in diameter: style filiform, slightly thickened under the stigma: 

 berry ellipsoid, often broadly so, mostly 8-10 mm. long, red: 

 seeds usually solitary, reniform. 



On limestone, hammock on the southern side of Arch Creek 

 north and south of the natural bridge, Florida. Types, for 

 flowers, Small cf Simpson, May 12, 191 7, for fruit, Simpson, 

 August 8, 1917, both in herb. New York Botanical Garden. 



Anamomis Simpsonii differs from A. dicrana in the larger 

 flowers, the several-flowered cymes, and the very numerous 

 stamens. The following key will serve to differentiate the two 

 species : 



Corolla less than i cm. wide; petals 2.5-3.5 mm. long; stamens 



mostly 30-40; cymes few-flowered. i. A. dicrana. 



Corolla over i cm. wide; petals 4.5-6 mm. long; stamens 



mostly 60-70; cymes several-flowered. 2. A. Simpsonii. 



The known geographical distribution is: Arch Creek Ham- 

 mock, small key west of Royal Palm Hammock, and hammocks 

 on the eastern end of Long Key, Everglades. It is to be expected 

 in other hammocks of the Everglade Keys. 



The other closely related species, Anamomis dicrana, grows 

 in an entirely different part of Florida. It occurs along the 

 eastern .coast from about Mosquito Inlet to Cape Canaveral, 

 and on the western coast from the Caloosahatchee River to 

 Cape Romano. 



Rather fragmentary specimens of an Anamomis were collected 

 on Key West many years ago. These have been referred to 

 A. dicrana, but that disposition of them now appears doubtfully 

 correct. The rediscovery of Anamomis on Key West is ex- 

 tremely desirable for the proper disposition of that plant. If it 

 has been exterminated on Key West, it may still come to light 

 on some of the neighboring keys. 



Two additional species, Anamomis longipes and A. bahamensis, 

 are known from the limestone pinelands of the Everglade Keys 

 and of the lower Florida Keys. Thus we can now definitely 

 record four species of Anamomis from Florida, two of which also 

 grow in the West Indies.
