garden of the Horticultural Society in July, 1842. It is a 

 pseudo-bulbous plant, with a close raceme of very large pale 

 rose-coloured lemon-scented flowers, in form resembling Onci- 

 dium 'Lanceanum. It had been given by Mr. Barker to 

 T. Brocklehurst, Esq. of the Fence, from whose garden it was 

 contributed. At first sight this species would seem to be an 

 Oncidium ; but its lip has two parallel fleshy plates at the 

 base, which forms an acute angle with the column, and the 

 latter again has three wings, of which two are lateral and 

 one dorsal ; all which circumstances refer it to Odontoglossum, 

 in which, in the neighbourhood of O. pulchellum, it must be 

 placed. 



69. SARCANTHUS filiformis. 



S. filiformis ; foliis filiformibus, racemis 7-8-floris, sepalis petalisque reflexis, 

 labello apice ovato fauce utrinque bidentata, apice calcaris didymo, co- 

 lumiiJE facie glabra. 



A species of no beauty, sent to Col. Feilding from India 

 by Dr. Wallich. It has very small flowers, with chocolate- 

 coloured sepals and petals, and a pale yellow lip tipped with 

 pink. It is near S. teretifolius. 



70. EPIDENDRUM latilabre. 



E. (Euepidendrum) latilabre ; caule ancipiti folioso, foliis oblongis supremis 

 rotundatis latioribus, floribus umbellatis, labello duplo latiore quam longo 

 obsolete trilobo basi bicalloso, clinandrio laciniato. 



A plant of little beauty, resembling Epidendrum umbel- 

 latum ; from which it differs in its lacerated anther-bed, and 

 very broad lip, which is at least twice as wide as long. It is 

 chiefly remarkable for its extensive geographical range. The 

 plants in our gardens are all I believe from Brazil, where it 

 has been found by many travellers, (it is Prof. Gardner's 628). 

 But it is also a native of Dominica, whence I have specimens 

 from Prof. Henslow ; and Hartweg found it in the woods 

 near Samborondan in Guatemala. 



71. POLYSTACHYA clavata. 



p. clnvata ; foliis lineari-oblongis obtusis recurvis canaliculatis, panicula brevi 

 .stricta spicata ramis clavatis, labelli carnosi lobo medio emarginato cre- 

 nato lateralibiis brevibus acutis, disco farinoso basi convexo.
