Field Notes. 



which is taken up in the new ed. of Babing-ton, will not be 

 familiar to British botanists generally. It was published in 

 Sobolewski's 'Flora Petropolitana,' etc., 1799. As the name is 

 taken up by Ruprecht (1845), ^'^'^ '^^"^^ ^7 Ledebour, Fl. Rossica, 

 iv., p. 465, 1853 (though he refers to Ruprecht), it is probably 

 correct ; and as Smith's was not published (English Botany, 

 t. 1467, ist June 1805) till 1805, Sobolewski's name takes pre- 

 cedence. Richter, PI. Europ., i., p. 38, 1890, makes it a var. of 

 geniculatus, but this had previously been done by Weinman 

 ('Flora Petropolitano,' p. 10) in 1837. — A. Bennett. 



Ostnunda regalis at Qoathiand. — I do not remember 

 seeing in the programme of the Y.N.U. excursions to Goathland, 

 any mention of the above-named fern as growing there. If it 

 has been overlooked, I should like to place it on record that in 

 former years it was very common in a little copse at Darnholm, 

 adjoining Mr. Matthew Leng's pasture and garden. Before the 

 railway was removed to its present route, and when the carriages 

 were drawn up the old incline by a rope attached to a standing 

 engine at the top of the hill, the engine-driver always had three 

 or four plants of this fern in pots in his engine-room. He began 

 selling them, and practically cleared the plant out of the district. 

 Mr. Leng, seeing this wholesale destruction, took up the few 

 ferns that remained and planted them on his side of the hedge 

 with some large clumps that were already there. I believe these 

 still remain. — Jno. Braim, Pickering.

MOSSES AND HEPATICS. 

 Tortuia Isevipiliformis DeNot. — A New Observation. — 



This moss, growing on trees near Lewes, Sussex, and related 

 to T. Icevipila, was kindly sent to me by Mr. W. E. Nicholson. 

 On examining it under the microscope, I observed young plants 

 formed in situ in the middle of the rosette of brood-leaves. 

 This fact is not mentioned by Correns, who has carefully 

 examined and described the structure of this moss. Correns 

 g-rew the ' brood-leaves ' in nutrient fluid, and found that they 

 produced protonemal threads, on which young moss-plants then 

 arose. This, however, took place only after the brood-leaves 

 had become free and detached from the plant. Correns says 

 these leaves become broken off at their bases, where there is a 

 zone of thin-walled cells. — Wm. Ingham, 15th October 1904.
