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. central! emarginato, calcari basi 

 saccato-conico ultra porrecto cylindrico apice acutato calycis lobum 

 inferiorem 2-3 -plo excedente. 

 Ad fluvium Cosanga, Pro v. Ecuador, legit Prof. Jameson. 

 U. rbizomate 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 bracteolis geminatis angustioribus sequilonga, 

 omnes basifixse et quam pedicellus breviores. Calyx 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 aequilongo continuum. Capsulam maturam baud vidi. 

 Folia 6-10 lin. longa, 1-1 1 lin. lata. Bractea 3-3| lin. longa. A basi 

 calycis ad extremum calcaris 6-8 lin. (Tab. I. fig. 1. Planta magni- 

 tudine naturali. a, a. flores integri ; b, pistillum ; c, folia ; d, ampullae 

 sub lente auctse, et e, eaedem nascentes.) 

 Much smaller and more slender than TItricularia tmifoUa, Euiz 

 and Pavon, and U. montana, Jaeq. * ; 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 TItricularia collected by Eichard 

 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 tbe genus adopted by Benjamin, in 

 his Monograph of the Brazilian species in the 'Mora' of Von 

 Martins, 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 ampullae and of leaves at the time of flowering, are 

 calculated to mislead. 



* I am not aware that a specific difference exists between these plants.
