tionum ramis diffusis, alternis fere semper abbreviatis, longe 
pedicellati, pedicellis eapillaribus dense pubescentibus: bractee 
parv: folia zquantes. Sepala ovato-lanceolata, dorso carinata, 
carina viridi dense pilosa, ceterum membranacea ac glabrescentia, 
Petala alba oblonga acuta, calyce triente breviora. 
Syn, A. diffuse, Elliott, affinis, fortassis species nova, ap. Peyritsch, 
in Linnea, xxx. p. 58. l 
Species A. megalanthæ atque A. pleuranthe valde affinis, 
tamen inflorescentia distinctissima primo aspectu diversa est. 
Etiam ad speciem sequentem accedit, quæ habitu, calycis struc- 
turá, petalis obtusis et caulis pubescentiá distingui potest. 
The species is found in marshy localities, under similar 
circumstances as A. palustris. 
Hab. Mexico: Real del Monte and Cerro Ventoso, also at 
San Miguel near Toluea at 2770 metres.

Caules humifusi longe repentes quadrangulares, ramos pluri- 
mos breves dense foliosos steriles, paucos elongatos minusque 
dense foliatos, apice floriferos, laxeque adscendenti-erectos, 5-20 
centim., edentes, eque ac ramuli pilis brevibus simplicibus stella-
