42 KUBIACEAE. 



17. ERNODEA* Sw. Prodr. 29. 1788. 



Glabrous, or somewhat pubescent, low shrubs, the branches erect, decum- 

 bent or trailing, with opposite, linear to lanceolate, nearly sessile leaves, the 

 stipules connate into a sheath; flowers small, solitary and sessile in the axils. 

 Calyx-tube short, the limb 4-6-parted, the lobes triangular to linear or subulate, 

 persistent. Corolla white to pink, the tube nearly cylindric, the 4-6 lobes nar- 

 row, revolute, valvate. Ovary 2-celled; style slender; stigma subcapitate; 

 ovules 1 in each ovary-cavity. Drupe fleshy, grooved, containing 2 cartilag- 

 inous, 1-seeded pyrenes. [Greek, a shoot or off-shoot.] Only the following 

 species are known. Type species: Ernodea littoralis Sw. 



Calyx-lobes nearly as long as the frifit or longer. 



Leaves lanceolate to elliptic, oblanceolate or oblong-lanceo- 

 late, 5-10 mm. wide. 

 Corolla white to pink ; leaves relatively broad ; plant 



mostly of coasts. 1. E. littoralis. 



Corolla red to scarlet ; leaves relatively narrow ; plant 



mostly of pine-lands. 2. E. angnsta. 



Leaves narrowly linear, 1-3 mm. wide. 3. E. Colt ri. 



Calyx-lobes much shorter than the fruit. 



Leaves oblong-lanceolate, 6-8 mm. wide. 4. E. Millspauf/hii. 



Leaves narrowly linear to linear-oblanceolate, 1-3 mm. wide. 



Leaves bristle-tipped ; calyx-lobes half as long as the fruit. 5. E. Taylori. 

 Leaves merely mucronate ; calyx-lobes one-third as long 



as the fruit. 6. E. Xashii. 



1. Ernodea littoralis Sw. Prodr. 29. 1788. 



A glabrous or glandular-puberulent shrub, 1-16 dm. high, erect, or nearly 

 or quite prostrate, the branches 4-angled, usually densely leafy. Leaves 3-5- 

 nerved, shining, somewhat fleshy, oblong, elliptic, linear-oblong or oblanceolate, 

 2-3.5 cm. long, 4-10 mm. wide; entire or glandular-serrulate; stipules 1.5-2 

 mm. long; calyx-lobes linear-lanceolate, longer than the tube; corolla white 

 or pink, its tube 1-1.5 cm. long; fruit subglobose, yellow, 4-6 mm. in diameter, 

 about as long as or somewhat shorter than the calyx-lobes. 



Coastal rocks and sands within the influence of ocean spray, throughout the 

 archipelago from Great Bahama, Abaco and Andros to Mariguana and Inagua : 

 Florida ; Cuba to Porto Rico and Anegada ; St. Croix ; Guadeloupe ; Jamaica. Races 

 differ in habit, pubescence, size and width of leaves. Common Ernodea. 



2. Emodea angusta Small, Bull. N. Y. Bot. Gard. 3: 438. 1905. 



Similar to prostrate races of E. littoralis, glabrous or nearly so. Leaves 

 linear, coriaceous, 2-4 cm. long, 1.5-6 mm. wide; calyx-lobes linear -lanceolate, 

 acute, about one-half as long as the corolla-tube; corolla mostly pink or red to 

 scarlet, its tube 8-10 mm. long; fruit oval, 5-6 mm. long. 



Coastal pine-lands of Garden Cay, Great Bahama, Andros, New Providence : 

 Florida. Pineland Ernodea. 



3. Ernodea Cokeri Britton; Coker in Shattuek, The Bahama Islands 264. 



1905. 



Stems very slender, trailing, branched, finely pubescent, 3-9 dm. long. 

 Leaves narrowly linear, 2-3 cm. long, 1-3 mm. wide, acute, rough-pubescent, 

 1-nerved. narrowed at the base into short petioles; stipules about 2 mm. long; 

 fruit globose-obovoid, about 4 mm. long; calyx-lobes subulate, 6-7 mm. long; 

 fruit oval, about 5 mm. long. 



Trailing on sand dunes and in scrub-lands of Abaco, Great Bahama and Andros. 

 Endemic. Coker's Ernodea.
