Rydberg: Studies on the Rocky Mountain flora 481 



Macoun; also a specimen from Hooker's herbarium without date, 

 probably collected by Richardson, at Carlton House. (Both in 

 herb. Columbia University.) 



Cryptanthe flexiiosa A. Nelson is, I think, the same as C. 

 calycosa (A. Gray) Rydb., and C. murkulata montana A. Nels. 

 should be referred to C. amhigua (A. Gray) Greene, and C. Hill- 

 mani A. Nels. to C. Watsoni (A. Gray) Greene. C. flaccida (A. 

 Gray) Greene has been collected in Idaho; C. reciirvata Coville, in 

 Utah and Colorado. 



Mertensia coriacea A. Nels. is the same as M. lanceolata 

 Pursh. Professor Nelson gives the range of M. lanceolata as 

 Colorado and Wyoming. The type came from western Montana. 

 M. perplexa is not the same as M. coriacea, as stated by Professor 

 Nelson, but belongs to the M. alpina group with subsessile anthers. 



Anchusa officinalis L. and Asperugo procumhens L. have been 

 collected in Colorado; Plagiohotrys arizoniciis (Gray) Greene in 

 Utah; P. tenellus A. Gray in Idaho; Cynoglossum officinale L. in 

 Wyoming and Montana; Eremocarya muricata Rydb. in Utah; 

 Lithospermiim arvense L. in Utah; Mertensia brachycalyx Piper in 

 Idaho; M. pulchella Piper, M. nutans Howell, and M. longiflora 

 Greene in Idaho and Montana; Amsinckia hispidissima Suksd., 

 A. retrorsa Suksd. and A. micrantha Suksd. have been collected in 

 Idaho. 



Pectocarya miser A. Nels. I can not distinguish from P. peni- 

 cillata (H. & A.) A. DC. Eddya hispidissima Torrey has been 

 collected in Utah. 



VERBENACEAE 



Verbena remota Benth. was collected in southeastern Utah in 

 191 1 by Professor Garrett and myself. Verbena bipinnatifida 

 Nutt. is very rare in the region and V. canadensis (L.) Britton does 

 not occur at all. The range given in Coulter & Nelson's New 

 Manual is erroneous. The group is represented in the Rocky 

 Mountains by V. ambrosifolia Rydb., V. Gooddingii Briq., and 

 V. ciliata Benth. 



LAMIACEAE 



Lamium amplexicaide L. has been collected in Colorado; 

 Micromeria Douglasii Benth. and Trichostoma ohlongnm Benth., 

 in Idaho.
