far south as Buenos Ayres. Mr. Gardner found it on 

 trees in marshes at the foot of the Organ mountains, (no. 

 5635 of his herbarium). The size of the leaves is much 

 aflPected bv situation ; in all cases, however, they seem to 

 be broader at the base than at the point. So far as the 

 character of Count Hoffmannsegg's C. vestalis can be 

 judged of, that plant is the pale C. intermedia. 



11. C. Harrisoniana (Bateman in Bot. Reg. sub t. 1919.); 



" foliis anguste lanceolatis," sepalis oblongis apiculatis, 

 petalis ovalibus, labelli trilobi lobis lateralibus rotundatis 

 intermedio angusto crispo 1^ longioribus : lineis pluribus 



elevatis per totam axin lamellis nuUis. Brazil. 1 



only know this plant from two flowers given me by Mr. 

 Bateman. They have much shorter and broader sepals 

 than C. Loddigesii, the petals are much broader, and the 

 proportion between the middle lobe of the lip and its 

 lateral lobes is quite different. Besides which, certain 

 elevated lines run all the way from the base to near the 

 apex of the lip. The flowers are lilac ; the tip with a 

 deep blotch within the margin. 



12. C. Forbesii (Lindl Coll. Bot. sub t. 37. Bot. Reg. t. 



953. Lindl. no. J. Bot. Cab. t. 1152.) ; caulibus elon- 

 gatis teretibus, foliis 2 oblongis, sepalis petalisque lineari- 

 oblongis obtusis subsequalibus, labelli trilobi lobo medio 

 cordato subrotundo-ovato argute dentato undulato apicu- 

 lato : lateralibus minoribus rotundatis planis, lineis 4 

 elevatis pone basin lamellaque membranacea utrinque, 

 columna basi lineis 5 elevatis quarum duse majores cris- 



tata, clinandrii cardine tuberculo corrugate acuto. 



Brazil. Flowers greenish yellow. Lip with bright 



orange brown veins. Very near C. Loddigesii. 



13. C. maritima (Lindl. in Bot. Reg. sub t. 1919.) ; pedun- 



culo unifloro, caule subclavato, foliis binis ovalibus ob- 

 tusis spatha parum longioribus, sepalis oblongis acutis, 

 petalis lanceolatis falcatis obtusis, labello trilobo (nudo ?) ; 

 laciniis lateralibus erectis rotundatis intermedia dilatata 



denticulata emarginata. Sea-beaten rocks, Buenos 



Ayres. Flowers fine, rose-coloured, usually in threes ; 



many varieties. Its small leaves, dwarf habit, and one- 

 flowered peduncle, mark this, of which I have only seen 

 one specimen with a single flower. Possibly it is one of 

 the many varieties of C. Loddigesii.
