P. flavum, E. L. Greene in Coulter s Hot. Gazette (Indiana, U.S., June 1881), 

 vol. vi. p. 218 ; Gray Synopt. Flora ofN. America, Gamopetalce, p. 412. 



Mr. Greene says of this plant, when describing it in the 

 " Botanical Gazette," " It is hard to establish, and some- 

 what hazardous to propose, new species of Polemonium. 

 The claim for specific rank for this very striking and 

 beautiful plant I base upon the shape and colour of 

 the corolla. No other species but P. confertum shows a 

 corolla whose limb is really funnel-formed, that is not at 

 all spreading ; nor has any other form red-yellow flowers 

 which show no tinges of blue or purple or flesh colour, even 

 in fading. Its nearest ally is P.foUosissimum, while it 

 has more the look of P. earneum." The chief of American 

 botanists, Dr. A. Gray, having admitted the claims of P. 

 flavum to specific rank, Mr. Greene's views are confirmed. 

 I must remark, however, that as cultivated at Kew 

 the corolla-lobes do spread, and show no trace of a tawny 

 red colour. With regard to P. carncum, A. Gray, a native of 

 San Francisco, it agrees with P. flavum in habit, and has 

 a yellow-flowered variety assigned to it by Gray, but it has 

 rounded apices of the corolla-lobes. A third species that 

 much resembles P. flavum is P.incarnatum, A.Gray (Greene's 

 Plants of California, No. 796), but that is more glabrous, 

 has obtuse calyx-lobes, a very large corolla with rounded
