The following are descriptions of species n^t given in tlie 5th edi- 

 tion of Gray's Manual. 



Amokpha microphylla, Pursh. — Nearly smooth, dwarf; leaves with very 

 short petioles, obtuse at both ends; spikes short, solitary ; calyx nearly naked, 

 pedicellate, teeth all very acu^jiate;ifcyimes 1-seeded. (.4. nami, Nutt.) 



On the banks of the Missouri." Fronrl to 2 feet high; flowers purple 



and fragrant. A very elegant little sluub. FursJi\s Fl. Amer. Bep., II, i66. 



This compact little shrub is al)undant on the dry prairies of north- 

 western Iowa. It flowers in May, and not in July and August as 

 stated by Pursh. The leaflets are ol^long, conspicuously punctate, 

 iind in 10-20 pairs. 



Heli.anthus Maximilian!, Schvad. — Stem strigose-scabrous, branched; 

 leaves alternate (those of the branches sometimes opposite), lanceolate, en- 

 lire or nearly so, tapering to each end, acuminate, very scabrous and often 

 canescent-strigose on both sides, the lower petioled; scales of the involucre 

 lanceolate-subulate, much attenuate, strigose-canescent; pappus of two lan- 



ceoli^e slightly fringed chatiy scales. Prairies. Missouri, Texas. Torrey 



and Gr<n/s Ft N. Am., IF 325. 



In Meehan's "Native Flowers and Ferns of the United States," 

 where this species is finely figured, the rajige is said to be "probablv 

 confined to the hot and dry regions extending west of the Mississip- 

 pi," and it is stated that "Lawrence, Kansas, seems to he about its 

 northern boundary." It is, however, plentiful in PJmmett County 

 of this state, fully 300 miles further northward.
