panicles of flowers ; these have a broad lip, which is prominent 

 owing to the length of its claw. They are of Tropical American 

 or West Indian origin. We specially recommend the species 

 named below. 



Culture. — These plants succeed best on a block, with a little 

 live sphagnum moss round the roots, which require to be kept 

 moist nearly all the year round. We have found them do 

 well in the coolest house, suspended near the glass, where 

 they continue in bloom for several weeks at a time. They are 

 difficult plants to grow, for we seldom see them continuing to 

 do well — indeed we often find them flowering themselves to 

 death. 



I. paniculata, Lindley. — A charming small free-flowering 

 Orchid that ought to be in every collection. The leaves are 

 six inches high, and proceed from very slender stems which 

 scarcely form pseudobulbs. The flower scapes, which are a 

 foot and a half high and branching, proceed from the axils of 

 the leaves, the blossoms, produced twice a year, being of a 

 pretty blush white, the broad roundish bilobed lip having a 

 lovely purple spot on its base ; they vary, however, in colour, 

 some being almost pure white, some pencilled with rose, and 

 some white and yellow. According to Descourtilz, the scent- 

 less flowers remain fresh in their native forests from September 

 or October till the following May. — Brazil.

IpSEA, Lindley. 



{Tribe EpidendreEe, subtribe Erieae.) 



This small group of two species only is sometimes referred to 

 Pachystoma. The Ipseas are terrestrial plants, with tuberous 

 rhizomes, leafless scapes, and narrow lanceolate plaited leaves. 

 The lateral sepals are oblique at the base, connate with the 

 foot of the column, and saccate ; the lip is three-lobed, 

 the lateral lobes large erect, and the middle one oblong obtuse
