Underwood, L. M., The names of some of our native ferns. 
(Torreya. VII. p. 193—198. October, 1907.) 
The writer calls attention to several changes in the nomen- 
clature of North American ferns as brought out by Christensen 
in his recent Index Filicum. Most of these are held to be warranted. 
The writer notes also the varying usage, at different botanical 
centers, in the generic name applied to the Polypodium filix-mas of 
Linnaeus. Though properly, known as a Dryopteris, it is neverthe- 
less listed at present under no less than 4 additional generic names, 
viz.: Polystichum, Lastrea, Nephrodium and Aspidium, this in spite 
of the so called “Vienna rules” of recent date. 
American specimens usually listed as Ceratopteris thalictroides 
(L.) Brongn. are held to constitute a distinct species, C. pteroides 
(Hook.) Underwood, quite distinct from the Old World form in 
several essential characters. Maxon.

Description of Lindsaea Pittieri Underw. & Maxon, founded on 
specimens collected by H. Pittier (n°. 533) near Cördoba (altitude 
30 to 100 meters) in the Dagua Valley, Pacific Coastal zone, State 
of Cauca, Colombia; probably nearest related to L. Leprieurii 
Hook., which has been erroneously merged with L. falcata. 
Description of L. cubensis Underw. & Maxon, founded on 
Wright’s n°. 3947 from Cuba. Various recent collections from Cuba 
are the same. A delicate species with slender stramineous vascular 
parts, in this respect somewhat suggesting the East Indian L. 
cultrata. The difform fronds are characteristic. Maxon.

africaines de la tribu des Sarcanthees, d’apres les collec¬ 
tions du Museum de Paris. (Bull. Soc. bot. France. Memoire. 9. 
65 pp. 12 pl. 1907.) 
La forme du rostellum et de la bandelette fournit des caracteres 
constants et precis, qui ont permis ä l’auteur de delimiter des genres 
bien definis et d’apporter un peu d’ordre dans les Sarcanthees afri¬ 
caines. En particulier il a fallu creer des genres nouveaux pour un 
grand nombre d’especes de-Situation douteuse, mises par Bentham 
dans le genre Angraecum.
