3. C. brachypoda Small. Branches hirsute or villous-hirsute, with many short 

 internodes: leaf-blades oblong to ovate, hirsute: involucres fully 1 mm. long; 

 appendages much smaller than the red glands, or minute or obsolete: capsules 

 about 2 mm. wide, pubescent: seeds 1 mm. long, brown, obscurely angled.

4. C. pinetorum Small. Branches villous-hirsute often ascending near the tips: 

 leaf-blades reniform or deltoid to orbicular or ovate, conspicuously pubescent: 

 involucres fully 1 mm. long, pubescent: glands green; appendages very narrow, 

 even-edged: capsules fully 2 mm. broad, pubescent: seeds 1 mm. long, trans- 

 versely wrinkled, yellowish. Pinelands. 



5. C. deltoidea (Engelm.) Small. Branches nearly glabrous, closely appressed 

 to the ground: leaf-blades deltoid-ovate or reniform, usually minutely pubes- 

 cent: involucres less than 1 mm. long, glabrous: glands yellow; appendages 

 obsolete: capsules about 2 mm. broad, sparingly pubescent or sometimes gla- 

 brous: seeds less than 1 mm. long, even, yellowish. Pinelands. 



6. C. buxifolia (Lam.) Small. Branches glabrous: leaf -blades ovate to broadly 

 oblong, or those of the lower leaves cuneate: involucres 1.5-2 mm. long, gla- 

 brous: gland-appendages whitish, mere margins or sometimes larger than the 

 glands: capsules 2.5-3 mm. broad, glabrous: seeds 1-1.5 mm. long, obscurely 

 angled. Coastal sand-dunes. F. K. (Ber., Bah., Cuba, Ant.) 



7. C. Porteriana Small. Branches glabrous or pubescent: leaf -blades ovate, 

 oval, oblong, or spatulate: involucres about 1 mm. long, glabrous: gland- 

 appendages reddish, fully as long as the glands, or sometimes narrower: 

 capsules about 2 mm. broad, glabrous: seeds about 1 mm. long, markedly 

 angled. Pinelands. 



8. C. Blodgettii (Engelm.) Small. Branches glabrous or nearly so: leaf -blades 

 oval, oblong, or spatulate: involucres about 1 mm. long, glabrous: gland- 

 appendages white or pinkish, commonly slightly larger than the glands: cap- 

 sules fully 1.5 mm. broad, glabrous: seeds about 1 mm. long. Coastal sand- 

 dunes and low hammocks. F. K. (Ber., Bah., Cuba, Ant.) 



9. C. hyssopifolia (L.) Small. Branches glabrous: leaf -blades linear or nar- 

 rowly linear-lanceolate, sometimes falcate, pale-green or glaucous, shallowly 

 toothed: involucres 1-1.5 mm. long, glabrous: gland-appendages orbicular to 

 reniform, rather conspicuous: capsules about 2 mm. wide, glabrous: seeds red 

 or brown, fully 1 mm. long. Edges of hammocks. (Cuba.) 



10. C. hypericifolia (L.) Small. Branches glabrous or nearly so, the ultimate 

 ones slender: leaf-blades mainly oblong, oblong-lanceolate, or ovate, unequally 

 serrate, usually nearly straight: involucres 1 mm. long or more: gland- 

 appendages obovate to reniform, rather conspicuous: capsules fully 2 mm. 

 wide, glabrous: seeds red or brown, about 1 mm. long. Pinelands. F. K. 

 (Ber., Bah., Cuba, Ant.) 



11. C. brasiliensis (Lam.) Small. Branches glabrous, the ultimate ones fili- 

 form: leaf -blades resembling those of C. hypericifolia: involucres 1 mm. long 

 or less: gland-appendages mostly obovate, rather inconspicuous: capsules 

 usually less than 2 mm. wide: seeds gray, about 1 mm. long. Pinelands. 

 F. K. (Bah., Cuba, Ant.) 



12. C. Tracyi Small. Branches thinly canescent: leaf -blades oblong to slightly 

 broadest above the middle: involucres fully 1 mm. long, sparingly pubescent: 

 gland-appendages minute, unequal and uneven: capsules nearly 2 mm. broad, 

 slightly pubescent all over: seeds less than 1 mm. long. Coastal sand-dunes 

 and pinelands. F. K.
