Neiio hardy Trees and SJiriihs raised at Chisvoick. 631 



We have heard little, during the year, of gardening improvements 

 going forward in Germany, except that a public garden has 

 been formed at Hamburg at the expense of the town, and for 

 the benefit of all the inhabitants. In Berlin, a new Botanical 

 Periodical has been commenced, of which a notice will be found 

 in p. BQ6. Great progress in gardening has been made in Rus- 

 sia, especially in the neighbourhood of Moscow (see p. 565.) ; 

 and ample accounts of the state of vegetable culture in Egypt 

 will be found in p. 645., and of North America in p. 642. 



Obituary. — The botanical and gardening worlds have lost in 

 the course of the year, Baron Jacquin, Allan Cunningham, and 

 Charles Sckell of Munich ; the last an eminent landscape- 

 gardener. 



Art. I. Report on the nexu Species and Varieties of hardy Trees 

 arid Shrubs raised in the Horticultural Society's Gardens since the 

 last Report, made in November, 1839, and published in the " Gar- 

 dener s Magazine" for 1840, p. 1. Drawn up for the " Gardener's 

 Magazine" by Mr. Gordon, of the Arboretum of the Horticul- 

 tural Society, by Permission of the Council of that Body. 



jBanuncula^ce^. — Mrdgene macropetala Ledebour's MS. This seems 

 a distinct species, and very little known, as I have not been able to find any 

 published account of it. It is, however, certainly a species of Jtragene, 

 and comes nearest to A. alpina, and, like that species, is quite hardy. I have 

 only succeeded in raising a single plant from a small paper of seed, presented 

 to the Society by Dr. Bunge of Dorpat. The plant is a native of Siberia, 

 and is said to have large white flowers, probably the Clematis sibirica flora 

 albo of the Hamburg collections. 



Berber£ce^. — Berberis (MahonM sp. Arb. Brit.} trifolidta Hartweg's 

 MS. This beautiful and very distinct species was raised from seeds received 

 from M. Hartweg, who found it growing at a place called San Luis Potosi, 

 in Mexico, covering large tracts of land, and almost the only flowering 

 shrub in that place, which was not eaten by the all-devouring goats. It is 

 very curious in having the leaves always in threes, and in showing the ap- 

 proach of the pinnate to the single-leaved species. It is probably about as 

 hardy as B. [M.] fascicularis, which its small yellowish green prickly leaves 

 resemble ; but the fruit is of a yellowish green colour when ripe. 



Berberis (Mahonza sp. Arb. Brit.} pallida Hartweg's MS. Benih. PlantcB. 

 Hartiu., p. 34. No. 268. This is another of the beautiful pinnate ber- 

 berries found in Mexico by Hartweg, who sent home to the Society a small 

 portion of the seeds, and from which a single plant only has been raised. 

 It resembles B. [M.] ^quifolinm ; but the leaflets are not so spiny, much 

 smaller, and from 11 to 15 in number. The flowers are of a whitish colour 

 (hence the name). The plant grows from 6 ft. to 8 ft. high, and was 

 found at a place called Tula, and also at Atotonilco el Grande, and San Jose 

 del Ora, near Zacualtipan in Mexico. 



Berberis (Mahonia sp. Arb. Brit.} gracilis Hartw. MS. Benth. PI. Hartw., 

 No. 271. This also is another very distinct species of Berberis, with not 

 more than 4 pairs of leaflets, but of the B. [M.] Jquifolium section, and but 

 slightly toothed. It was found by M. Hartweg growing about 6 ft. high, 

 at a place called Zimapan in Mexico ; and, like the preceding, he only found 

 a very small portion of ripe seeds, and from which only a single plant has 

 been raised in the garden.
