Kiiown only from ihe description in ihe worlc above quoted. Two varicties nro 

 menlioned ; one with a branched manynowered spike (,,near Oncid. oliissimum''), 

 the olher with a slender, allenuaied scape, and very slender llowers (,,n. gracilliniis"), 

 I'seudobulbs three inches and moro in length. Scnpe iwo feet high, purplish brown. 

 Flowers 3—5, large. showy, like a llger*s skin , having ihe smeli of ihe sweelest vio- 

 lets. Sepals ond petols yeilowish, variegated all over wilh chesnutpurplc tigrine- 

 spoi». Lip vcry large, yellow, not spotted. 



Il is siogular, thal a plant like this, used for decoralion under the name of „Floi 

 de Muerlos"* should have escaped all the numerous boianical collectors, who havo 

 visiied Mexico. It seems from the descriplion to be more iike an Odouloglossura. 

 than an Oncidium, and to be related to 0. grande. from which it certninly dilTers iii 

 very frogrant llowers , and lorge yellow spoiless lip (labelium maximuin luieura ioi- 

 moculatum).

 In reconsideriiifc ihcse cniically, I doubt iheir distinctness. They boih have iho 

 snme habit, and tlie same column nnd lip; bnt in B tbc crest is smooth and seven- 

 toothed. v.hilc in rclle.xum il is downy and five-iooibed. Dut I fear such distinciions 

 are nol permanent,
