 I am afraid tbere is no doubt about ail the>e plants being the same. The iden- 

 lily of B. maculaia and guitaia has been overlooked, I presume, in consequence of 

 the figure in the Hot. Mag. having been represenled with revolute sepals and peials, 

 a circunisiance unknown among Brassias. I have lalely had an opportunity of exa- 

 mining a specimen in the possession of liis Grace the Duke of Nonhumberland, and 

 I lind that this part of the figure is wholly erroneous. The sepals and petals are 

 straight, and in ihe usual state of disproportion remarked in ihe genus. It is much 

 handsomer, and more rare thanguttata; which, however, is ajfine variety, with greenish 

 jellow flowers spotted with purple or green ; ihese vary greatly in size ; in Hart- 

 wcg's wiid specimens froni the Chono they are very small , in a specimen found by 

 Mr. Skinner at San Salvador iwice as large , and in a specimen before me, from the 

 garden of the Horiicuitural Sociely, larger than even the last.

(A.) Flowers bright yellow., sweet-scented , spotted wilh brown; the lip whole- 

 coiourcd. Laieral sepals not twice as long as the lip. 



(B.) macroslachya. Flowers bright yellow , slightly spotted wilh brown; lip much 

 paler. Lateral sepals very acuminate, ihree or four lime^ longer than ihe lip.

 (C.) pumila. Flowers pale yellow, stained wilh dull purple at the base of llie se-

 at base, more ihan half as iong as tiie laieral sepals.

 That all ihe.^^e plants are forms of ihe same species is I fenr undeniable . noi- 

 withstanding ihe great dilTerences in colour and the size of Ihe parls, cspecially in 

 Ihe leiiglh of llie laieral sepals, which in- niacroslachya are flve or more inches long. 

 AII are very near B. caudata itself, but appear to waiit the siibulatc poiiil o( the lip. 

 and ibe aristate sepals of ihat spccics. From B. L.iwrcnceana ihe ihreo leeih (Hvo 

 like horns. one small and inlermediate) standing upon ihe .sloping lamellae may be 

 rcgarded as ilie main differences. As to puiniia which hns pale yellow flowers 

 slained with dull purple at the base of the petals. but no purple on ihe sepals , and 

 ihe lip very slighily tinted , it is remarkable for a pair of somewhat transparenl leeib 

 wbich stand up in front of the two litile customary lamellae.
