A New Pawpaw from Florida. — The genus Asimina is 

 confined to eastern North America. It separates naturally into 

 two groups, the one typified by Asimina triloba — the type of 

 the genus — with a geographic range extending from about the 

 latitude of Lake Erie to upper peninsula Florida. The other 

 group is typified by Asimina pygmaea, which together with a 

 half dozen associates has a geographic range covering most of 

 Florida, with an extension into the southeastern corner of 

 Alabama and into southern Georgia. 



While on the last leg of an extensive excursion on which all 

 the species of the second mentioned group were studied in 

 the field we unexpectedly discovered an additional species, which 

 is here named and described: 



V Asimina tetramera Small, sp. nov. Shrub 1-3 m. tall, with 

 irregularly-placed often virgate branches, the bark gray and 

 glabrous, except on the red finely pubescent twigs: leaf-blades 

 spatulate to elliptic-spatulate, 3-13 cm. long, obtuse, bright- 

 green, glabrous and finely reticulate on maturity, sessile: flowers 

 solitary in the axils of the leaves: sepals 4, rhombic-ovate, 

 7-10 mm. long, obtuse or acutish: petals 8, the four outer 

 lanceolate or elliptic-lanceolate, 1.5-2.5 cm. long, obtuse, white 

 above, reddish-purple below the middle, the tour inner rhombic- 

 ovate or rhombic, 9-1 1 mm. long, reddish-purple, obtuse, 

 constricted at the base, stamens numerous, nearly 2 mm. long, 

 the connective ending in an expanded gland-like tip: carpels 

 5-7, the stigma knob-like: fruit ellipsoid or cylindric-ellipsoid, 

 mostly 5-9 cm. long, greenish-yellow: seeds ov^oid-ellipsoid, 15- 

 18 mm. long. — x'\ncient dunes, "scrub," near the estuary of 

 the St. Lucie River, Florida. 



Technically this shrub is related to Asimina pygmaea which 

 is smallest in habit and bears the smallest flowers, and as in 

 the case of its associates the perianth is trimerous. The species 

 just described is one of the tallest in habit, has the smallest 

 flowers now known in the group, and the perianth is tetramerous, 

 as far as it is known. 



Fortunately the shrubs, when we discovered them, were in 

 full flower and ripe fruit. The type specimens collected by the 

 writer near Rio, Florida, July 26, 1924, are now in the herbarium 

 of The New York Botanical Garden.
