2. Himeranthus erosus (n. sp.) ;—foliis subintegris, vel eroso- 
sinuatis, carnosulis, petiolatis, petiolo crasso sulcato; 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 23 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- 
derlarger in proportion; the filaments are nearly half the 
length of the tube of the corolla, are fixed about the middle 
above the villous lines described in the last species; the style 
is hollow at the apex for one-sixth of its length, and the stig- 
ma, with three expanded, obtuse, and almost obsolete lobes, 
is exserted. Specimens of this plant existin Sir William 
Hooker's herbarium, gathered by Dr. Gillies.* 
3. Himeranthus ¢ridentatus (n. sp.) ;—foliis ovatis, angulato- 
have seen, I subjoin what I consider to be an amended character of this 
genus,

dibuliformi, limbo plicato, 5-partito, laciniis longis, valde acuminatis 
Stamina 5, corollze fauci inserta, inclusa, sessilia, filamentis ad tubum 
corolle 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- -

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 plate 5 of the 
“ Illustration of South American Plants," Sir Wm. Hooker's representa- 
tion of Jaborosa integrifolia. |
