164 BENEDICT: GENERA OF THE FERN TRIBE VITTARIEAE 
Notice should be taken here of two other names recently pro- 
posed in Hecistopteris, viz., Hecistopteris Werckleana Christ (Bull. 
Herb. Boiss. II. 7: 265. 1907), and H. minima (Baker) Benedict 
(Bull. Torrey Club 34: 457. 1901907). The latter is the earlier 
species and was originally described by Baker as Antrophyum 
minimum and so appears in Christensen’s Index Filicum. Dr. 
Christ’s species Werckleana was also originally described as an 
Antrophyum, but was soon after shifted by him into Hecistopteris 
on account of the occasional forking of the tips of the leaves. 
This, however, is merely the abnormal forking frequent in all 
species of ferns. As it turns out, Antrophyum Werckleanum is 
identical with A. minimum Baker. This I have been able to de- 
termine through the kindness of Prince Roland Bonaparte, from 
whose herbarium a plant of the original collection of Werckleana 
has been obtained (PLATE 2, FIG. 4. Compare with FIG. 5 of the 
same plate, drawn from type material of H. minima). Both have 
the venation of Vittaria, and the species, which will need to be 
known under Baker’s name, should henceforth be called Vittaria 
minima (Baker) Benedict comb. nov. (PLATE 2, FIG. 4,5). Antro- 
pbhyum minimum Baker, Ann. Bot. 5: 448. 1891.

3. VITTARIA J. E. Smith, Mem. Acad. Turin. 5: 413. pl. o. 
; 1793 | 
Type species, Pieris lineata L. (Type specimen from Santo 
Domingo.) 
The genus Vittaria shows in its simplest species, V. sikkimensis 
Kuhn, a venation similar to that of Monogramma paradoxa. (Com- 
pare PLATE 3, FIG. 13, and PLATE 5, FIG. 18, 20, respectively.) 
It differs even in this species in having two separate sporangial 
grooves, and this character furnishes the most obvious generic 
mark. The venation consists always of a median vein with a row 
of areolae (I-many) along each side. This venation may be 
characterized as biseriate. .
