Ascheeson, P.—Nachtrag zur Flora von Labrador ("Flora," 1860, 369–70). In a collection of 152 species gathered by Lundberg, near Nain, in Labrador, Dr. Ascherson finds about 36 species of flowering plants and ferns which are not in the lists of Schlechtendal ("Linnæa," 1836, p. 76), or Martens (Mün. Denk. Regensb. Bd. iv. i. 1).
Babington, Chaeles C.—Flora of Cambridgeshire, or Catalogue of Plants found in the county of Cambridge, with references to former catalogues, and the localities of the rarer species.—London, 1860, 8vo., 327 pages. A chapter on the topography of the county, with map, and a tabular summary of the distribution of the species, are pre- fixed to the catalogue. An appendix contains observations upon several critical species and genera (Thalictrum saxatile, Papaver dubium, Viola canina, Arenaria serpyllifolia, Rulus, Serrafalcus, and Triticum), a list of species characteristic of the vegetation of the Fens, and another of species believed to be lost to the Cambridge Flora. A short account is also given of the range of Cambridge species in Britain beyond the limits of the county.

Baillon, N.—Recherches Organogéniques sur la Fleur Femelle des Conifères. Presented to the Academy of Sciences, April, 1860. The author bases his views upon an extended organogenic study of the floral organs of the order. The development of the bracts, "scales," and female flowers, is detailed from Taxus baccata, Phyllocladus rhomboidalis, Torreya nucifera, Thuja, Pinus resinosa, Salisburia, and Cupressus.
In Pinus resinosa, L., the cone presents, in its earliest stage, a cylindro-conical axis, bearing numerous unequal alternate bracts, the development of which is arrested at an early period. These, the author regards as the only appendicular organs of the cone. In the axil of each bract originate minute cellular, vertically compressed, obtuse processes, which eventually become the trilobate flattened "scales," bearing a pair of female flowers upon the lower portion of the lateral lobes. The median lobe, in the process of growth, ceases to be the apparent apex of the scale, becoming, by a partial arrest, a slightly incurved tooth-like projection borne near the middle of its inner side. Dr. Baillon regards the scale as a metamorphosed branch. Each flower originates with the rudiments of a pair of minute car-
