however, strongly suggested N. pringlei, and subsequent comparison of a speci- 
men of the type collection of P. greggii with N. pringleit has shown them to be 
identical in every respect. The specimen referred to, Gregg 467, is no. 47866 in 
the Herbarium of the Missouri Botanical Garden and has the following data: 
“Allosorus Greggii n. sp. 467. Rock-fern, Rocky hill n. west of Mapimf, 
N. Mexico. Dr. J. Gregg. April 17, 1847.” The name is in Mettenius’s hand- 
writing. Mapimf is situated in the northern part of the State of Durango, 
northwest of Lerdo and Torreén. The displacement of the well-known name, 
N. pringlei, given first to Pringle’s excellent material, is unfortunate. It is, 
however, important to place beyond doubt the older species of Mettenius, which 
apparently has had only nominal recognition, and that under the wrong genus, 
The following specimens of WN. greggii are in the National Herbarium: 
Duranco: El Mundo Hill, near Lerdo, alt. 1,650 meters, Chaffey 58 in 
small part. 
CHIHUAHUA: Dry calcareous ledges and bluffs, Santa Eulalia Mountains, 
April 23, 1885, Pringle 441 (4 sheets), the type collection of N. 
pringlei. 
CoaHUILA: Sierra Mojada, Jones 519. San Lorenzo de Laguna and vicin- 
ity, 22 to 27 leagues southwest of Parris, May 1 to 10, 1880, Palmer 
1882 (2 sheets) ; Palmer 1383 (2 sheets). Mountains 24 miles north- 
west by north from Monclova, September 1 to 6, 1880, Palmer 1384 
(2 sheets). 
MISCELLANEOUS NOTES. 
Bommeria ehrenbergiana (Klotzsch) Fourn. 
An additional collection of this rare species has been received: 
Mexico: Pont de México, near Puebla, December 20, 1908, Arséne. 
Coniogramme americana Maxon, nom. nov. 
Gymnogramme subcordata Eaton & Davenp. Contr. U. S: Nat. Herb. 5: 138,

Coniogramme subcordata Maxon, Contr. U. S. Nat. Herb. 17: 174. 1913, not

In transferring recently to Coniogramme the Mexican plant described orig- 
inally as Gymnogramme subcordata the writer overlooked the fact that the 
name Coniogramme subcordata had already been formed by Copeland for a 
Philippine plant. The Mexican plant is therefore renamed as above. It is the 
only American member of the genus Coniogramme. 
Danaea crispa Endres.

additional specimen is received: 
Costa Rica: Sur les vieux troncs d’arbres aux collines supérieures de 
Santiago prés San Ramon, Brénes 14419.
