tree contain an active principle allied to the cathartine found in leaves 

 of Senna, and it is said that the wood cannot be worked for this reason 

 when fresh. There is a well under a tree in the Botanic Garden at 

 Dijon which is covered up at certain seasons in order that the water 

 may not be made medicinal by the flowers and leaves that would 

 otherwise fall into it. The pods are used in native medicine. The 

 old Botanic Garden was established in 1761 ; in Nicholson's 

 Dictionary the date of introduction is given as 1763 ; but Don, in his 

 Hortns Cantabrigiensis, gives 1753. This tree, however, is probably 

 younger than the 153 years possible on the site. The trunk of this tree 

 is very fine and symmetrical. 



12. Berberis Fremonti Torr., in Bot. Mex. Boundary, N.W. 

 America (Texas, Arizona, &c). 



This is a remarkably distinct Berberis. It is of shrubby, spreading 

 habit, with glaucous, pinnate leaves. The subject of this note is 8 ft. 

 high and 8 ft. wide, growing against the east side of one of the plant- 

 houses, where it is sheltered from the east and from the north. From 

 all information given me it must be the finest specimen in this country. 

 It has never flowered. In summer it is quite remarkable from the 

 glaucous blue tint of the leaves. Another glaucous-leaved Barberry, 

 native of New Mexico, is B. trifoliata, but the leaves are trifoliolate and 

 not pinnate. 



13. Rosa macrophylla Lindl. (Ros. Mon. p. 35, t. 6). 



This is a very fine Rose, native of the Himalayas and China, nearly 

 always in flower, and the largest, not a climber, in the Cambridge 

 Botanic Garden. It belongs to Lindley's Division, the Cinnamomeae, 

 and is well marked by its spineless character and very long, narrow 

 sepals, which are longer than the petals. The present tree in 1910 

 was 16 ft. 9 in. high and 24 ft. 2 in. through. It is now i8| ft. high 

 and 25J ft. through. The leaves are described as very long and are 

 so figured, but this is not always a feature of the living plant. It is 

 included here on account of its being 10 ft. in excess of the height 

 given for this Rose. 



14. Rosa moschata Herrm. Diss. 15. (Fig. 7.) 



R. Brunonii Lindl. (Ros. Mon. 120, 1. 14 ; Bot. Mag. t. 4030). 

 For many years this has been a feature in the Cambridge Botanic 

 Garden, climbing to the top of a Finns austriaca, and attaining 48 ft. 

 in height, with a diameter of 38 ft. Flowering in June, it is most lovely ; 

 the flowers are pure white and extraordinarily profuse. It is one of 

 the finest of climbing Roses, but makes a very good shrub in a large 

 bed. It is a native of Europe and extends to India. 



15. Xanthoceras sorbifolia Bunge (Bot. Mag. t. 6923). 



In the Botanical Magazine this is described as " one of the most 

 attractive and interesting hardy garden shrubs that has been intro- 

 duced for many years." The figure is a fine one and was chiefly
