray and_buff- 
coloured centre was very common in the wood. Forty-five numbers 
of plants were collected during the day, and photographs were taken 
of some of the more characteristic species. 
We left for England on the evening of the following day (June 
19th), and arrived at Southampton on June 27th. 
Over six hundred numbers of plants were collected during the 
expedition, and about fifty photographs were taken. The scientific 
results will be published elsewhere as soon as the collection has been 
worked out.
