374 SHORT NOTES. 



in the eastern districts of the colony. It bleeds freely and 

 copiously. Another species found more to the eastward, and in 

 Natal, is E. quinata (a bad name, of no authority I fear). This is 

 the largest growing succulent Euphorbia I am acquainted with, 

 exceeding in height E. (jranoideus, and larger in circumference 

 than that species. A good specimen of E. quinata (?) is a hand- 

 some object, although of so singular aspect. The quantity of juice 

 yielded by this tree is very plentiful. From this and the preceding 

 species the sap was taken, I believe, for experiment." — J. R. Jackson. 



Barbarea 



This plant was 



gathered by Mr. A. D. Melvin and myself at Worcester, near the 

 river, in June last. I have since been informed that it was also 

 met with at Malvern some time since, but, I believe, lias never 

 been recorded as a Worcestershire plant. We saw a considerable 

 number of specimens in two meadows, so that it seems fairly 

 established. — R. F. Towndrow. 



Rare British Plants.— While on a botanical excursion in the 

 neighbourhood of Dover I was shown, in a garden under the cliff, 

 not far from Lydden Spout, a plant which was unknown to the 

 owner of the garden, who believed it to have sprung up from rail- 

 way ballast. The plant was Salvia clandestina, and not far from 

 it was a solitary specimen of Xanthium xpinomm. Frankenia 

 lavh also occurred sparingly below Shakespeare Cliff, while 

 Enteromorpha maryinata, Le Jolis, a form not before recorded as 

 British, I behove, was abundant on some muddy ooze by 

 the shore. By some means or other Teucrium Botn/s has 

 established itself by the roadside near Mill Hill, from whence I 

 have received a specimen gathered by M. C. Chantre this year. 

 It would be interesting to learn if it has been planted there by any 

 botanist. — E. M. Holmes.
