BENEDICT: ANTROPHYUM 457 
The material of A. sadsessile so-called from Jamaica seems to 
belong here, but its form is not typical. It is much shorter and 
usually more oblanceolate and less acute, but it shows to a marked 
degree the line of dots along the ends of the veinlets. The range 
in size is shown by the following specimens : 
Underwood 1370. 21.5 xX 2.5 cm. 
Jenman, coll. in 1876. 18 x 3 cm. 
Species inguirenda 
AntRopuyum Desvauxit Moore, Ind. Fil. 80. 1858. 
Hemionitis gigantea Desv. Prodr. 216. 1827. (Type from St. 
Thomas, West Indies.) 
frondibus ecostatis, late lanceolatis, acutis, basi in stipitem late 
compressum dilatatis; lineolis dense reticulatis superficialibus. 
Ffabitat in insula Sancti-T) homae Antllarum. 2 ped. etultra; 4 
poll. lata. (Desvaux.) 
The description agrees with that of Bory’s Antrophyum gigan- 
teum, fromthe Mascarene Islands. The characters and dimensions 
given fit that species exactly. The following quotation from De 
Candolle’s “‘ Phytographie ” may throw some light on the confusion. 
Speaking of Desvaux’s herbarium, the writer says (page 408), 
“ Les omissions ou indications fausses de pays et la similitude de 
certains échantillons avec ceux du Muséum rendent cet herbier fort 
curteux.” As the species under consideration could not possibly 
have come from the locality cited, the conclusions are obvious. 
The only possible explanation creditable to Desvaux, is that his 
* material came from the African island, St. Thomas, which lies off 
the west coast, but this presupposes an improbable distribution 
for the fern, to say the least, and the accidental confusing of the 
two continents is not very likely. 
Species excludenda 
ANTROPHYUM MINIMUM Baker, Ann. Bot. 5:488. 1891. (Type 
from Costa Rica.) = Hecistopteris minima (Baker). 
Soon after I began to study this species, I came to the conclu- _ 
Sion that it belonged with Vittaria because of (1) the diplanate 
Spores and the peculiarly shaped paraphyses, which are identical 
in form and size with those of Vittaria costata Kunze, (2) the
