rium fere equans. А basi calycis ad extremum corolle calearis circa 
3 lineas. 
A remarkable little plant, forming patches one to two feet in 
diameter in a sandy islet in the Falls of Panuré. Sufficiently 
distinct in its peltate orbicular leaves from all the smaller species 
with which I am acquainted. 
No. 1050. U. Spruceana (Benth.). Scapo 11-3 unciali unifloro, pe- 
dicello e bractea marginibus ejus in vaginam parvulam infundibulifor- 
mem connatis, calycis lobis rotundatis integris, corolle labio superiore 
oblongo emarginato v. retuso calycem fere duplo superante, labio 
inferiore antice leviter retuso v. subintegro, calcari crasso obtuso 
dependente v. paululo curvato. labium corolle inferius zquante v.

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 sequalibus obtusissimis, inferiore quam calcar 2-3-plo bre- 
viore. Corolla alba, fauce macula flava notata. Stylus primum ova- 
rium fere sequans. А basi calycis ad extremum calcaris corolle 14-2 lin. 
The singular, minute, sheath-like involucre may perhaps result 
from confluent bract and bracteolm. Spruce sent it over under 
the MS. name of U. uniflora; this, however, was preoccupied by 
a plant of Robert Brown’s. 
No. 2858. U. trichophylla (Spr.). Scapo (5-12 unc.) pauci-multifloro, 
foliis capillaceo-gracillimis inter scapos erectis sursum pinnatifidis seg- 
mentis utrinque paucis angustissime linearibus simplicibus v. dicho- 
tomis, bracteis mediofixis, pedicellis remotis brevibus erectis, corolla 
labio superiore integro elliptico v. ovato obtusissimo, calcari porrecto 
conico-cylindrico apicem versus oblique acutato labium corollæ inferius

Radix fibrillis utriculiferis instructa. Folia 4-5 uncialia. Bractee basi 
obtuse apice acute v. obtusiuscule. Pedicelli breves calycem sequan- 
tes v. vix duplo excedentes. Calyx lobis subeequantibus obtusissimis 
altero emarginato. Corolla flava, calcari 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), В. pedicellata. Scapo 1-1}

Although differing much from U. neottioides in habit, I do not 
discover technical characters sufficiently marked to warrant its
