296 BOTANICAL INFORMATION. 
herbarium distributed by Wallich, besides a great number. of 
either less important collections or named ones, which are 
quoted for all but common species, and even in these the 
numbers of the unnamed collections are generally given. The 
value of these unnamed but numbered sets is thus very con- 
siderably enhanced, and it would be of great use to science, 
and very advantageous to the interests of collectors, if they 
were to transmit to Prof. de Candolle, complete sets of those 
portions of their collections, which are not yet contained in 
the Prodromus. 
The Primulacee by M. Duby (editor of De Candolle and 
Duby's “ Botanicon Gallicum") follow the Lentibulariee ; 
they had long been the object of his special study, so far as 
other avocations permitted, and residing at Geneva, he could 
avail himself of the materials possessed by DeCandolle; so that 
whatever may be the opinion of local botanists on the limits 
he may have ascribed to some of the much contested species 
of Primula, Cyclamen, ete. the enumeration he has here given 
will be found to afford a natural distribution and intelligible 
characters both for genera and species. Excluding the two 
doubtful plants or rather riddles of Mr. Bowditch, mentioned 
at the end, the Order consists of twenty-three genera (num- 
bered by a misprint as 21), and among them the only two of 
which the propriety may be doubted are Pelletiera, St. Hil. 
which is so exactly like Asterolinum that it ought perhaps to 
be considered a reduced form of it, and Micropyzis, Duby: 
not sufficiently distinct from Centunculus, the habit being pre” 
cisely the same, and the number of parts in the flower, four 
or five, does not appear to be quite constant in some species. 
Among the species enumerated, a Javanese Hottonia (H. ses- 
siliflora, Vahl) is extraordinary, and it would be well for 
those who have an opportunity of examining the plant to 
ascertain whether there is not a slender dissepiment to the 
ovary, and four, not five, stamens and valves to the capsule, 
in which case it must, like the H. indica, Linn. be referred 
to Limnophila. i PE. 
The Myrsineacee were originally undertaken by Alphonse —
