1 gladly avail myself of Mr. Bateman's permission to 

 publish the foregoing memoranda. The readers of the Bota- 

 nical Register will remember that another Maxillaria Skinneri 

 has already been described in it (1840, miscellaneous matter, 

 no. 101) ; but that plant, nearly allied to M. aromatica, is 

 not what Mr. Bateman had called after Mr. Skinner, but a 

 species far inferior in beauty, though very handsome. A 

 figure of it will appear in the Register of next month.

14. ONCIDIUM bicallosum. 



Lindl. in Benth. Plant. Hartweg. ined. 



Among the numerous fine things found in Guatemala by Mr. 

 Skinner, there is not many which are more deserving cultiva- 

 tion than this, which has so much the habit of O. Cavendishi- 

 anura as to seem a mere variety of it, but which is in reality 

 a quite distinct species. It was also met with by Mr. Hartweg. 

 The flowers are fully two inches in diameter, which is four 

 times the size of O. Cavendishianum ; they appear in a dwarf 

 erect raceme, not panicle ; they are of a rich yellow, with the 

 sepals and petals bordered with cinnamon colour ; the label- 

 lum has two very small lateral lobes, and for its crest it has 

 two distinct tubercles, the posterior double, the anterior 

 3-lobed, and the two separated by a considerable space. The 

 flowers are moreover slightly scented, which is not the case 

 with O. Cavendishianum. Many plants are doubtless in the 

 country ; but no one has succeeded in flowering them except 

 Mr. Bateman, who sent a fine specimen to the last meeting 

 of the Horticultural Society.
