 anthers yellow ; ovary glabrous. Fruit short-oblong or slightly obovate, acute and abruptly short-pointed at the apex, rounded at t lie 

 base, red, from 1.3 to 1.4 centimetres long and 1 centimetre in diameter, with a thick skin becoming conspicuously reticulata in drying 

 and thin dry spongy flesh closely adherent to the stone ; stone oval in outline, nearly symmetrical on the two edges, only slightly

Florida : Killarney, Orange Countv, Otto Yesterhmd, March and May, 1889 (type for the flowers) (in herb. Cray) ; high sand 

 hills south of Minneola, Lake County, common in pine woods, R. M. Harper, April 17, 1909 (No. 31 type for the fruit) (in herb. 

 Arnold Arboretum and in herb. Gray). 



Among the species of true Plums (Prunophora) this plant is peculiar in its solitary sessile flowers. Such flowers are not 

 uncommon in Emplectocladus, but with its glabrous ovary and fruit Primus sessiiijtora cannot be united with that section of the 

 genus, which with the other Amygdahv is distinguished by its pubescent fruits. 



Prunus tkxana, Dietr. 



This name should apparently be taken up for the small Texas shrubby Prunus which has usually been called Prunus glandu- 

 losa, Torrey & Gray, this name having been previously applied by Thunberg to > Japanese species whirl, later was confounded 

 with Prunus japonica, Thunberg. The synonymy of this Texas Plum thus becomes,— 

 Prunus tkxana, Dietrich, Syn. PI iii. 45 (1843). 

 Amygdalus glandulosa, Hooker, Icon. iii. t. 288 (1840). 



Prunus glandulosa (Hooker), Torrey & Gray, Fl. N. Am. i. 408 (not Thunberg) (1840). 

 Prunus Hooheri, C. K. Schneider, III. Handb. Laubholzk. i. 597 (1906).
