vertical distribution of these small water-plants in India, the 
individuals and species decrease in number as we ascend the 
mountains. At Java, 5,000 feet above the sea, where lakes and 
pools abound, scarcely any duck-weeds exist. In Laboul, however, 
Lemna minor, the only species known in that district, ascends to 
9,500 feet.* | 
The Herbarium of the British Musewm.—From the official 
report of the Botanical department published recently, we learn 
that during the year 1865 the following additions have been made 
to the collection :—1,500 species of plants in the form of a her- 
barium ; 269 species of plants from the Shetland Islands; 250 
British fungi; 5 microscopic fungi; a monograph of British 
Cladoniz, containing 80 species; 269 species of Swedish plants ; 
200 plants, forming cent. 384 and 35 of Billot’s ‘ Flora Gallice ;’ 
1,000 species from the Tyrol; 100 Italian species, being fasciculi 
23 and 24 of the ‘ Erbario Crittogamico Italiano;’ 400 of the 
rarer plants of Sicily; 76 roses; 273 European mosses; 100 
fungi; 130 alge; 30 microscopic slides of Diatomaces ; 1,078 
species of South African plants; 1,600 from the Zulu country ; 
2,850 from Venezuela; 2,127 from Cuba; 2,000 garden specimens 
from Mr. John Smith’s Collection; and 100 fruits and seeds from 
Mexico: altogether, 15,027 species, the accumulations of ‘a single 
year. 
Mr. M. C. Cooke publishes a valuable paper on leaf Spherie, 
in the ‘Journal of Botany, August, 1866, containing descriptions 
of 28 species, eleven of which are new to science, and therefore 
described by Mr. Cooke for the first time. Eight of these novelties 
were collected by Dr. Edward Capron, of Shere, Surrey, and the 
remaining three were gathered by Mr. Cooke. All interested im 
the study of microscopic fungi will give due credit to these gentle- 
men for thus contributing to our knowledge of leaf Spheriz. The 
following are the names and habitats of the new species :— 
Venturia Myrtilli: on semi-putrid leaves of Vaccinium Myrtillus, 
Venturia lictfolia: on semi-putrid leaves of Holly. Spherella 
oblivia: on under-surface of dead Chesnut leaves. Spherella 
arcana: on dead leaves of Castanea vesca. Sphexrella simulans : 
on dead Oak leaves, Highgate, 1866. Sphezrella punctoidea: on 
upper surface of Oak leaves. Spherella millegrana: on upper 
surface of dead leaves of Hornbeam. Sphzxrella latebrosa: on dead 
leaves of Sycamore. Sphzrella Acerifera: on dead leaves of Acer 
campestris. Sphexrella inequalis: on dead leaves of Pyrus aria. 
Spherella Vaccinit: on semi-putrid leaves of Vaccinium Myrtillus.
