Memoranda of certain plants collected at Hurstperpoint in Sussex. 

 By William Mitten, Esq. 



Myosotis stiicta. — A plant possessing several characters in ac- 

 cordance with the descriptions of Myosotis stricta, Link, occurs in 

 several places. It was first observed on a sandy bank in company 

 with M. versicolor and M. collina, from both which it may be rea- 

 dily distinguished by its flowers commencing at the base of the stem, 

 below several of the leaves, and the calyx not spreading as in collina ; 

 the flowers are paler and rather smaller ; in M. collina the flowers 

 appear perfect when erect, while in my plant they are fully blown 

 on the curled portion of the raceme, and by the time they arrive in 

 the erect position are withered. I have not been able to detect the 

 hooked hairs in the living plant, but when dry they are curved in 

 various directions. I have observed this plant for some time, and 

 find no forms approaching either M. versicolor or M. collina. I 

 shall be happy to submit my specimens to a comparison with conti- 

 nental specimens of Myosotis stricta. Link. 



Cinclidotus riparius, Arnott, var. /3. terrestris, acrocarpous, peri- 

 stome and leaves exactly corresponding in structure with those of C. 

 fontinaloides, on stumps of trees in a rivulet. 



Phascum alterni folium, Bruch et Schimper, in many places. 



Tortula latifolia, Bruch, on posts and about the roots of trees ; sub- 

 ject at times to inundation, but always exposed to the light. 



Tortula squarrosa, De Notaris, on the downs, near : associated with 

 Didymodon flexicaulis. Wm, Mitten.

Occurrence of Alyssum calycinum near Epping. 

 By Edward Newman. 



Mr. Henry Doubleday informs me that Alyssum calycinum, a 

 plant well known as a native of Europe, has been found several times 

 by Mr. John Ray in the vicinity of Epping. It occurs in corn-fields, 

 and Mr. Doubleday considers that, in all probability, it has been in- 

 troduced, like many other plants, in foreign seed.
