ities of Gardner’s collections in Brazil, Schomburgk’s in Guiana, Skin- 
ner’s in Guatemala, Linden’s in Mexico, Mr. Wright’s, &c. in the Falk- 
land Islands, and Cunningham’s, &c. in Australia. One of the most 
remarkable of Dr. Gardner’s plants is his Utricularia nelumbiifolia, 
(t. 505 ;) which sends up from a creeping stem numerous scapes more 
than two feet high, bearing a raceme of very lar ge violet-colored flow- 
ers, and round, centrally peltate leaves 3 or 4 inches in diameter, which 
resemble those of the Nelumbium! Among those from Mr. Skinner’s 
collection in Guatemala, we were surprised to meet with a Smilacina, 
(S. flewuosa, Hook.) The antarctic plants are especially interesting. 
Among them we have a figure (t. 492) of the Bolax glebaria of Com- 
merson, one of those dwarf and singularly tufted Umbelliferous plants 
so characteristic of the vegetation of the southern extremity of this 
continent. ‘The rounded and excessively dense tufts of this species, 
which in their young state D’Urville compares to mole-hills coy- 
ered with green turf, at length, according to Mr. Wright, resemble 
small haystacks! ‘Their appearance, we imagine, is not unlike that of 
the larger masses of Diapensia Lapponica upon the Alpine summits of 
the White Mountains, only that they are on a much greater scale. 
The Dalibarda geoides of Persoon and DeCandolle turns out a genu- 
ine Rubus. We find only two North American plants, viz. Carex fil- 
ifolia, Nutt., (under which a wrong name is inadvertently cited in place 
of that of the more able author of the Monograph of North American 
Cyperacez,) and Oakesia Conradii of Tuckerman. Sir Wm. Hooker 
has not the fruit of this interesting plant, and he states that the flowers 
in his specimens do not so well accord with Dr. Klotzsch’s description 
as could be wished. He figures the abortive pistil which is frequently 
found in the staminate flowers; but as he does not notice some curious 
particulars observed by the writer of this article, it may here be briefly 
mentioned,* 1. The plant is polygamo-diecious ; or, at least, some of 
the flowers are not unfrequently perfect. 2. These perfect flowers are 
sometimes provided with three stamens, similar to those of the sterile 
flowers; but more commonly they present a single antheriferous sta- 
men, sometimes accompanied by two short sterile filaments, and some- 
times destitute of these rudiments: occasionally a fertile flower is fur- 
nished with three short rudimentary filaments. 93. In the perfect flow- 
ers, especially when only one stamen is antheriferous, the anther is 
commonly found to be one-celled; the other cell being entirely sup- 
pressed, or else reduced to a mere vestige, as was seen in a single in- 
stance. 4. The lobes of the style are variable in number, and are of- 
* Since this article was in type, these characters have also been pointed out to 
the writer by Mr. Oakes, who furnished the specimens he examined,
