CATALOGUE OF CANADIAN PLANTS. 225 



VMi'ieties. It has been reported from Nova Scotia (though doubtfully), 

 and from western Ontario by Maclagan, but we have never seen 

 an eastern specimen. Our western specimens approach A. p^^nicu- 

 latus but differ in having the involucral bracts ciliate, the heads larger 

 and the leaves wider. 



(104-1.) A. junceus, Ait. 



A. laxus, var. borealis, Mac'oun's Cat., No. 850. ^ 



A. borealis, Provancher, Fl. Canad. I., 308. 



A. laxifolius, Nees. Hook. Fl. II., 10. Macoun's Cat., No. 840. 



A. laxifoliufi, var. borcalix, Terr. & Gi'aj' Fl. II., 138. 



A. bdUditioms, Hook. Fl. II., 11. 



This species, as I understand it, grows in our cold bogs and wet mea- 

 dows and is generally in flower in the latter part of July. It extends 

 from, the eastern provinces to the Eocky Mountains, and is not unfrequent 

 on wet boggy places in the prairie region. (Macoun.) Wooded country 

 from Lat. 54°-64^ ; also, Slave Lake. {Richardson.) Fx*om Hudson 

 Bay to the Eocky Mountains in swampy places. {Brmnmond.) Chil- 

 coten Eiver, B.C. (Dawson.) 



(1045.) A. sestivus, Ait. 



Dr. Gi-ray says this species is indigenous in British America, but I 

 have no means of separating it from the preceding which very likely 

 includes forms of it. This is named " Labrador star-Avort," and is said 

 to flower by the middle of June. Very likely both this and the pre- 

 ceding are the same. 



(1046.) A. Novi-Belgii, Linn. 



A. longifolius, Lam. in part for eastern specimens. 



We have no specimens of this species from the eastern provinces 

 and are not certain of its occurrence there, but as Dr. Gray states 

 it has been confounded with ^4. longifolius it will, in all probability, be 

 found within their limits. The western form, which may be the 

 A. asper, Lindl., referred to on page 10, Hook. Fl. Vol. XL, was obtained 

 at Morley in the valley of Bow Elver. (Alacoun.) 



(104t.) A. tardiflorus, Linn. 



A. Cornuti, Nees. Hook. Fl. II., 9. 



A. patulus, Lam. Terr. & Gray Fl. II., 148. 



Native of Lower Canada, (Dr. Gray.) Frequent along the Gaspd 

 coast, but hitherto referred to A. longifolius. Eather common on Anti- 

 costi, especially at the mouth of Jupiter Eiver. (Macoun.) Possibly 

 mistaken in Nova Scotia and New Brunswick for A. longifolius.
