 Jiuxburi/h ; on the trunks ol trees. — Assuredly a very protean species, and 

 widely extended in the tropics of the Old and of the \ew World. So vari- 

 able are the pinnules in different specimens and even on the same plant, 

 that it is next to impossible to form a specific character which shall dis- 

 tinguish them. The figure of Dryander does not represeiit the more usual 

 form, though the superior pinnules not unfiequently assume that character. 

 The larger specimens with the more falcate pinnules are the most abun- 

 dant and the most widely extended both in the East and West Indies. 

 Where the one is found, however, the other is generally found also. Mr. 

 Griffiths remarks of his recent specimens, that in certain lights they ex- 

 hibit a metallic blue tinge ; and this is singidarly the case with a Li/cupo- 

 dium (Sect. Slaclajgynandrum), now cultivated in the stoves of our botanic 

 gardens. The Liiulscm f'alcata of Dryander is simply a young, less divided 

 state of L. trapczifonnif. 



38, L. arcuata, Kze. ; " frond bipinnate, piuna3 (3 — 7) alter- 

 nate linear-oblong acuminate, pinnules dimidiato-ovate fal- 

 cate, lowest and ultimate ones flabelliforra, all incurved at 

 the obtuse apex, sori continuous on the superior margin."

39. L. caudata, Hook. ; stipes terete and as well as the 

 rachis deep brown glossy, frond bipinnate, pinna? narrow 

 numerous (11 — 17) lanceolate the apex long attenuate cau- 

 date, pinnules half ovate limulato-falcale decurved membrana- 

 ceous close, superior base truncate upper margin forming al- 

 most the segment of a circle quite entire, terminal ones gra- 

 dually smaller on the caudex or tail-like point, sori at the 

 very margin and continuous to the obtuse apex, 



Ilab. Adam's Peak, Ceylon, 3Irs. d'en. Ifalkcr. — I was at first disposed 

 to refer this to a slate of L trapeziformis, but the more numerous pinnas, 

 tapering to a tail-like point, blunter pinnules, exactly marginal sori, terete 

 and darker coloured sti])es, seem to indicate a specific distinction ; and 

 these characters exist in four fine specimens sent at difierent periods. I am 

 not disposed at all times to lay much stress on the 4-sided or terete stipes, 

 which difteiences are, sometimes at least, caused by the greater or less state
