with an ovate bract; calyx 2 lines long with short and acute, teeth ■ 

 flowers 4 to 5 lines long, dark purple in bud, becoming orange • puds 

 two or three seeded, slightly incurved. 



This plant is nearest H.jiuicea, but differs in its long pednneled um- 

 bels, acute calyx teeth, etc. We take pleasure in dedicating this new- 

 species to Dr, Sereno Watson. 



637. H. Palmeri n. sp. 



Seemingly nearest H. prostrata, Nutt. Annual, 1 to 2 feet high, 

 branching, pubescent when young, becoming nearly glabrous: leaflets, 

 three to seven (mostly five), 4 to lines long, on a somewhat winged 

 rhachis, ovate to oblong, obtuse ; the capitate umbels many-flowered 

 (sometimes one or two), with ovate bract, on sleuder peduncles (I to 1.', 

 inches long); calyx pubescent even in fruit; teeth minute; flowers, 2 to 

 3 lines long, "scarlet;" style glabrous; pods two-seeded, much coiled. 



Differs from H.prostrata in its more erect habit, larger, less crowded 

 leaflets, longer peduncles, and coiled pods, etc.

Stems 1 to 20 inches high, erector prostrate, the petals often redden- 

 ing on drying, and having a black spot at base, as in (E. bistorta. 

 Later on, a peculiar form was collected, acaulescent or with short
