3. var. portoricensis (Kuhn) C..Chr. Smiths, Misc. Coll. 52, 380. — 
Like var. Balbisii, but rather hairy throughout, especially on rachis, ribs 
and upperside, scarcely glandular beneath. Sori indusiate; indusium 
subpersistent, ciliate, and with a few glands. 
M. Fuertes no. 1085. 
4. var. terminalis (Kuhn) C. Chr. nov. var. — (Aspidium terminale Kuhn, 
in sched.. In general habit, texture and cutting fully like var. Balbisii, 
but still larger, nearly tripinnatifid, differing from the two former varieties 
by its non-attenuate lamina, i. e.it lacks the dwindling pinnae below, the 
lowermost pair of pinnae being not much shorter than the following ones. 
Rachis, costae and costulae beneath very short-hairy, surfaces otherwise 
glabrous and eglandulose. Veins in larger pinnules about 8-jugate, often 
forked, remarkably thick, bearing the exindusiate sori near the apex in 
the teeth of the segment (or pinnulae), nearly exactly as shown in my 
figure of v. Balbisü (ei In this respect it resembles somewhat D. 
limbata (Sw.) O. Ktze., to which species Kuhn unrightly referred it. — 
Stipe 15 cm, lamina 35 cm long, largest pinnae 7 cm long by 2 cm broad. 
May be a distinct species. 
Eggers no. 2715. 
Obs. The presence of a distinct indusium in D. sancta var. portoricensis 
makes it doubtful whether the form from the Lesser Antilles referred by 
me to D. consanguinea (Feé) C. Chr. (Vid. Selsk. Skr. VII, 4, 297) can be 
safely distinguished as a species from D. sancta. I have some doubt 
what the true Aspidium consanguineum may be. The pinnae arid segments 
figured by me (l. c. fig. 21) is nearly certainly a small form of D. lim- 
bata (Sw.) O. Ktze. But there occurs in some of the islands, especially 
Martinique, Dominica: and Guadeloupe, and also Porto Rico 
(Sintenis-1753) a smaller form, which perhaps is the true D. consan- 
guinea. This form is as to important characters, size, glandular under- 
side, unequal-sided pinnae, scarcely to distinguish from the typical D. 
sancta, and it is by nearly all authors referred to that species. Still it 
differs materially by its distinct, persistent glabrous or slightly 'ciliated 
indusia, and further it differs by the shape of the segments, which are 
attenuated towards the apex, sometimes nearly triangular, not as those 
of D. sancta linear. Thus it recedes from D. sancta in the direction of 
D. opposita.
