 synonyms and description). 



Var. picta ; pseudobulbis orbicularibus compressis, foliis brevioribus acutissimis, 

 sepalis petalisque pulcherrime maculis purpureo-atrosanguineis pictis. (Tab. 

 nostr. 5419.) 



This most lovely state of Burlingtonia decora, as we believe 

 it to be, was received from Brazil by Mr. Bateman, in whose 

 Orchideous House it flowered in October of the present year, 

 and was very attractive from its gracefulness, and the rich deep- 

 purple mottling of the sepals and petals, on a pure white 

 ground, so unlike the pale, dull, pinkish, uniform spotting of 

 the B. decora, given at our Tab. 4834. Moreover, the foliage 

 is considerably different from that of the latter plant, shorter, 

 and more acute ; exactly resembling that of Burlingtonia rigida 

 of Lindley, in ' Sertum Orchidaceum,' f. 36 ; a species on which 

 we have already offered some remarks under our Tab. 4834.*

* Burlingtonia decora has been given in the 'Flore des Serres,' vol vii. t. 716 

 That has the elongated pseudobulbs and elongated leaves of our first figure ; but 

 the sepals and petals are all over purple, with deeper small, and nearly uniform 

 spots of the same colour. I fear the species is exceedingly variable.
