“ Perigonii conniventis foliola exteriora angusta, navicularia, carinata, 
basi subcohærentia, lateralia labello supposita, in unicum connata, basi 
in calcar obtusum, breve producta; interiora latiora, libera.  Labellum 
integrum, supra basin columna continuum, basi brevissime bifidum, 
liberum, disco calloso, puberulo, longitudinaliter bicostato, antice biden- 
tato, dentibus obtusis, conniventibus ; costis infra medium bicornutis ; 
lamina apice emarginata, subexserta. Columna semiteres, nuda, labello 
subduplo brevior. Anthera semibilocularis. Pollinia 2, sphærica, solida, 
caudicula lineari instructa, glandula parva, obovata. — — Herba caracasana, 
epiphyta ; rhizomate cæspitoso ; pseudobulbis subnullis ; foliis solita- 
riis, coriaceis, carinatis, basi vaginis squamæformibus, conduplicatis, 
involucratis ; racemo radicali ; floribus compressis, flavidis. 
S. Ottonis; folis oblongis, coriaceis, leete-viridibus, margine acutis, sub- 
tortuosis, apice conduplicato-acutissimis, recurvis; racemo radicali 
subramoso, foliis parum longiore; foliolis perigonii interioribus obovatis, 
obtusis, intus longitudinaliter purpureo-striatis, sparsim pilosis." 
This new genus of Orchidaceous epiphytes has been 
found in the Caraccas by Mr. Edward Otto, and by him sent 
to the Royal Botanic Garden, Berlin, where it has flowered. 
It occurred on the stems of trees in dense forests, 5,600 
feet above the level of the sea. ‘The habit of the plant is 
that of Burlingtonia, to which it approaches very nearly. 
The flowers are yellow, rather more than half an inch long, 
and do not spread flat, but are half closed up. 
20. TILLANDSIA vitellina. 
Link, Klotzsch & Otto, Icones plantarum, t. 40. 
T. vitellina ; “ subacaulis; foliis latis, oblongo-lanceolatis, acuminatis, sub- 
coriaceis, integerrimis, leete-viridibus, utrinque glaberrimis ; spica multi- 
flora terminali, subramosa, pendula ; floribus sessilibus, bracteis parvis, 
foliaceis suffultis ; perigonii foliolis exterioribus calycinis saturate viri- 
dibus, interioribus longioribus vitellinis, apice dilatatis, patentibus ; 
genitalibus inclusis ; filamentis subulatis ; germine pyramidali-trigono ; 
stylo subnullo; stigmate trilobo, lobis linearibus divaricatis; ovulis 
apice papposo-comosis.” 
A smooth-leaved stove plant, with the habit of a small 
Pine-apple, and little yellow flowers growing in a nodding 
slightly branched spike. This also is one of Mr. Otto's 
discoveries, having been found by him in Venezuela, growing
