Upper Guinea. Sierra Leone ; cultivated specimens, Don ! Loddiges ! 

 Cameroons, Braun. 



Flowered in the collection of the Horticultural Society in 1824. 



Onlv kuowu to me from garden specimens. The flowers are a little smaller than 

 those of P. odorata, Lindl., and the front lobe of the lip is a little smaller, and has a 

 much shorter keel. 



21. P. tessellata, Lindl. in Joum. Linn. Soc. vi. 130. Stems 

 leafy, 3-6 in. long, slightly swollen at the base. Leaves oblong, or 

 elliptic-oblong, obtuse or subobtuse, 4-8 in. long, f-lj in. broad.

 almost at the base, many-flowered. Bracts subulate-lanceolate from a 

 broader base, acuminate, recurved, |-1 J lin, long. Pedicels 2-2 J lin. 

 long. Dorsal sepal ovate-oblong, subobtuse, 1-1 J lin. long; lateral

 somewhat incurved, 1 lin. long. Lip trilobed, Ij lin. long; side lobes 

 broadly oblong, obtuse, somewhat incurved ; front lobe suborbicular or

Upper Guinea. Niger Delta : mouth of the Nun River, Mann ! 



Iiower Guinea. St. Thomas : Angolares ; at Lagoa and Angra de S. Joao, 

 Quintas, 8! 84! Angola: Golungo Alto; at Cungulongo, on old tree trunks, 

 Welwitseh, 655 ! Pungo Andongo; at Mata de MutoUo, Welwitsch, 704! 



I am unable to find any character to separate P. Hypocrita, Reichb. f. The 

 absence of tessellation in the flowers is of no importance, as this character only appears 

 in the dried specimens.
