(2) In the hinterland of Monrovia, within a radius of 20 miles 
of a place called Karkatown. 
(3) In the basin of the Sinoe River, from Sinoe as far as 
Soyos’ Town in the Kuru (or Kulu) country, about 80 miles 
inland, in March and April, during a period of extremely hot 
weather. “ Physical features of the country flat and covered with 
dense virgin-forest, except where native gardens have been made 
and where the forest-growth rushes up with amazing rapidity. 
Rainfall very abundant; climate moist and humid all the year 
round. Country under water in very wet weather and travelling 
almost impossible, as no roads exist, or even traees of forest 
footpaths.” 
As there are no special labels with the specimens, I am 
obliged to give the localities in a summary way. The collections 
comprise over 260 species. To these Mr. D. Sim, an employee 
in the service of the Monrovian Rubber Company, also con- 
tributed; but as I have already described the novelties dis- 
covered by him in * Flora of Tropical Africa,’ vol. iv. pp. 595- 
610, his name does not appear in this paper*. Out of these 260 
aud odd species I have to record 4 new genera and 58 new 
species, or, including those described previously, 67 new species, 
certainly a very considerable percentage. This will, however, 
appear less surprising if we bear in mind that Liberia is, perhaps 
with the exception of the French Ivory Coast, the least explored 
part of the West-African littoral, and that up to 1904 not more 
than about 200 species were known from the whole territory 
of the Republic, the area of which is estimated at 36,800 square 
miles, or a little more than two-thirds the area of England. 
Moreover, almost the whole of the earlier collections were made 
at Grand Bassa and Cape Palmas, that is outside the districts 
explored by Whyte and Sim. That Liberia is likely to yield a 
great many new species is also suggested by the results of 
Mr. Dinklage’s excursion to Grand Bassa and Cape Palmas in 
1898, numerous new species having been described by the Berlin 
botanists from his collections. At the same time, it must be 
remarked that all the new species described here belong to types 
of a higher order, characteristic of the West-African flora, 
or extending over larger parts of the tropics. As might be 
expected, Liberia, to judge by the little we know, presents itself
