4—5-jugate, the lowermost pair anastomosing. In size, colour and venation it re- 
sembles very much JD. asplenioides, which, however, is indusiate and pinnate to 
short of the apex with most of the pinnz stalked; in our variety long simple hairs 
are few or none on rachis. and coste beneath, which are stellato-puberulous, in 
D. asplenioides long hairs as a rule are more numerous than the stellate ones.

‘‘Nephrodium subovatum Jenman, “Argosy”, Demerara”. (t. JENMAN). 
Type from Guadeloupe, leg. L’HERMINIER (Herb. Cosson, Paris! and authen- 
tical specimens in B and C). 
A most distinct and uniform species, excellently described by JENMAN and 
Maxon (loc. cit.). It resembles in size, colour and texture D. tetragona, from which 
it can be distinguished at once by the lamina being gradually narrowed upwards 
and by its venation. From the allied species without terminal pinne it differs by 
its most pinn: being distinctly stalked. The lamina is glabrous, the rachis and 
costz beneath excepted, which are puberulous by very minute forked or simple hairs. 
Lower pinne narrowed towards the base, generally not reflexed or abbreviated, 
upper ones with a truncate base, all scarcely incised one third to the costa. Lobes 
scarcely longer than broad, truncate and often emarginate at the apex. Veins 8—10- 
jugate the lower 3—4 much curved, connivent to sinus, or the lower pair occa- 
sionally united and sending a branch to the sinus; often the anterior basal vein 
ends in the leaf-tissue, not reaching the opposite posterior one. Sori medial, fur- 
nished with a small, ciliate indusium; head of sporangium glabrous, but its pedicel 
bears normally a stiff hair. — Rhizome obliquely erect or decumbent; stipe 40—60 
cm long, lamina 35 cm »« 20 cm ; pinnz 12 x 2!/» cm.  Rachis is sometimes gemmi- 
ferous in the upper part. 
D. latiuscula Maxon is exactly typical and N. subcuneatum Bak. is the same. 
The specimen from S. Domingo referred by Maxon to this species and to which the 
combination Dryopteris pyramidata first was applied, is not so typical, still scarcely 
different. It has the rachis and cost: beneath clothed with numerous long, whitish 
hairs, and its pinnz are incised about halfway to the costa. — D. pyramidata seems 
to be a rather common species in Guiana and the southern West-Indian islands. I 
have examined the following specimens:
