Notes on the Plants observed during the Roraima 
Expedition of 1884. 
By the Editor. 
S was expected, the plants collected on the way 
to Roraima, and especially about the mountain 
itself, during the recent expedition to, and first 
ascent of, its summit, now that they have been examined 
and catalogued at Kew, have proved of great interest. 
Several specialists have most kindly lent their aid in 
examining and determining these plants. While Profes- 
sor OLIVER undertook the bulk of the collection, Mr. 
J. G. BAKER, besides determining a few of the petalloid 
monocotyledons, has, aided by Mr. G. S. JENMAN of 
British Guiana, worked out the ferns ; Mr. H. N. 
Ridley of the British Museum the Orchidiaceae and Cype- 
raceae ; and Mons. E. MARCHAL the Araliaceae. Again 
Dr. ENGLER has described a new Moronobea, Mr. 
BROWN a new Aroid, and Mr. Mitten has named the 
Muscales. Lastly, Dr. Maxwell Masters has supplied 
a note on two Passiflorae, perhaps new, but imperfectly 
represented. In all, fifty-three new species and three new 
genera have been described by these various workers. 
The number of species collected would probably have 
been greater but for the extreme difficulty of drying 
plants in so excessively damp a climate as that of 
Roraima, and but for the fact that the other very serious 
labours inseparable from the ordering, and keeping in 
order, of such an expedition greatly curtailed the time I 
was able to devote to the preparation of botanical speci-
