212 Class XIII. Order I. 



Raceme oblong ; petals equal to the stamens, trun- 

 cate ; pedicels of the fruit as large as the peduncle. 



Syn. JlcfAEA S PIC AT A, (3, ALBA. MX. 



ACTAEA AMERICANA, #, ALBA. Pitrsh. 



AcTAEA PACHTPODA. Elliott. 



Stem and leaves like the preceding, but somewhat larger and 

 smoother. Raceme oblong, twice the length and half the 

 breadth of the preceding ; the pedicels being shorter and thick- 

 er. Calyx leaves four, white, oblong, concave, caducous. Pe- 

 tals four to eight, as long as the stamens, white, oval, unguicu- 

 lated, dilated upwards, and truncated. Stamens white, as long 

 as the petals, fiilaments as in the last but shorter, anthers heart 

 shaped, obtuse, white or yellowish. Germ and stigma as in the 

 preceding. Berries milk-white, tipt with red, smaller and about 

 eight seeded, on short, red, incrassated pedicels as large as the 

 common peduncle. Woods. May. A week or two later than 

 the foregoing. Perennial. 



First published as a distinct species, in my name, in Eaton's 

 Manual of Botany, afterward by Mr. Elliott under another name. 

 It is remarkably distinct in its truncated petals, large pedicels, 

 and white, few seeded fruit. The herbage of these two species 

 and of A. spicata of Europe is precisely similar. 



214. CISTUS. 



Subgenus HELIANTHEMUM. Capsule one celled ; septa in 

 the middle of the valves. 



CISTUS CANADENSIS. L. Canadian Cistus. 



Herbaceous, without stipules ; leaves alternate, lan- 

 ceolate, stem ascending. L. 



HELIANTHEMUM CANADENSE. Mich. 



Stem slender, downy, hardly a foot high. Leaves small, near- 

 ly sessile, lanceolate, obtuse, downy, white underneath. Flow- 

 ers lateral, solitary, yellow. Stamens inclined to the upper side. 

 Petals very tender and deciduous ; after they have fallen, the 

 plant has the appearance of Lechea major, for which it has been 

 mistaken. Sandy pastures and hills. June. Perennial. 



At the beginning of frosts, the bark cracks and rolls backward.
