SPECIES, VARIETIES, AND 

 HYBRIDS. 



ACACALLIS. 



A monot}'pic genus of the tribe I'amica:, from Brazil, 

 The generic name is of doubtful origin. The species is a 

 stove, epiph}-tal Orchid, with a short, leafy stem, at length 

 thickening into a pseudo-bulb. It is distinguished from 

 Again'sia by the curious lip appendage, and b}' the large 

 auricles of the column. It requires to be cultivated 

 suspended in a moist position of the stove or East Indian- 

 house. On account of its climbing habit it is best 

 attached to a raft. It is rarel)- met \y\\h in cultivation, 

 and has become almost extinct in this countr)'. 



A. cyanea [Lindl. ). — The flowers of this species have been 

 described as being of the colour of "the well-known Vanda 

 cariika. There are, however, darker blue blotches, quasi- 

 tessellated over the flower. The lip is veiled, and has two very 

 small basilar teeth, and then a veiled middle lacinia that is 

 sacciform, bordered with most remarkable long bristles, and with 

 a deep violet blotch on its middle part beneath. The white 

 column has two cartilaginous, quadrate arms close to the 

 sti^matic hollow." 



ACAMPE. 



About nine species of stove, epiphv'tal Orchids of the 

 tribe Vandecs are included in the genus Acaiiipc {Lindl.). 

 The}' are mostly natives of the East Indies and Southern 

 China, and are closely allied to Saccolabiiiin. Indeed, 

 Hooker, in his " Flora of British India," includes them 

 under that genus. The name is derived from akmnpcs, 

 inflexible, and is in reference to the brittleness of the 

 flowers. Flowers much smaller than in Vanda, shortly 

 pedicellate ; .sepals free, sub-equal, somewhat fleshy ; petals 

 similar, but rather narrower ; lip sessile at the base of the 

 column, continuous, spreading, saccate or conico-spurred 

 at the base ; column short and thick ; peduncles lateral, 

 ricrid short and simijlc, or elongated and panicled ; leaves
