contracted at the base with a sUy;-ht S-hke curvature. 

 Stems bearing the leaves in two rows. /. liucivis requires 

 warm intermediate-house treatnient.

KEFERSTEINIA {R.-ho. /.). This is now included under 

 Zygopetalum. 



LACUNA. 



Two species of epiphytal Orchids, of the tribe J'andiw, 

 form this genus, which was founded b)- Lindle\-. The 

 generic name is supposed to mean nati\e of Lacedasmon ; 

 it is one of the names of Helen of Troy. As, however, 

 this would imply great beaut}-, the name cannot be said 

 to be well bestowed. The species are natives (if Central 

 America. The\' are best accommodated in baskets or 

 pans, and treated like Eycaste and Aiiguloa, to which 

 genera the}- are closel}^ allied. 



L. spectabilis (Lindl.). — Flowers pinkish-white, dotted with 

 purple, produced in ^Slay in loose pendulous spikes ; sepals

L.CLIA. 



In the introductor}' notes on the genus Cattlcya, 

 reference was made to the nearness of the relationship 

 between that genus and Lcclia (Lindl.). The latter is 

 separated into two groups, viz.: A) all those species 

 which are natives of Mexico and Guatemala, including 

 albida, anceps, autuiiinalis, fiirfiif-acea, majalis, ruhcscens, and 

 siiperbiens ; (i) tho.se kinds which are similar in habit and 

 flowers to the Cattleyas, and of which Bootliiana (lobata), 

 crispa, Donnaniana, elegans, and Perrinii, are examples. 

 The genus, which is a very showy one, belongs to the tribe 

 Epidendrece, and the name it bears is that of a \-estal
