148 FLORA OF NEW PROVIDENCE AND ANDROS 



greenish yellow flowers panicled; leaves equitant, recurved, rosulate 

 from flattened tubers (602). No. 750 collected at Mars Bay, Andros, 

 in July is probably a smaller specimen of the same species and No. 405 

 from Conch Sound, an Oncidium in fruit only, may perhaps be referred 

 to the same species. 



Vanilla articulata sp. nov. "Link-vine," "wormwood" 



A tall climber with aerial roots, growing over trees and shrubs, 

 aphyllous; stems jointed, joints fleshy, smooth, subangular, 2-3 dm. 

 in length; flowers in short axillary spikes, 6-12 flowered; bracts 

 broadly ovate or triangular, blunt, 5 mm. in length; flowers about 6 

 cm. long, fleshy, white with faint pinkish tinge, parts of perigone 

 jointed at the base; sepals erect, spreading, fleshy, oblanceolate, 

 involute at the tip, 3-4 cm. long, about i cm. wide ; petals oblanceolate 

 or spatulate, equaling the sepals but thinner, keeled on the back; 

 lip adnate to the column more than two-thirds of the way, convolute, 

 broadly obovate or triangular, about 3 cm. in width, channeled on the 

 back, three-lobed, lobes obtuse, crispate, lateral lobes papillose below, 

 central lobe sparingly crested above, bearded below (thick tuft of cilia 

 5-6 mm. long), column elongated, about 2.5 cm.; anther terminal

 greenish. Conch Sound, May (412).
