(Tweedie, n. 448, in Herb. Kew., the type-specimens).—Argentina : 
open places near Bubiiis Aires, “along the Rio de la Plata (Tweedie, 
1837, in Herb. Hew.). The original specimens were collected by 
Tweedie in 1838, and sent to Hooker. In the following year the 
plant was described in the first volume of the new botanical journal, 
founded by Hooker, as a species of Erythrea. The leaves on the 
stem vary “thtek eight to eleven pairs, according to its length. The 
top Sd 24 mm. below the flower, are indistinguishable from bracts. 
Paragu As far as can be ascertained from the specimens 
available, they do not seem to rise much above the shore-level. 
n the fine collection of the plants of michael Spreneiys over 
avers! years, made by M. Emile Hassler, a w being worked 
out under the supervision of Prof. Chodat, the Swiss Botantat states 
that on account of the slight differences in elevation of the various 
districts visited, heights are not given on the labels attached to 
specimens. The same i so in the case of other collectors in 1 the 
plains of Eastern South Am 
The genus is Histitiniichied! Solis Erythrea and Sabbatia in the 
connivent lobes of the stigma, and also from the latter by the long 
corolla-tube.
