OF UTRICULARIA FROM SOUTH AMERICA. 173 



rium fere aequans. A basi calyeis ad extremura coroUsc calcaris circa 

 3 lineas. 



A remarkable little plant, forming patches one to two feet in 

 diameter in a sandy islet in the Falls of Panure. Sufficiently 

 distinct in its peltate orbicular leaves from all the smaller species 

 with which I am acquainted. , 



No. 1050. U. Spruceana (Benth.). Scapo l|^-3 unciaJi unifloro, pe- 

 dicello e bractea marginibus ejus in vaginam parvulam infundibulifor- 

 mem connatis, calyeis lobis rotundatis integris, corollse labio superiore 

 oblongo emarginato v. retuso calycem fere duplo superante, labio 

 inferiore antice leviter retuso v. subintegro, ealcari crasso obtuso 

 dependente v. paululo curvato labium coroUse inferius aequante v. 

 parura excedente. Santarem. 



Scapus gracilis esquamatus basi fibrillis radiciformibus utriculiferis, foliis 

 in spec, nostris ut videtur tempore florifero desunt, bractea involucri- 

 formi basi in scapo continua margine supra leviter bilobata. Calyx 

 lobis fere aequalibus obtusissimis, inferiore quam calcar 2-3-plo bre- 

 viore. Corolla alba, fauce macula flava notata. Stylus primum ova- 

 rium fere aequans. A basi calyeis ad extremum calcaris corollse 1^-2 lin. 



The singular, minute, sheath-like involucre may perhaps result 

 from confluent bract and bracteolse. Spruce sent it over under 

 the MS. name of Z7. uniflora ; this, however, was preoccupied by 

 a plant of Eobert Brown's. 



Nb. 2858. U. trichophylla (Spr.). Scapo (5-12 unc.) pauci-multifloro, 

 foliis capillaceo-gracillimis inter scapos erectis sursum pinnatifidis seg- 

 raentis utrinque paucis angustissime linearibus simplicibus v. dicho- 

 tomis, bracteis raediofixis, pedicellis remotis brevibus erectis, corollae 

 labio superiore integro elhptico v. ovato obtusissimo, ealcari porrecto 

 eonico-cylindrico apicem versus oblique acutato labium corollse inferius 

 integrum subaequante v. vix excedente. Ad flumen Uaupes. 



Radix fibrillis utriculiferis instructa. Folia 4-5 uncialia. BractecB basi 

 obtusse apice acutse v. obtusiusculae. Pedicelli breves calycem aequan- 

 tes V. vix duplo excedentes. Calyx lobis subaequantibus obtusissimis 

 altero emarginato. Corolla flava, ealcari circiter 3 lin. longo. 



Spruce describes the remarkable and extremely slender leaves 

 of this plant as growing erect amongst the scapes. 



No. 3011. U. neottioides (A. St. Hilaire), p. pedicellata. Scapo I-H 

 unciali 2-4-floro interdum bifido, pedicelUs capsulam 2-4-plo ex- 

 cedentibus. 



In rupibus humectatis Monte Cocui, San Carlos. Flor. mens. vii. 



Although differing much from U. neottioides in habit, I do not 

 discover technical characters sufficiently marked to warrant its
