Running water in El Valle de Uspallata, Andes of 
Mendoza, Dr. Gillies. Valparaiso, Cuming (N. 638.) ; 
Bridges, 1832, (N. 546.)— The floral leaves in all Dr. 
Gillies’ specimens are of a fine bluish-green. This 
is seemingly intermediate between the true M. ternatum 
and M: elatinoides, Gaud., with which last it agrees in 
the number of floral leaves, but differs by the monceci- 
ous flowers.

Lagunilla, near Mendoza, Dr. Gillies. Moist woods of

Cuming (N.125.) Juan Fernandez, Bertero; Douglas.— 
The plant found by D'Urville at Conception, referred

Buenos Ayres, Dr. Gillies; Tweedie.—Our plant cor- 
responds exactly with the description above referred 
to, except in the size of the dorsal calycine segments, in 
which respect it agrees with C. spicata; but that species

(2.) Cuphea spicata, Cav.—Uraguay, Tweedie. 
(3.) Cuphea glabra, (Gill. mst.); floribus endecandris 
oppositis pedunculatis ecalcaratis, dentibus calycinis 
sequalibus, stylo et germine supra villosis, ovulis 30-40, 
racemo brevi 4-6-floro, ramis extrafoliaceis, foliis an-
