Peduncnlo multifloro ( — 15.), floribus parvnlis (illos Br. glumaceae 

 aequantibus), inversis, secundis, bracteis triangulis, concavis, aculis, pe- 

 dicellos non aequantibus, perigonii phyllo supremo lanceolato acumi- 

 nato, basi dilatato, pbyllis lateralibus externis subaequalibus , longiori- 

 bus, lateralibus internis triangulo-lanceolatis, a lata basi acuminatis, 

 quam phylla exlerna brevioribus, labello aequalibus , labello oblongo 

 acuminato, basi cuneato, per totum discum valde velutino, lamellis ba- 

 seos distinctis, basi rotundato-elevatis, apice retrorso-falcatis , papillis 

 puberulis; gynostemio humili a foveae sligmalicae basi labellum versus 

 antrorsum oblique decurrente. 



Die Biutbentrauhe gewahrl die Erscheinung, dass die unteren seitlichen Hullblatter 

 alle nach einer Seite, die oberen nach der anderen gelegt sind. — Ich kann mit 

 dieser Art nur zwei in Beziehung bringen , die obscure Br. 'pumila Barker scheint 

 HerrlProf. Lindley mit der mir wohlbekannten Br. angusta fiir idenlisch zu halten 

 (vory near Brassia angusla). Sie hat ein labellum panduratum und vor den Kielen 

 kculige Zaline. Br. giumacea dagegen zeichnet sich diirch die sehr langen Ueck- 

 blalier und bedeutend langgesliclte Fruchtknoten sogleich entschieden aus , auch hat 

 sic eine ganz kahle Lippe. Ecuador am Punt St. llelena und bei Tipi Happa. 1000— 

 2000'. April. 



116. _ t. — ONCIDIUM RACEMOSUM Rchb. fil. Mss. Huc : Solenidium Lindl. Orch. 

 Linden. 1846. N. 79. p. 15: 



Sepala et petala aequalia, explanata, libera. Labellum ungue longo 

 canaliculato apice bidentalo, lamina subrotundo ovata obtiisissima. Co- 

 Iiimna aptera haud pede producla, alata, apice biloba, lobis lateralibus 

 rotundatis dorsali lacero. Pollinia 2, cereacea, in caudicula incurabentia, 

 glandula parva subrolunda. 



Foiia cnsiformia , tenuia , basi anguslata. Raccnius laxus mulliflorus, Bracleae 

 minutae, pedicellis pracilibus, sigmoideis pluries breviores. 



This curious genus is ncar Oiicidium and Brassia. from bolh of which it is distin- 

 cuished by it narrow slalked warlless lip , ihreelohod anthcrbed , and very peculiar 

 pollenmasses, which are bent down upon their caudiclc while in thc anther. 



Solenidium raccmosum. ,,An epiph. from forests near Pamplona, al the heiglit of 

 8500'. Nov. Flowers yeliow, spotled with red. 



Paxl.FI. G. III. 102; The main diffcrence belwecn Solenidium and Oncidium consists 

 in Ihis: column is earless . has a ihin mcmbranous bordi-r , terminaling upwards in 

 a thin iriangular loolh, nnd rounded of above ihe base; bencalh ihe lower end of 

 ihc column siand a pair of dislinct but rninute glands, which must be analogous to 

 ihe column cars of Oncidium if ihere is any analogy belween them. The crest of 

 ihe lip which in Oncidium is amplccted of 3 or some olher uneven number of lu- 

 bercles is here replaced by a pair of long feathery plalcs, which stand considerably 

 above ihe lip ilself, and being free at the end look in profile like a pair of shaggy 

 ears. All ttiis is very unsuccessfully repre»>cntod on our plute.
