NOTES ON LITTLE-KNOAVN TREES AND SHKUBS.

Lecin.minosce, this is probably not a long-lived plant ; we believe it, how- 

 ever, to be quite hardy near London. 



* Erinacea pungens. — Like the last this is a native of Spain. It was 

 cultivated by Philip Miller in 1759, and was figured in one of the 

 earlier volumes of the " Botanical Magazine." It is a dense, low-growing, 

 compact, spiny shrub with large blue flowers. There ought to be a clump 

 or two of this in the rockery, where it would not run the risk of being 

 removed or tampered with. It is a very beautiful shrub. The first time I 

 saw it in cultivation was in Canon Ellacombe's wonderful garden at Bifcton. 



Cytisus keioensis. — As implied by the name, this charming shrub 

 originated at Kew some years ago : it is a hybrid between the little 

 golden-yellow early-flowering C. Ardoini and the common white Spanish 

 Brcom, C. albus, the former being the seed parent. The flowers of 

 C. kacensis are a creamy white, and the plant is prostrate in habit : it makes 

 an excellent effect in the rockery. 



Ononis fruticosa. — A very old garden plant cultivated by Philip 

 Miller in 1748 : it should have a place in tbe rockery, where it is likely to 

 thrive better than in the shrubbery proper. 



0. aragonensis is a native of Northern Spain, and is an admirable 

 rockery shrub : it makes a compact bush laden with upright racemes of 

 yellow flowers. 



Bobinia neo-mexicana. — This is a comparatively new introduction : it is 

 the western representative of the eastern B. viscosa, a native of Carolina, 

 which Sargent in his " Silva of North America " states is one of the rarest 

 trees of the United States. B. neo-mexicana reaches the eastern slopes 

 of the Rocky Mountains, and is found at elevations of from 4,000 to 

 7,000 feet. It flowers in June and bears short dense racemes of pale 

 rose-pink flowers followed by pods thickly clothed with rigid bristles and 

 gland- tipped hairs. Very often, as is also the case with B. viscosa, a 

 second crop of flowers is produced in autumn. 



Notospartium Carmichaelice. — The pink Broom of the residents of 

 the Middle Island, New Zealand, is a shrub or small tree attaining a 

 height of 20 feet, with weeping cord-like leafless branches and short 

 racemes of bright pink-purple flowers. Like the majority of New 

 Zealand shrubs this is hardly to be depended on near London in the open 

 shrubbery, but does well against a wall. Further south ic would doubtless 

 succeed better. 



Caragana aurantiaca. — Amongst the dwarf deciduous Leguminosce 

 there are few more beautiful flowering shrubs than this. It is perfectly 

 hardy, grows almost under any conditions as to soil or situation, and bears 

 an abundance of its showy orange-yellow flowers. Probably a native of 

 Central Asia. 



Sophora viciifolia. — The contrast between the violet-blue calyx and 

 the cream-white corollas of this plant is very striking : it is a beautiful 

 little bush recently introduced from China. In a wild state it grows 

 from 2 feet to 4 feet high, and on the Tibet frontier occurs at eleva- 

 tions of from 9,000 feet to 13,500 feet above the level of the sea. 



Prunus subhirtella. — This beautiful Japanese shrub or small tree 

 was sent to Kew from the Arnold Arboretum some few years ago. In the 

 middle of March this year a specimen in the Kew collection was a sheet of
