Maxillaria barbata Knw, Weslc, Phyt. 7 : 



Pseudobulbis aequaliter quadrangularibus, corrugatis, vaginatis, foliis 

 ovatis, cosfatis, aculis; floribus racemosis; sepalis inaequalibus , petalis 

 majoribus, lateralibus explanatis, apice subinvolutis; labello cucuUato, 

 trilobato, barbato, margine crispo, apice gibboso, disco carnoso. 



,, Flowers about 8, yellow, disposed in a raceme. Labellum bearded, cucullate, 

 threelobed , and liaving a lleshy excrescence on ihe disk; darker in colour, ihan the 

 sepals and pelals and marked in ihe centre and on the lateral lobes with a dark 

 purple spot. Clinandrium eniire. Caudiculae two , distinct. Gland transverse, Pol- 

 lenmasses compressed , sulcate. Aniher case onecelled and minutely pubescent 

 like the column.'- 



„ This species in habit, in ihe form of the pseudohulbs and in the foliage, is very 

 similar lo Max. tetragona, but ihe flowers a^-e altogether dilTerent, and bear resemblance 

 to these of MaxHlaria aureofulva Hook. fig. in ihe Floral Cab. 11. pl. 83" I. c. 



This plant apiiears lo be identical wiih M. viiellina. Wiih respect to its supposed 

 double caudicuiae I must however obscrve ihat ihey are no more than the elastic 

 cenire which holds ihe pollenmasses of all 0. pl. Vand to their common caudicula, 

 and ibal they are very differenl from those truly doublc caudiculae properly so called, 

 whicb exist in Bifrenaria.
