170 MR. D. OLIVER, JUN., ON NEW SPECIES 
superiore amplo late ovato integro obtusissimo calycis lobum supe- 
riorem integrum ovatum obtusum superante, labio inferiore antice 
3-lobato lobis obtusis integris v. centrali emarginato, calcari basi 
saccato-conico ultra porrecto cylindrico apice acutato calycis lobum 
inferiorem 2-3-plo excedente. 
Ad fluvium Cosanga, Prov. Ecuador, legit Prof. Jameson. 
U. rhizomate gracili ad truncos arborum repente, ad scapum et folium 
unicum etiam e nodis fibrillas tenues utriculiferas cum ceterisque 
paucis incrassatis tuberculatis emittente. Folia semper e basi sca- 
porum ut videtur solitaria acuta v. obtusiuscula glabra in petiolum 
gracillimum attenuata. Scapus glaber interdum foliolis v. squamis 
1-2 parvis lineari-lanceolatis basifixis instructus. Bractea lanceolata 
v. ovato-lanceolata braeteolis geminatis angustioribus squilonga, 
omnes basifixæ et quam pedicellus breviores. Calyz lobis fere sequa- 
libus glabris ovatis v. vix subcordatis, obtusissimis v. lobo inferiore 
leviter emarginato. Corolla purpurea (Jameson, in lit.) labio supe- 
riore pro planta magno verosimiliter nonnunquam apice abrupte 
obtuso, labio inferiore calcari breviore: calcar apicem versus pilis 
sparse obsitum. Ovarium tempore florifero in stylo crasso brevi sed 
fere equilongo continuum. Capsulam maturam haud vidi. 
Folia 6-10 lin. longa, 1-13 lin. lata. Bractea 3-34 lin. longa. А basi 
calycis ad extremum calcaris 6-8 lin. (Tab. I. fig. 1. Planta magni- 
tudine naturali. a, a. flores integri; 5, pistillum ; c, folia; d, ampulle 
sub lente auctæ, et e, ezedem nascentes.) 
Much smaller and more slender than Utricularia unifolia, Ruiz 
and Pavon, and U. montana, Jacq.*; differing also essentially in 
the spur, which exceeds the calyx, the three-lobed lip of the 
corolla, and other characters. 
In enumerating the species of Utricularia collected by Richard 
Spruce, I desire to acknowledge the valuable aid afforded to me 
by the careful notes upon the plants in the fresh state, which, in 
accordance with the practice of that excellent botanist, accom- 
pany the specimens sent home by him. Comparatively few of 
them have been collected in sufficient quantity to supply the 
whole of his subscribers ; and of some the specimens have been too 
much injured, or are otherwise insufficient, for accurate determi- 
nation. Had the sections of the genus adopted by Benjamin, in 
his Monograph of the Brazilian species in the ‘Flora’ of Von 
Martius, recommended themselves to me as of practical use to 
botanists, I should probably have arranged these plants in accord- 
ance with them: some of these sections, based upon the presence 
or absence of ampulle and of leaves at the time of flowering, are 
calculated to mislead. 
* I am not aware that a specific difference exists between these plante.
