OF rTETCULARIA FROM SOUTH AMERICA. 175 



No. 2967. " Locis arenosis fl. Negro inundatis." San Carlos. 



I refer this plant, tliougli with some hesitation, to TI. cornuta, 

 Mx., of which I take it to be a small variety. In the same 

 species may probably be merged TI. colorata, Bj., and JJ. 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, 1-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. I 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- 

 cult group with the last four numbers. 



tn the ' Linnaea,' vol. xx, p. 319, Benjamin describes, under the 

 name oiAkentra, a supposed new genus o^ LentihulariecejioundieA. 

 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 (Kevrpov, calcar) wahlte) schien mir an 

 mehreren Exemplaren, die ich sah, deutlich zu sein, doch waren 

 die Bliithen durch das Trocknen so unkenntlich geworden, dass 

 ich nicht ganz sicher bin, ob nicht vielleicht, was ich als Unter- 

 lippe beschrieb, der Sporn sei ; kiinftige bessere Exemplare 

 werden das entscheiden und vielleicht eine Aenderung des 

 Namens nothig machen." An examination of the specimens 

 in the Kew Herbarium, collected by Hostmann, confirms the sup- 

 position here expressed, that the remarkably large, saccate, 

 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 corolla, I have not
