326 Prof. Lindley on some Orchidaceous Plants 



of that little-known island, and how much is still open to dis- 

 covery by the diligent traveller. 



Of the 80 species here enumerated 21 are undoubtedly 

 unpublished, wliile others, such as Pleurothallis testafolia, 

 Microstylis umbeUulata and spicata, Camaridium vestitum, and 

 Chloidia vernalis, have scarcely been seen by any botanist since 

 the time of Swartz. The localities are copied exactly from 

 Mr. Wright's tickets, which seem to have been written at the 

 time the plants were gathered, — a circumstance that gives them 

 much value in all that concerns colour and form. They also 

 serve to establish with certainty the native country of some 

 species previously known only in gardens, where errors so con- 

 tinually occur in that respect. Examples of this will be found 

 in the case of Masdevallia fenestrata, Prescottia culorans, and 

 Spiranthes truncata. 



-f Pletjrothallis Wilsoni ; (prorepens) folio ovali tridentato caulis 

 longitudine, pedicellis unifloris, bracteis 2 minutis oppositis altera- 

 que sub flora glabro disepalo, petalis oblongis acutis, labello ovato 

 angulato obtuse, capsula ovali glabra. 



" S^. Isabel, on rocks in woods ; on trees in dense woods else- 

 where." (668.) 



Near P. angustifolla, which has serrated petals. There is a spe- 

 cimen from Jamaica, in bb. Hooker, gathered by ^Mlson. 



Pleurothallis rubigena ; (muscosa) folio oblongo obtuso mar- 

 ginato pedicello filiformi stricto medio bracteato duplo breviore, 

 ovario triptero obovato, sepalis 2 acuminatis glabris, petalis ovali- 

 bus acutis, labello rbomboideo acuminato obtuso trivenio. 

 "Mountain tops, on trees in dense woods." {Qb7 •) 



Diifers from P. acuminata, Focke, in having much larger leaves, 

 longer pedicels, only 2 sepals, &c. P. alata, Rich, and Gal., appears 

 from their unpublished figure to have a large bract beneath each 

 flower. 



Pleurothallis Grohyi, Lindl. in Bot. Reg. t. 1707. A solitary 

 specimen, mixed with others under the same number. See P. 

 longilahris. 



"Top of Loma del Gato, on branches of trees." A solitary spe- 

 cimen. (651 .) 



«r Pleurothallis trichophora ; folio ovali obtuso cauli laxe vaginato 

 paulo breviore, racerao longissimo capillar!, floribus longe distanti- 

 bus glabris, sepalis disjunctis ovatis obtuse acuminatis, petalis 

 linearibus acuminatis, labello unguiculato subrotundo ovato 2-cris- 

 tato, columna cucullata crispa triloba.
