3. D. sancta (L.) O. Ktze.; Mon. I. nr. 56. — In Sto. egy this species varies 
considerably. I have cuted the following varieties: 
typica C. Chr. Smiths. Mise. Coll. 52: 379, including the var. strigosa C. Chr. 
and var. hirta Jenm. C. Chr. |. ¢., which differ only by the more or less pubes- 
cent leaves, while the typical form is quite glabrous. — EGGers nr. 2512 b, 
2512, Picarpa nr. 312, 1180, 606, 685, 727 (B). 
var. Balbisii (Spr.) C. Chr. Vid. Selsk. Skr. VII. 4: 296 f. 20. This very charac- 
teristic variety, which was ofiginally described: by SpRENGEL after specimens 
from Porto Rico, BERTERO nr. 796 (B!) and erroneously by Kunn identified 
with D. Sprengelii, is not rare in Sto. Domingo: Eacers nr. 2540, 2540 b, 2780, 
WEINLAND nr. 56, J. N. Rose nr. 4386 (B). Underside of lamina glandulose, glabrous 
or slightly strigose on the ribs. Sori apparently exindusiate. 
. 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; indusia subpersistent, ciliate and with a few 
glands. — Fuertes nr. 1085 (B 
. var. ferminalis (Kuhn) C. Chr., Fedde Repert. 15: 26. 1917 (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 pinne below, the lower- 
most pair of pinnze being not much shorter than the following ones. Rachis, 
coste and costule beneath very short hairy, surfaces otherwise glabrous and eglan- 
dulose. Veins in larger pinnule about 8-jugate, often forked, remarkably thick, 
bearing the exindusiate sori near their apex in the teeth of the segment or pin- 
nule, nearly exactly as shown in my figure of var. Balbisii. In this respect it re- 
sembles D. limbata, to which species Kunn wrongly referred it. — It is not 
improbably a distinct species. 
Sto. Domingo, in sylvis montis Isabel de la torre, Eccers nr. 2775 (B). 
6. D. consanguinea (Fée) C. Chr. — Also Porto Rico, SinTENIS nr. 1753 (B). - + 
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 
can be safely distinguished from D. sancta. The pinne and segments figured by me 
belong, I now believe, to a small form of D. limbata. 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 consanguinea. This form 
is as to important characters, size, glandular underside, unequal-sided pinnz, scar- 
cely distinguishable from the typical D. sancta, and it is by nearly all authors refer- 
red to that species. Still it differs materially by its distinct, persistent glabrous or 
tet ciliated indusia, and further it differs by the shape of the segments, which
