ANDEESSON ON GALAPAGOS-OABNES VEGETATION. 369 
the circumstance that many Monocotyledons wither up and wholly 
disappear in the dry season, and partly because many of them have 
very inconspicuous flowers. Grasses and sedges, indeed, are often 
quite neglected by non-botanical collectors. Of the total Phanero- 
gamia (332) 174 species are, as stated above, endemic. This 
extraordinarily large proportion of peculiar species presents itself 
under a very remarkable aspect when we inquire into the relations 
of the different Islands to each other in respect to the endemic 
plants. Each Island, as Dr. Hooker observes, stands, in this regard, 
in nearly the same relation to the rest of the group that the whole 
Archipelago bears to the American continent and the Polynesian 
Islands. Eor example, of the above 174 peculiar Galapageian species, 
only five are common to the five Islands, the botany of which has 
been hitherto partially explored. Very few indeed are common to 
any four, three, or two of the Islands, while Chatham possesses 26, 
Charles 40, Indefatigable 9, Albemarle 22, and James 26 (38 in 
Dr. Hooker’s Essay), peculiar to these respective Islands. The 
species common to five Islands or fewer, the Islands being specified, 
are tabulated. 
The relative proportions of the prevailing Natural Orders indi¬ 
cated by Dr. Hooker are necessarily altered by the recent additions. 
The largest 10 stand thus :■— 
Composites number 40 species, constituting 1 /8th of the Phane- 
rogamia; 29 species (and 22 genera) are endemic; of the remaining 
11, 8 are North American. 
Leguminosee, 30 species; l/10th of Phanerogamia; 7 endemic. 
No new genera. 
Gramineas, 32 species ; over l/10th Phanerogamia ; 15 are 
endemic; 14 of the remainder common to America and the Antilles. 
Euphorbiacese, 29 species. l/12th Phanerogamia—a relatively 
larger proportion than in any other area ; 22 are peculiar; of these 
Charles Island possesses 12, Chatham 12, Albemarle 9, James 6, In¬ 
defatigable 1. 20 species are confined each to a single Island. 
Amaranthacese, 18 species; l/18th Phanerogamia, 13—15 are 
peculiar. 
Eubiacese, 16 species. 
AsperifolieaB (Tournefortiese, PleliotropesB, &c.), 13 species. 
Solanacese, 12 species. 
Cyperacese, 12 species. 
Convolvulacese, 12 species. 
The Galapageian species Dr. Hooker referred to two main types : 
(1) the West Indian (including Panama), which he stated to include 
nearly all the plants common to other countries; and (2) the Mexi¬ 
can and temperate American, under which “the great majority” of 
the peculiar species rank. 
Dr. Andersson’s collations extend and confirm the correctness of 
this reference. Of the Continental species growing in the Galapagos, 
l/3rd, or a total of 63, are common to the Old as well as to the New
