LYCOPODIACE^E. 



327 



Hab. Sandwich Islands ; frequent on trees and decayed wood, on 

 all the islands of this group visited by us. 



20. Lycopodium nutans, Sp. Nov. (Tab. 46.) 



L. caule rigido erecto clicliotomo; foliis verticillatis divaricatis lanceolato- 

 linearibus integerrimis aeutis margine revolutis; spiels crassis teretibus 

 obtusis dichotomis nutantibus; squamis imbricatis oblongis acuminatis; 

 capsulis reniformibus. 



Hab. Sandwich Islands : high mountains of Oahu, growing on 

 trees; rare. 



Stem erect, rigid, about the thickness of a goosequill, from 14 to 18 

 inches high, twice or thrice dkhotomously branched. Leaves rigid, 

 approximate, verticillate, 4 or 5 in a whorl, the lower ones a little 

 detlexed, those of the branches divaricate, lance-linear, acute, 8 to 10 

 lines long and lh lines broad, the margin revolute and entire, those 

 towards the base of the spike the shortest ; the nerve on the upper 

 side slightly carinate, beneath plane. Spikes 3 to 5 inches in length 

 and about one-fourth of an inch in diameter, stoid, round, nodding, 

 and once or twice dichotomously branched; the branches tapering very 

 gradually towards the apex, which is obtuse. Scales 3 or 4 times 

 longer than the capsules, erect, imbricated, oblong, acuminate. Cap- 

 sules two-valved, of a pale straw-colour, reniform, and entirely con- 

 cealed by the scales. 



This is one of the most robust species of the genus. It is very 

 well distinguished from the preceding by its stouter stem, and its thick 

 and nodding spikes : the leaves on the stems also are more crowded, 

 and the scales of the spikes are of considerably greater length.
