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. now "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 1 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 

 jointed at the base, pollinia two; stigma shortly transverse: ovary 

 fleshy, flattened, sometimes slightly two-edged, incurved, 3-3.5 cm. 

 long, 5 mm. wide; capsule elongated.

 in bloom, July; London Creek, May; Deep Creek, June (545). 



Plate 3. Vanilla articulata. Cluster of flowers; e, lip; a, n, sepals; d, petal ; o, 

 column, side view; v, column, front view; m, cross section of buds. 



Cranichis sp. ? Near C. tenuis Reich. Leaves lanceolate, 6-8 cm. 

 in length; petioles equaling or exceeding the leaves; scape very 

 slender, few-flowered, 22 cm. in length, few small sheathing scales. 

 Two specimens only, Conch Sound, May (567). 



Cranichis sp. ? In fruit, possibly C. muscosa Sw., but the scape is 

 much more densely flowered than in Wright 620 from Cuba. Conch 

 Sound, March (417). 



Stenorhynchus orchioides Rich. Not common. Flowers 

 greenish. Conch Sound, May (412). 



Gyrostachys Peruviana (Aubl.) Kuntze? Common and vari- 

 able. Collected on both sides of Andros, Conch Sound, March; Red 

 Bays, April (399, 574). Bracts more acuminate than in Wright 3296.
