386 Class XXIV. Order I. 



Commonly quoted as a synonym of the preceding, but very 

 distinct. The brandies are always erect, and appear cylindrical 

 from the equality of the leaves, whereas in the former they are 

 spreading and appear flat from the unequal rows of leaves. 

 Spikes in this numerous, in the other most frequently one. 

 Woods, Sudbury.

Leaves scattered, entire, lanceolate, awnless, in 

 eight equal rows ; stems dichotomous, erect, fastigiate ; 

 fruit axillary. 



A dense, leafy species, distinguished from the following by its 

 smaller size and entire leaves, while it resembles it in being des- 

 titute of spikes, the capsules growing in the axils of the leaves. 

 On the highest summit of the White mountains. 



LYCOPODIUM LUCIDULUBI. Mich. Shining Club Moss. 



Stems assurgent with a few longish branches ; leaves 

 spreading, shining, linear-lanceolate, serrate ; fructifi-

Stems nearly erect, simple or dichotomous. Leaves in about 

 eight rows, longer than in any of the preceding species, linear- 

 lanceolate, somewhat xeflexed, distinctly serrate, very acute, 

 polished on both sides. Capsules axillary, semicircular. A small 

 stem bulb is sometimes found occupying the place of a leaf. 

 Shady borders of ponds &c.

Stipe naked ; frond glabrous, radical, three partecl- 

 bipinnate ; segments crenate ; spikes bipinnate. 



A rather small fern with a single frond given off from the 

 stipe near the root. This frond is petioled, more or less com- 

 pound according to the size of the plant, but commonly ternate, 

 the divisions pinnate and pinnatifid. Capsules globular, sessile, 

 in two rows on the branchlets of a bipinnate panicle. Dry pas-
