86 LYCASTE. 



were sent to us from the Eoyal Botanic Garden at Glasnevin by 

 Mr. F. W. Moore^ who called our attention to the confusion that 

 has long existed respecting this species. On comparing the flowers 

 with the figures of Maxillaria ciliata in the Botanical Register and 

 Botanical Magazine, we wore satisfied that the Glasnevin plant must 

 be referred to that species. Now Lindley (Bot. Reg. 1844, misc. 

 p. 43) reduced M. ciliata to a synonym of M. Barringtonice of 

 LoddigeSj* when he removed the latter to Lycaste; this is a West 

 Indian species figured and described in Hooker's Exotic Flora as 

 Dendrobium Barringtonice, and in Smith's Icones as Epidendrum 

 Barringtonice. Unfortunately both Loddiges' and Hooker's figures 

 are imperfect, but there is sufficient evidence in them to raise a 

 doubt whether the Peruvian Lycaste ciliata and the West Indian 

 L. Barringtonice are one and the same species, a doubt that we are 

 unable to clear up. It is scarcely necessary to add that the plant 

 figured as L. BarringtonicB in the Botanical Magazine, t. 5706^ is not 

 the West Indian species but the Peruvian L. costata. 



Lycaste ciliata was first gathered by the Spanish botanists, Ruiz 

 and Pavon, at Mufia and Chinchao, in Peru, more than a centmy 

 ago. The plant is of no horticultural merit whatever; it is in- 

 troduced here solely with the view of bringing under notice the 

 confusion that exists respecting it. 



L. costata. 



Pseudo-bulbs 3 — 5 inches long, compressed with 3 — 5 strong ribs 

 in each of the flattened sides, diphylloiis. Leaves 20 — 25 inches long 

 including the rather long channelled petiole. Scapes about one-fourth 

 as long as the leaves; bracts large and slightly inflated. Flowers 

 4 inches across vertically, ivory-white ; dorsal sepal oblong, acute, 

 incurved over the column ; lateral sepals oblong, falcate, sub-acute ; 

 petals linear-oblong, sub-acute, lying immediately under the dorsal sepal 

 and incurved over the column in the same way; lip three-lobed, the 

 side lobes sub-rhomboidal with the front angle very acute ; the inter- 

 mediate lobe ovate-oblong with the side margins fimbriate ; plate of 

 disk very thick, grooved and emarginate. Column triquetral, bent, hairy 

 at the base.
