companies the leaf, obtains an oblique position. But he does not thus prove 

 that the tendrils are segments of a leaf or stipules, whilst if they are re- 

 garded as entire leaves, this may be proved by the earlier stage of develop- 

 ment, before the formation of any vessels (Wiegm. Archiv., 1846, p. 24). 



CRUCIFEILE. Barneoud has described the small group of the Schizope- 

 talese, to which, in addition to the principal genus (containing 2 species), 

 Perreymondia, n. gen. Barn, from Chili (with 4 species) belongs (Ann. Sc. 

 Nat. iii, 3, p. 165-8). The characters are limited to the divided petals and 

 the branched hairs, Perreymotidia not possessing the divided cotyledons, 

 but an ordinary notorrhizal embryo, and as this is the only difference, it can- 

 not constitute a distinct genus. Trautvetter separates Matthiola deflexa, Bg. 

 from the genus Matthiola, as Microstigma, Tr. (PI. Ross, imagines T. 25). 

 Nejw genera : Lyrocarpa, Hook. Harvey (Lond. Journ. of Bot. 1845, p. 76) ; 

 it has a panduriform silicule, and was discovered by Coulter in California ; 

 Dithyrea, Harv. (1. c. p. 77), allied to Biscutella, from the same source ; 

 Oxystylis, Torr. Erem. (Explor. Exp. and 1. c. p. 41), well characterised, 

 approaching the Capparidacesc, also from California ; Pringlea, Anders, d. 

 Hook. (Antarct. Voy. p. 238, pi. 90-1), the above-mentioned cabbage of 

 Kerguelen's Land. 



PAPAVERACEJE. New genera from California : Romneya, Harv. (1. c. p. 73), 

 principally distinguished from Papaver by the trimerism of the two outer 

 whorls ; Arctomecon, Torr. Erem. (1. c. p. 40), only differing from Papaver, 

 according to the description, in the strophiolate seeds. 



RANUNCULACE.E. Eor a notice of Barneoud' s work, the whole of which 

 has not yet been published (Compt. rend. 1845, ii. p. 352-4), see Link's 

 ' Physiological Report ' (p. 95). Cl. Gay has established two genera from 

 Chili : Psychrophila (Hist, de Chile Bot. i. p. 47, t. 2), separated from 

 Caltha and Barneoudia (ib. p. 29, t. 1, f. 2), allied to Hetteborm. 



SAXIFRAGACE^E. Gardner describes a shrub which he discovered on the 

 Organ mountains at Rio, as Raleighia (Lond. Journ. of Bot. 1845, p. 97), 

 with the following essential characters : Calyx four-partite, valvular, corolla 

 absent, stamens numerous and perigynous, ovary one-celled, with a single 

 style and 3 ( 2) placentae, supporting numerous ovules, which are sub- 

 sequently situated on the median line of the valves of the capsule ; seeds 

 with an axile embryo ; leaves opposite, connate at the base, and serrated. 

 The author refers it to the Bixacese, but Bentham rightly places it in the 

 Cunoniaceee near Belangera, as it forms a transition link from this to the 

 parietal families, by its truly parietal placentae, but differs from the latter 

 by their attachment. Planchon takes a different view of Raleighia 

 (ib. p. 476) ; from the examination of dried specimens, he regards this genus 

 as scarcely generally distinct from Abatia (Lythrarese, vid. Sup.), which 

 cannot be the case unless both Gardner and Bentham have described the 

 fruit and seeds totally incorrectly.
