2536 (7*). Lygodium graeile, n. sp. — Stem very slender, 

 sarrnentose, glabrous. Sterile pinnre long-petioled, deltoid, tri- 

 pinnate, glabrous, moderately firm in texture; lower pinnules 

 deltoid, with compound lower tertiary segments; ultimate segments 

 lanceolate, f-1 in. long, £ in. broad. Veins lax, distinct, forked, 

 erecto-patent. Ultimate fertile segments deeply pinnatifid ; spikes 

 of fruit placed at end of the lobes, not above l-12th in. long. — Most 

 resembles L. mierophyllum E. Br.

So far, therefore, it would seem that the ferns of St. Domingo 

 correspond closely with those of Jamaica. Here, as in Jamaica, 

 we obtain characteristically temperate types (e. g. Nephr odium Frfix- 

 wcis and Lycopodium clavatum) on the high mountains. Besides the 

 three novelties, this collection adds to the West Indian flora PeUma 

 ternifolia* and Lycopodium subulatum, two widely spread Mexicano- 



Andine species. 



ON NOMENCLATIVE. 



By W. H. Beeby, A.L.S. 



In Mr. B. D. Jackson's concluding paper on the ' Nomenclature 

 of the London Catalogue ' (Journ. Bot. 1887, p. 334), he proposes 

 an alteration in the statement of the name " Sparganiiun ramomm 

 Curtis "; and in the same number of this Journal (p. 3-19), 

 Mr. Druce asks, — " Why write Sparganium ramomm Curtis, why 

 S. ajfine Schniz. ?" Neither of these gentlemen has brought forward 

 any evidence to show T that S. raniosum Hudson can be regarded sa 

 other than an aggregate name [Of. Joum. Bot. 1885, p. 193, and 

 !836, p. 142) ; and if Mr. Jackson's proposition (which consists of 

 the citation of Hudson's name with the supplementary quotation of a 

 plate) be accepted, we must also concede to South European 

 botanists the right to continue to apply Hudson's name to their 

 °. neglectum ; for there is not one word in Hudson's description 

 ^bieh is not equally applicable to both plants, nor is there any- 

 tjiing in their distribution to give a clue to either plant as being 

 the one intended by him. As the above proposals have a some- 

 what wide bearing on the subject of nomenclature, I may perhaps 

 be permitted to make a few observations. Although heartily in 

 accord ^ith the movement, of late so active in this country, to 

 ascertain what are really the names of our plants, I think that 

 something more is required than the hunting-tip of the oldest 

 name ever applied, but sometimes applicable only in the m- t 



&nce this was written PelUea ternifoUa has also been receh I from Jamaica.
