206 Britton : The genus Ernodea 



ing upward from below the middle, 6 cm. long, i cnh wide, entire- 

 margined ; calyx-lobes a little longer than the fruit. 



Bahamas : Swamp, road to Stopper Hill, Crooked Island 

 {Brace ^.Soy'). This is the only specimen known to me to grow 

 in swampy ground. 



Race §. Leaves relatively thin, linear-oblong, entire-margined ; 

 calyx-lobes very narrow, 1.5 times as long as the fruit. 



St. Croix : Pinetree Bay \A. E. Ricksecker jjj, type). 



Porto Rico : Limestone hills three miles west of Ponce 

 {Ne/Zcr 6243). 



There is no doubt that if plants here included in the typical 

 race could be grown from seed, side by side, additional races to 

 those here defined would be indicated by differences which her- 

 barium specimens do not exhibit. 



The typical race usually grows within the reach of ocean spray, 

 accompanied by distinctively halophytic plants. 



2. Ernodea angusta Small, Bull. N. Y. Bot. 

 Card. 3: 438. 1905 



This pine-barren plant of southern Florida was proposed by 

 Dr. Small as a species distinct from E. littoralis on account of its 

 smaller flowers and narrower leaves. He described the flowers as 

 whitish ; they are pink or red, though the albino condition may, 

 likely enough, exist. My observations do not bear out the origi- 

 nal observation that the flowers are necessarily smaller than those 

 of E. littoralis, and plants of that species sometimes bear leaves as 

 narrow as those of Dr. Small's type specimen, while red-flowered 

 plants existing on the northern Bahama islands, while mostly 

 narrow-leaved, like the type, sometimes bear broader leaves. It 

 is an interesting circumstance that plants conforming to the type 

 in both characters occur throughout the area of Firms caribaea 

 Morelet in South Florida and the northern Bahamas, almostthough 

 not quite to the exclusion of typical E. littoralis, as though the 

 pine-land condition suited E. angusta, considered either as a species 

 or as a race o{ E. littoralis ; this is an ecological feature of extreme 

 interest, especially as there are a number of other species or 

 races which give character to these pine-lands. E. angusta appar- 

 ently extends to the coasts where pine-lands are near by, or where
