472 MINNESOTA BOTANFCAL STUDIES 



Uvular ia pcrfoliata L. 



Apparently docs not occur; all the Minnesota specimens in the Uni- 

 versity Hcrliarinm lahelled I'. pirfoHnta are IJ. grandiflora J. E. 

 Smith. 



Allium Schoctwprasum L. var. sibiricnm (L.) Hartm. 

 No specimens ; doubtful whether it occurs. 

 • Allium ccrnuum Roth. 



Apparently does not occur ; all specimens in the University Her- 

 barium labelled A. cernuuni are A. stcllatum Ker. 



I.ilium stiperbum L. 



This species has been reported from various parts of the state, but 

 it seems that all these collections will have to be referred to L. 

 canadensi- L. The lily common in our moist meadows and rich 

 grounds seems to combine those characters utilized in the manuals 

 and floras for separating L. supcrbiim from L. canadense. The 

 leaves have the rough margins and nerves of L. canadense, but the 

 orange-colored flowers with the strongly reflexed perianth segments 

 of L. superbuni. Occasionally forms occur in which the nerves are 

 almost smooth. The plant produces a rhizome about 7-10 cm. long, 

 which by the end of July has developed a distinct bulb at the end 

 with numerous close-set yellowi^h scales.* 



Camassia esculenta (Ker) Robinson. 



Reported from soutliern part of the state in Upham's Catalogue; 

 no specimens ; occurrence very doubtful. 



Streptopiis roseus Michx. 



All previous reports of this species should he referred to S. lougipes 

 Fernald. 



Medeola virginiana L. 



No specimens ; probably does not occur. 



Trillium sessile L. 



No specimens ; probably does not occur. 



Trillium reciirvatum Beck. 



No specimens : probably does not occur. 



Trillium erectum L. 



All reports of this species are to be referred to T. declinatum (Gray) 

 Gleason. 



Aletris farinosa L. 



Reported in Lapham's Catalogue; no specimens; probably doos not 

 occur. 



Smilax ecirrhata (Engelm.) Wats. 



Confused with young specimens of S. herbacea L. ; does not occur. 



•Since this paragraph was written, O. A. Farwell has described two new species of 

 Lilixim from Michigan, L. michiganense and L. pcramoenum (Bull. Torr. Bot. Clu" 

 42:351). All of the Minnesota specimens which have been called L. supcrbum and L. 

 canadense appear to belong to these new species. To the present authors it appears 

 from Mr. Farwell's descriptions, and the examination of many Minnesota specimens that 

 the two proposed species are doubtfully distinct from one another.
