9. L. annotinum L. Sp. PL 1 103. 1753 



Prostrate stems a meter or more long, extensively creeping along 

 the surface, very rarely pinnately branching, stiff, rooting, leafy, with 

 frequent aerial branches 15-25 cm. tall, which fork 1-3 times or 

 not at all, producing slender erect branches, which are usually 

 strobile-bearing: leaves 5-8.5 mm. x I — 1.5 mm., in 8 rows, uni- 

 form in shape throughout the plant, longest in the aerial parts 

 where they spread horizontally or are finally somewhat reflexed 

 w r ith upwardly curving apices, lanceolate to linear- lanceolate, 

 broadest at or above the middle, serrulate, acute or pungent : 

 strobiles sessile upon the leafy vertical branches, thick (4 mm. x 

 1—3 cm.), with broadly ovate sporophylls, the latter with erose 

 margins and subulate tips. 



The so-called var. pungcus with stiffer, shorter more erect 

 leaves is a condition not at all confined to mountain forms.

 whorled or scattered bracts and producing one, or frequently 

 3-4 strobiles : leaves linear or somewhat expanded at the mid-
