OF UTRICULARIA FROM SOUTH AMERICA. 175 
No. 2967. “ Locis arenosis fl. Negro inundatis.” San Carlos. 
I refer this plant, though with some hesitation, to U. cornuta, 
Mx. of which I take it to be a small variety. In the same 
species may probably be merged U. colorata, Bj., and U. appressa, 
St. Hil. Style, at flowering, about equalling the ovary. Pedicels 
slender, erecto-patent, not shorter than the calyx. Spruce de- 
scribes the leaves as ligulate, retuse, l-nerved, with a few sacs 
underneath. Flowers yellow, with a red arc on the palate. 
No. 1256. Barra? 
No. 2257. San Gabriel. 
No. 3644. Flum. Maypures. 
These approach U. subulata, L., very. closely. І cannot distin- 
guish them from that species. U. nervosa, G. Web. MS. in Hb. 
Berol. (Benj. Monog. Utric. Bras. p. 247), seems to me doubtfully 
distinct from the same, and to this form probably Spruce's plants 
may be referred. 
No. 3037. San Carlos. In bad condition; perhaps the same with the 
foregoing. 
No. 924. Santarem. Likewise imperfect : apparently of the same diffi- 
eult group with the last four numbers. 
In the * Linnea,’ vol. xx. p. 319, Benjamin describes, under the 
name of Akentra, a supposed new genus of Lentibulariee, founded 
upon a plant of Hostmann’s (Surinam Coll. No. 85), to but insuf- 
ficient examples of which he had access. He appends to his 
description the following honest observation, which, however, can 
scarcely be said to establish the propriety of publishing the genus 
under such circumstances :—“ Der Mangel des Sporns (weshalb 
ich den Namen Akentra (xévrpov, calcar) wählte) schien mir ап 
mehreren Exemplaren, die ich sah, deutlich zu sein, doch waren 
die Blüthen durch das Trocknen so unkenntlich geworden, dass 
ich nicht ganz sicher bin, ob nicht vielleicht, was ich als Unter- 
lippe beschrieb, der Sporn sei; künftige bessere Exemplare 
werden das entscheiden und vielleicht eine Aenderung des 
Namens nóthig machen." An examination of the specimens 
in the Kew Herbarium, collected by Hostmann, confirms the sup- 
position here expressed, that the remarkably large, saecste, 
oblongo-cylindrical, and abruptly obtuse spur has been mistaken 
for the lower lip of the corolla, and that the plant'is-a true 
Utricularia. From the extreme delicacy of the — have not
