which the top of the column is figured at fig. 1. of the accom- 

 panying plate, which is nearly allied to this, hut appears dis- 

 tinct. It has white sepals, and rose-coloured straight not 

 curved petals^ It requires further examination hefore its true 

 value can be determined ; it is, however, very pretty. 



Considering the number of species, or supposed species, of 

 this glorious genus, now in our gardens, and the length of 

 time that has elapsed since any arrangement of them has 

 taken place, it seems desirable that they should be brought 

 into one view ; especially as nearly all of them exist in our 

 gardens. And I am the more induced to rearrange the genus, 

 because I find some of the remarks made at t. 22 of the 

 Sertum erroneous,— especially the statement that C. maxima 

 is a Lselia, a mistake the origin of which I cannot trace. 

 The division there suggested among the species is too arti- 

 ficial ; that now proposed will be found more natural. 



There is no character by which Cattleya and Lselia can 

 be distinguished except the number of pollen-masses, which 

 are four in the former, and eight in the latter. The flowers 

 of Laelia are usually indeed in a raceme elevated on a long 

 graceful stalk ; but such is not the case in Lcelia Perriniiy 

 originally described by me as a Cattleya, and subsequently 

 regarded by Sir W. Hooker (Bot. Mag. t. 3711) as a variety 

 of C. intermedia j nor in L. virens.
