the filaments: the first grounded solely upon the adop- 

 tion of an error originating with Mr. Nnttall, who had 

 overlooked the glands ; the other . aot constant in the 

 genus, as proved by the samples of MaHonia nepalensis in 

 the Lambertian Herbarium, where the filaments are simple. 

 In respect to the difference of habit arising from the une- 

 qually pinnated foliage of the group proposed for Mahonia, 

 it has been as acutely as judiciously remarked to us by Mr. 

 Brown, that the footstalk of the simple leaf of all Berhe- 

 rides is jointed, a modification known in many cases, par- 

 ticularly in Jasminecey to be a natural step in the pro- 

 gressive transition from the simple to the pinnated or com- 

 pound state of foliation. In Berbbris tragacantkoides and 

 caragancefolia, although the leaf consists of one or two 

 pair of leaflets without the odd one at the end, the place 

 of that odd one is nevertheless supplied by a trifid spine. 

 The germen is certainly one-celled and not three-celled, as 

 asserted by Pursh, The result of the review of these as- 

 sumed distinctions proving such, we cannot but feel with 

 Mr. Brown that they afford no pretence for following out 

 the separation of Mahonia from BfiRBEitis, and we have 

 consequently considered them of the same genus. 



The introduction of this highly oi'uamental shrub is due 

 to Mr. Lambert, who raised it from seed sent to him by 

 Professor Lagasca from the Botanic Garden at Madrid, 

 where it had been obtained from seed collected at Monterey, 

 on the coast of California, by Don Louis N^, the natu- 

 ralist of the expedition under the command of the ill-fated 

 Malespina. The species has been also observed by Messrs. 

 Hnmboldt and Bonpland near Moran, in Mexico, at the 

 height of 1340 fathom above the level of the sea. 



Two plants of the shrub are now (March) covered 

 with their golden fragrant blossom in the greenhouse at 

 Boyton, where they have attained the height of five or six 

 feet. Don MSS.
