 AmerUnnn^). 



Var. albiHdrus, Gray. (T. 4 /ncnViJinis, Hook.) Much 

 like the type but usually lower, more slender: Ifts. 

 usually 5: fls. pale or white; petals nearly equaling the 

 stamens. Mountain tops, Colo., northward and west- 

 ward. 



acailis, Lindl. Plant only 3 or 4 in. high: Ivs. as in 

 the above, or only 5-parted: lis. leraon-yellow, spreading, 

 on stems hardly reaching from the ground; sepals 9, 

 nearly lanceolate, acute, sometimes toothed; petals 

 spatulate, shorter than the stamens. Northern India.

EuropSeus, Linn. {T. globdsus, Lam.). Stems erect, 

 35 in. or more high, often branching; lower Ivs, petioled, 

 others sessile; Ifts. only 5-parted, lobed, cleft and 

 toothed, those of the root-leaves on short petioles; fls. 

 of a lemon - yellow color, solitary or in twos, 1-2 in. 

 across, globular in form; sepals 10-15, ovate: petals

 more finely lobed and cleft, fls. a rich orange color with

 soms of this are well suited for cut-flower purposes. 

 The plants thrive best and produce richest colors if 

 partially exposed to the sun. T. giganteus, found in 

 garden lists, is a very tall form of this species. T. 

 Japdnicus, Hort., with large orange fls. in early spring, 

 is by some referred to this species. k. c. Davis.
