178 SHORT NOTES. 



Wirtgeu's 7/. atro-ruhms and Miiller's Ii, adornatua will be found in 

 the 'Herb. Ruborum.' Bloxam's R. atro-ruhens agrees well with 

 the specimens issued by Wirtgen, except that its panicle is much 

 more setose and aciculate ; but this is only a difference in the 

 proportional abundance of those arms. It differs from our 

 hi. folumis chiefly by its terminal leaflet bemg much less cordate 

 and narrower at the base. Indeed one of the specimens from 

 Bloxam is scarcely at all cordate and decidedly narrowed to that 

 part. To this specimen Bloxam appended a (?) in 1869. But it 

 seems quite connected with the others by intermediate forms. 



If B. adornatus (B. atro-ruhens, Blox.), is to be distinguished 

 from our B. foUusus, it may be known by its terminal leaflet not 

 being roundly cordate-acuminate, but rather broadly obovate- 

 acuminate. But, in my opinion, we must place B. adornatus as the 

 name of the species and B. exsecatus (B. folumis, Blox.), as a 

 form of it.

SHORT NOTES. 



Caltha radicans, Forst. — It is much to be wished that some 

 botanist would visit the station given for this plant by Mr. G. Don, 

 to see if it can be again found. The place ought not to be difficult 

 to find, and a few hours' search give a valuable result. The 

 locality is thus stated by Don : " I found this [C. radicans'] about 

 the year 1790, in a ditch that runs from the farmhouse called 

 Haltoun, on the estate of Charles Gray, Esq., of Carse." — G. Don, 

 in Headrick's ' Agriculture of Forfarshire,' Appendix, p. 25. — 

 C. C. BabinctTON. 



DioN.^EA. — In noticing Fraustadt's paper on Dionata, in Cohn's 

 " Beitrage " (' Journ. Bot.,' 1877, p. 213), I stated that this author 

 differed from M. DeCandolle in not finding a large cell at each side 

 of the articulation at the base of the sensitive bristles. M. 

 DeCandolle has been good enough to give me a preparation 

 sliowmg one of these ' cells of tlie articulation ' in a very clear 

 manner. — S. Mooee. 



Centaurea Jacea, Linn., in Sussex. — The Bev. E.N. Bloomfield 

 has sent me a specimen of typical C. J area, gathered in a meadow 

 near Guestling Rectory, about the year 1805. He also niforms me 

 that he found some more s])ecimens in another meadow, in 1870, 

 which he sent to Mr. Roper. I excluded it from my list because I 

 thought it probable that the specimens collected by the late Mr. 

 Borrer actually escaped from his own garden. It would appear, 

 however, that this species may be really indigenous in the county. 

 — W. B. Hemsley.
