2. AVest I n d i e s . The Bahamas and St. Domingo and the
Antilles have been very imperfectly explored, except Dominica,
Trinidad, and Alartinique. On tlie mainland, Honduras, Nicaragua,
and the coast region of Alexico, the Mosquito shores and
'Guatemala offer rich fields for hotanical research.
3. I n d i a n O c e a n . The Seyclielles, Ammirantes, Madagascar,
Bourbon, Socotra, St. Paul’s, and Amsterdam Islands, Prince
Pdward’s, tiie Crozets and Marion groups. Of tlie E. African
coast to the north of Natal no part is well explored, and the
greater part is utterly unknown botanically.
4. P a c i f i c O c e a n , 1. N. T em p e r a t e . Collections are
Avanted from N. Japan and tlie Ivuriles and Aleutian Islands.
2. T r o p i c a l . Considerable collections liave been made only in
the Sandwicli Islands, Fiji Islands, Tahiti, and NeAV Caledonia;
from all of wliich more are much wanted. The Marquesas, New
Hebrides, Marshall’s, Solomon’s, and Caroline's, together with
all tlie smaller groups, are still less known. Of the American
continent, the Californian Peninsula, Mexico, and the whole
coast from Lima to Valparaiso, are but imperfectly known. Of
the small islands off the coast, Juan Fernandez and the Galapagos
alone have been partially botanized. 3. S. T em p e r a te .
Juan Fernaiidez, Masafucra, St. IVlix, and Ambroise, Pitcairn,
Bounty, Antipodes, Emerald, Macquarie Islands.
5. I n d i a n A r c h i p e l a g o . Java alone is explored, and the
Pliilippines very partially ; collections are especially wanted
from all tiie islands east of Java to tbe Louisiade and Solomon
Archipelagos, especially Lombok and New Guinea. Siam,
Cochin China, and ' the whole Chinese sea-board want exploration.
6. A u s t r a l i a . All the tropical coasts are very partially
explored.
Photographs or careful drawings of tropical vegetation often
convey interesting information, and should contain some reierence
to a scale of dimensions.
An inquiry of much importance, for which the present
Expedition affords a favourable opportunity, is that into the
vitality of seeds exposed to the action of sea-Avater.
Observations should especially be made on tlie fruits and
seeds of those plants Avhich liaAm become widely distributed
throughout the tropical regions of the Avorid, apparently without
the intervention of man; but further ohservations on other
plants of different natural orders may be of great value with
reference to questions of geographical distribution.
The following Instructions have been drawn np for tlie
botanical collectors as to objects of special attention at particular
places :—-
Porto Pico.—In collecting, distinguish the plants of the Savannahs
from those of the mountains, which, if possible, should be
ascended. The palms and tree-ferns are quite unknown; marine
algie also are Avanted.
Cape de Verdes.— Mdke for the highest peaks, where the
vegetation is peculiar and analogous to that of Madeira and
the Canaries.
Fernando de Noronha.— 'L&D.d if possible. Very remarkable
plants are said to occur, different from those of Brazil.
Trinidad.—A complete collection is required. A tree-fern
exists, but the species is unknown.
Prince Edward’s Island and Crozets.—Two spots more interesting
for the exploration of their vegetation do not exist
upon the face of the globe. Every effort should be made to
make a complete collection.
Kerguelen’s Land.—A tiiorough exploration should be made,
and the Cryptogamic plants and algae diligently collected. The
Antarctic Expedition was only there in midwinter; flowering
specimens of Pringlea are Avanted.
Auckland and Campbell Islands.—The floras should he well
explored.
South Pacific and Indian Oceaqis.—Attend to general instructions,
more especially as regards palms and large monocotyledons
generally. Marine algae are said to be scarce, and sliould
be looked for all the more diligently. In the North Pacific,
south temperate algae are said to prevail.
Aleutian Islands.—Collections are particularly wanted.
Every effort should be made to laud on island.8 between
