than the filaments: pistillate flowers usually 2 together, sessile 

 in an involucre of several acute pubescent bracts; sepals ovate 

 or elliptic, 1.5-2 mm. long, obtuse, shorter than the campanulate 

 hypanthium: drupe globular, 9-12 mm. in diameter, very 

 fleshy, black under a bloom: stone oval or nearly so, 8-10 mm. 

 long, with prominent rounded ribs. 



Pineland swamps, Apalachicola River delta, Fla. The type 

 specimens, in the herbarium of The New York Botanical Garden 

 were collected by the writer in a swamp north of Port St. Joe, 

 Florida, April 24, 1924, ii2jj for flowers, and in swamps near 

 Port St. Joe, November 27, 1923, lopQS for fruit. 



The habit, an intricately branched stem with numerous 

 branchlets, and the myriad globular drupes distinguish Nyssa 

 ursina from N. hiflora. In addition the small coriaceous narrow 

 leaf-blades are not duplicated in any of our other species. 



The specific name refers to the fact that the bears eat large 

 quantities of the fruit in the fall and winter seasons. 



A NEW CHAMAESYCE FROM FLORIDA 



John K. Small 



The oolite limestone of tropical Florida — both the Miami and 

 the Key West — harbors several endemic spurges of the genus 

 Chamaesyce. Some, in habit resemble small kinds of thyme 

 clinging closely to the rocks, others are merely diffuse, and still 

 others are broom-like. All these kinds rejoice in the pinelands 

 and shun the hammocks. It seems necessary to add another 

 species, related to Chamaesyce brachypoda, to the endemic flora 

 of the Everglade Keys. 



Chamaesyce Mosieri Small sp. nov. Plant with several 

 prostrate wiry, dark, partly shining stems or branches from the 

 top of a woody perennial root, the branchlets wiry, villous- 

 hirsutulous, leafy, irregular: leaves opposite; blades orbicular- 

 reniform to ovate, 4-8 mm. long, acute or obtuse, entire, loosely 

 pubescent, rounded or subcordate at the base; petioles purple or 

 black-purple, pubescent: involucres axillary, campanulate, about 

 I mm. long, sparingly pubescent, purple; glands transversely 

 elliptic, about 0.4 mm. wide; appendages variable, some larger 

 than the gland, others smaller, red or deep-pink, sometimes lobed: 

 capsule about 1.5 mm. long, very broad, sparingly pubescent, 

 the angles rather blunt when dry: seed ovoid, about i mm. long, 

 the faces only slightly uneven.
