56 ERYTHEA. 



Heliotropium curassavicum L. Steamboat Lake, 1896 

 (2,063). In this we have another example of a plant of very wide 

 range but peculiar habitat. Never found, I think, except in 

 strongly saline soil. 



Dodecatheon Jeffreyi Moore. Evanston (3,012). Reported 

 now from this state for the first time. 



Asclepias cryptoceras Watson. This, the handsomest of 

 milkweeds, continues to be found at long intervals in this state, the 

 state from which it was originally described. It was found in 

 great abundance in the Platte River bluffs near Fort Steele, in full 

 blossom, June 5 (3,132). 



Plantago Tweedyi Gray. To find so rare a plant as this in 

 great abundance was an unusual pleasure. In 1895 three plants 

 were secured in the Medicine- Bow Mountains, but in 1897 it was 

 found in abundance at Battle Lake, in the Sierra Madre Mountains. 

 It inhabits moist, grassy places in the sub-alpine region (4,158). 



Eriogonum acaule Nutt. In all my collecting in the state I 

 have but once found this csespitose form, which that time nearly 

 covered a gravelly, stony ridge on the Laramie Plains (1,279). 



Eriogonum andinum Nutt. This species, for some time sup- 

 pressed, I think, should be restored to specific rank. Often valid 

 species are suppressed, because specimens sent out under that name 

 do not represent either the type nor its description. This, in my 

 judgment, is why E. casspitosum Nutt. has been allowed to swallow 

 up this good species, of which excellent specimens have now been 

 secured; Evanston (2,956). 



Eriogonum effusum Nutt. Of the rarity of this outside of 

 Wyoming I am unable to. speak but with us it has been met with 

 only in the saline hills on the southern border of the Red Desert; 

 Salt Wells Creek (3,753). 



Polygonum Kelloggii Greene. A small form of the higher 

 mountains, secured for the first time the past season; Battle-Lake 

 (4,161). 



Salix Barrattiana Hook. Prof. W. W. Rowlee, who has 

 kindly named my willows of the season of 1897, pronounces this 

 one of the great finds of the year. He cites Mr. Bebb's discussion
