From the above description it will be seen that the genus 
Himeranthus is very distinct from the Jaborosa of Jussieu, 
founded originally upon the plant discovered by Commerson, 
which is the only species known, and which has been very 
accurately described and figured by Sir Wm. Hooker, (Bot. 
Mag. tab, 3489), from living specimens raised in Glasgow, 
from seeds sent home by Mr. Tweedie.* 
2. Himeranthus erosus (n. sp.) ;—foliis subintegris, vel eroso- 
sinuatis, carnosulis, petiolatis, petiolo crasso suleato; pe- 
dunculo petiolo 3-plo-longiori ; corolle lobis integris, acu- 
tis—In Provincia Bonariensi. 
I found this plant at some considerable distance from Bue- 
nos Ayres; the leaves are more than double the length of 
the former species, comparatively broader, more entire, the 
petiole being about 2} in. long, very fleshy, semiterete, with 
slightly decurrent margins, The peduncles are from 4 to 6 in. 
long; the flowers are larger, the tube of the corolla not so 
much contracted in the mouth, and the segments of the bor- 
der larger in proportion; the filaments are nearly half the 
length of the tube of the corolla, are fixed about the middle 
* ] did not find any specimen of Jaborosa during my journey, but judg- 
ing from the excellent figure above mentioned and the dried specimens | 
have seen, I subjoin what I consider to be an amended character of this 
genus, 
Jasorosa, Juss.—Calye 5-fidus, Corolla hypogyna, tubo longissimo infun- 
dibuliformi, limbo plicato, 5-partito, laciniis longis, valde acuminatis 
Stamina 5, corolle fauci inserta, inclusa, sessilia, filamentis ad tubum 
corollz arcte concretis ; antheris dorso insertis, connectivo apiculatis, 
longitudinaliter dehiscentibus. Ovarium 2-loculare, placentis dissepi- 
mento insertis, multi-ovulatis. Stylus simplex longe exsertus. Stigmata 
5, longe linearia, erecta. Bacca calyce suffulta 2-locularis. Semina plu- - 
rima, subreniformia. Embryo ignotus. 
Herba Bonariensis subacaulis, prostrata, radicans ; foliis integerrimis, oblon 
gis, petiolatis ; pedunculis longis, solitariis, 1-floris, 
1. Jaborosa integrifolia, Juss. Lam. Dict. 3, 189, tab. 114. Hook. Bot, 
Misc. 1. 347. Bot. Mag. tab. 3489,—Bonaria. 
In order to exhibit more strikingly the difference between the two genera 
I have placed in juxta-position with Himeranthus erosus in Tab. v. 8B. 
Sir Wm. Hooker’s representation of Jaborosa integrifolia.
