164. CATASETUM poriferum. 



\ C. porifi 



carnoso ovato medio nectarifero, dente baseos ovato incurvo, col " 

 cirrhos^. 



umiia 



This is a remarkable species, sent to Messrs. LocIdi"-es 

 from Demerara by Mr. Schomburgk. In its manner*of 



growth and general appearance it agrees with Catasetum 

 deltoideum, like which its flowers are richly spotted with 

 deep purple broken fasciae, closely arranged upon a clear 

 green ground. The difference between these two species 

 resides in the lip, which, in the present plant, is dull green, 

 nearly flat, deeply cordate, truncate at the apex, with an 

 obscurely crenated margin ; at its base is an elevated yellow- 

 tipped broad tooth, and at its apex an ovate, yellow, fleshy, 

 elevated lobe, in the middle of which is a pore secreting 

 honey. The sepals are oblong, the petals narrow-lanceolate, 

 the column just as in C. deltoideum.

165. PLEUROTHALLIS muscoidea. 



i| P. muscoidea ; caespitosa, acaulis, folio ovali biconvexo, pedunculo setaceo 



bifloro, perianthio explanato ringente, sepalis Hneari-lanceolatis laterallbus 

 basi ima connatis, petalis multo mlnoribus conformibus, labello oblongo- 

 lineari obtuse canaliculato, polliniis 2 pyrifonnibus connatis. 



This is the most tiny Orchidaceous plant yet discovered. 

 It has no stem ; the leaves are two lines and a half long ; 

 the peduncle as fine as a hair, and about four lines long. 

 The flower is dull purple, with a pale orange-coloured margin 

 to the sepals and petals ; the lip is linear, obtuse, richly 

 stained with purple, dull orange along the middle and at the 

 edge, very slightly cordate, and contracted for a short space 

 in the middle. For a specimen I am indebted to Messrs. 

 Loddiges.

|- ^ N. punctata ; labello unguiculato cordato-ovato obtuso basi calloso marginc 



reflexo, sepalis petalisque obtusis; rachi flexuosS. 



I believe the original species to which this name belongs 

 is lost to our gardens, and its place has been taken by other
