MONTANA BOTANY NOTES 33 



Heuchera Hallii var. grossulariifolia (Rydberg Fl. Mont. 196 as species) 

 Ryan's Lake and Mt. Haggin, both bordering on Deer Lodge Valley. Also at 

 Ketchum, Idaho (Mrs. Brodhead). 



Heuchera Williamsii Eaton. This both Greene and Rydberg put into 

 Tellima (Lithophragma) because it has a turbinate calyx anu racemose 

 habit, while they ignore the far more important heucheriod leaves, roots 

 and five stamens, which clearly place it in Heuchera. Lima, probably not 

 in our region. 



Mitella trifida Graham. Bigfork, Alta, McDonald Lake in the Mission 

 Mountain.s. Al.^o Missoula by Elrod and MacDougal. 



• Mitella trifida var. stauropetala (Piper Erythea 7 161 as species.) Coeur 

 d'Alene Lake, Deer Lake in Southern Idaho. Baker's number 263 from Mt. 

 Hesperus, Colorado, is the same. This is a form with long and filiform 

 lobes. Greene (Pitt. 1 32), Rydberg (Fl. Mont.), and Piper (Erythea 7), have 

 split this species up into several unwarranted species, based on the develop- 

 ment of lobes in the petals, but there is every gradation in length and width 

 from rudimentary to long and filiform lobes. Greene's species is M. diversi- 

 folia, Rydberg's M. violacea, and Piper's M. stauropetala and stenopetala 

 and var. Parryi. 



Mitella Brewer! Gray. Common on MacDougal Peak. 



Mitella pentandra Hook. Common on all the high peaks from Alta north- 

 ward. 



Mitella nuda L. Frequent in dark woods from McDonald Lake in the 

 Mission Mountains to the Boundary. 



Tellima tenella (Nutt.) Walp. Missoula (Elrod); Columbia Falls (Wil- 

 liams). 



Tellima glabra (Nutt.) Steud. Bigfork (Elrod); with short pedicels. 

 Columbia Falls (Williams) with pedicels over half an inch long. 



Tellima parviflora (Nutt.) Hook. Missoula (Elrod and MacDougal), 

 Columbia Falls (Williams). 



Tiarella trifoliata L. Bigfork, very rare. It was sought constantly 

 throughout the region from Alta to Blackfoot Glacier this year but none 

 could be found, while T. unifoliata was everywhere. 



Parnassia parviflora DC. Swan Lake. All forms reported as P. palustris 

 from this region are of this species. The Dissection of the stamlnodia 

 amounts to but little. 



Ribes Hudsonianum Rich., R. petiolare Douglas. There is no permanency 

 in the characters of R. petiolare. Its leaves are normally much larger and 

 longer petioled, but all sorts of intergrades occur, Alta, Hamilton, Anaconda 

 and Mt. Haggin. 



Ribes Howellii Greene. Its character of drooping short and few flowered 

 racemes seems to hold, the others do not. St. Ignatius Mission in deep and 

 dafk willow swamps. 



Ribes viscosissimum Pursh. Frequent in all the mountains from Alta 

 northward. 



Ribes cereum Dougl. Common in all the mountains from Alta northward. 



Ribes lacustre (Pers.) Poir. Frequent at all elevations but most common 

 at low elevations from Alta northward to the Boundary. The typical form 

 has black fruit, slender racemes, and only lobed leaves. 



Ribes lacustre var. parvulum Gray. This has leaves lobed nearly to the 

 base and .smooth, rarely over an inch wide, hardly deserves varietal rank. 

 Hamilton, Anaconda, Alta. 



Ribes lacustre var. lentum Jones, R. lacustre var. molle Gray. This is 

 very pubescent and glutinous all over, with small and much dissected leaves 

 often only half an inch wide. It is strikingly different from the type and 

 grows in alpine places only and usually has red fruit, though not always. 

 The type and var. parvulum have black fruit normally but often red when 

 immature. Alta, Como Peak.
