3. The Mediterranean and Orient Region includes Spain, 
southern France, Italy, Greece, Asia Minor, Persia, the 
Punjab, and Africa and Arabia north of 24 0 N., together 
with the Canaries, Azores, &c. It is very closely allied to 
the preceding region, and possesses a very similar vegetation 
( cf Zone III. above). A few palms occur here, e.g. 
Chamaerops and the date-palm (Phoenix). There are many 
Cruciferae, Umbelliferae, Labiatae, Tamaricaceae, &c. : other 
characteristic forms are Myrhis co?nmunis (myrtle), Olea 
enropaea (olive), Erica arborea , Quercus Llex , Finns Pinea 
and other Conifers, Plat anus orient alis (plane), Laurus 
nobilis (bay), Pistacia Lentiscus (mastic), Arbutus unedo , 
Castanea vulgaris (chestnut), &c. Among genera with a 
large proportion of their species endemic in this region are 
Anthemis, Astragalus, Allium, Campanula, Centaurea, Cou- 
sinia, Hypericum, Salvia, Silene, Verbascum, &c. 
4. The Eastern Asiatic Region includes the rest of 
China, with Corea and Japan, and possesses many endemic 
forms, e.g. the Conifers Cryptomeria, Ginkgo, Biota, &c., 
many Araliaceae, Lardizabalaceae, Menispermaceae, Magno- 
liaceae, Sapotaceae, &c. 
5. The Central North- American Region is the region 
lying between region 1 and the tropical regions of Mexico 
and the West Indies ; it includes the United States with the 
exception of a part of New England, Washington State and 
Oregon, and includes also a portion of Canada as far as the 
Saskatchewan. The climatal conditions resemble those of 
the Mediterranean region (cf. Zone III.). The flora includes 
many Compositae, Hydrophyllaceae, Polemoniaceae, Nycta- 
ginaceae, Chenopodiaceae, Polygonaceae (§ Eriogoneae), &c. 
Sequoia and other Coniferae (q.v.) characterise the Califor- 
nian flora ; the drier States west of the Mississippi have a 
xerophytic flora — Cacti or Yuccas in some parts, Artemisias 
and other halophytes elsewhere (cf. above). Juglans, Carya, 
and other trees mark the Eastern States. 
II. Tropical Group. 6. The Tropical African 
Region includes all Africa and Arabia south of region 3, 
except the Cape-Colony region and the islands on the east 
side. Palms (notably Elaeis guineensis , Raphia, Borassus),
