5. var. confinis (Maxon). 
Dryopteris ke inis Maxon in sched.; Aspidium pubescens var. glabrum Christ, Engl. 
Jahrb, 24: 117. 
A small, insular form with the lamina 20—40 cm long, basal pinnae 10—15 cm 
long only, scarcely more than 2-pinnate—3-pinnatifid, but otherwise not essentially 
different from var. divergens. The dull-green, nearly subcoriaceous lamina is some- 
times without hairs and glands beneath, still some specimens are pubescent as var. 
divergens, and others have rather many, sessile, shining glands spread over -the 
underside. 
The apex of the leaf is sometimes considerably elongated and bears a bud 
short below the tip. It is often confounded with D. cherophylloides.

Subgenus XI. Polystichopsis (J. Sm.) emend. C. Chr. 
Lastrea § Polystichopsis J. Smith, Hist. Fil. 217. 1875. 
A most natural subgenus or genus including several middle-sized species, that 
have a short- or long-creeping rhizome (rarely nearly erect as in D. denticulata) and 
an ovate or deltoid lamina, varying from bipinnate-tripinnatifid to 5-pinnate— 
6-pinnatifid, anadromous in all divisions (habit polystichoid) (fig. 2), rarely, 
as in the less divided forms, partly catadromous, often rigidly coriaceous, never 
gemmiferous. Scales of lamina in most species few or none, rhizome always but 
rather sparsely paleaceous. Several species perfectly without hairs, others with short 
or long paucicellular hairs. Sori indusiate: indusia of the first group small, of the 
second often large, coriaceous, rotundato-reniform, sometimes almost peltate; spo- 
rangia without gland on the pedicel; spores verrucose or papillose. 
This subgenus is, I think, more closely related to Polystichum than to Dryopteris ; 
it includes a number of Old-World’s species that now have been referred to the former, 
now to the latter, f. inst. Polystichum aristatum (Forst.) Pr. and P. hispidum (Sw.) J. Sm. ; 
also D. denticulata and D. amplissima have been considered species of Polystichum. All 
these species differ chiefly from true Polysticha by their creeping rhizome, much 
dissected leaf and in the rarely truly peltate indusia. More studies will show, I
