below, and I avail myself of the same opportunity to charac- 

 terise two or three others with which 1 am acquainted. 

 Beautiful as are C. labiata, crispa, and Loddigesii, C. coc- 

 cinea and bicolor described below, are not at all inferior to 

 them, and moreover there is in the possession of Messrs. 

 Loddiges a very distinct crimson-flowered fragrant species, 

 found in British Guiana by Mr. Schomburgh, with which I 

 have not sufficient acquaintance to define it. 



C. ovaia ; foliis binis ovatis obtusis caule cylindraceo longioribus (?) sepalis 

 petalisque lanceolatis acuminatis, labello nudo trilobo laciniis lateralibus 



apice intermediaque oblonga obtusa denticulatis undulato-crispis. St. 



Catharine's, Brazil (Mr. Hindes). A very fine species in the way of 



C. labiata. 



C. bicolor ; foliis oblongo-loratis caule tereti elato triple brevioribus, sepalis 

 lanceolatis falcatis acutis, petalis parum latioribus subundulatis obtusis, 



labello indiviso piano apice dilatato rotundato crenato convexo. Brazil, 



Descourtilz in Bibl. Deless. t. 49. Stems 2-3 feet long. Sepals and 



petals tawny; labellum bright purple, with a lanceolate streak in the centre, 

 white slightly spotted with purple. The flowers are slightly fragrant. 



C. maritima ; foliis binis ovalibus obtusis spatha parum longioribus, caule sub- 

 clavato, sepalis oblongis acutis, petalis lanceolatis falcatis obtusis, labello 

 trilobo (nudo?); laciniis lateralibus erectis rotundatis intermedia dilatata 



denticulata emarginata. Sea-beaten rocks, Buenos Ayres, (Tweedie, in 



herb. Hooker.) Flowers fine, rose-coloured, usually in threes ; many varie- 

 ties. Its small leaves sufficiently mark this, of which I have only seen 

 one specimen. 



C. coccinea ; foliis solitariis oblongis acutis caulibus ovalibus teretibus longiori- 

 bus, floribus solitariis, spatha nulla, sepalis lineari-oblongis obtusis rectis, 

 petalis triple latioribus, labello ovato basi cucuUato indiviso apice piano 



sepalis breviore. Brazil, Descourtilz in bibl. Deless. t. 10. Stems 



2 or 3 inches high. Flowers brieht scarlet, 3 inches across. A most 

 remarkable and beautiful species. 



C. Harrisoniana (^Bateman in litt.) ; foliis anguste lanceolatis, racemo 1-4- 

 floro, sepalis petalisque patentibus his subrotundo-ovalibus, labello subtrilobo 



verrucoso. Bateman. Brazil, Mr. Harrison. Very near C. Lod- 



digesii.
