Plantae novae andinae imprimis Weberbauerianae. I. 519 
Species circiter 60 Americae Australis: Ecuador, Peru, Bolivia, Argen- 
tina ad Cordillera de la Rioja et Chile ad Cordillera prope Santiago; in 
America australi tropica inter 3900 et 5000 m; in America australi tempe- 
rata supra 2500 m. 
The range of the genus appears to extend from the high mountains 
of Antisana, Pichincha ete. on the borders of Ecuador and Colombia, as far 
south as the cordillera of Santiago in Chile with an eastern extension 
through Bolivia into the Provinces of Salta and La Rioja (Sierra Famatina) 
in Argentina. 
The genus appears to reach its maximum development in the south 
of Peru and in Bolivia. 
The species are as a rule easily recognized and very much localized 
in their range, in some cases a species being confined apparently to a single 
mountain. 
The plants form lax or dense rosettes of radical leaves, or they may 
be shortly caulescent (e. g. N. Lobbii, N. auricoma); a few are annuals. In 
the case of the rosette forming species there is a distinct stem, on which 
the leaves are closely imbricated, and it gets pulled down into the ground 
or buried by blown dust or sand as the plant grows upwards. 
The following species placed by Gray and others under Malvastrum t) 
must now be referred to the genus Nototriche.

To these described species I have to add nineteen new species, eleven 
of these having been collected by Dr. WrBERBAUER, during his recent ex- 
pedition in Peru, 2 from Fıesrıs’s collection from Southern Bolivia, whilst 
the remaining six were collected in 1879 in Argentina by Drs. Hieronymus 
and NrEpEnLEIN and Lorentz. The descriptions of the new species and an 
emended one of N. aretioides now follow.
