240 ART. 19.— li. hayata: 



As a complete description of the present species was not 

 previously made, I have taken this occasion to give a full account 

 of the plant. It is perhaps the smallest species of Brachy podium, 

 which species is very remarkable for its terete leaves and its 

 simplest form of an inflorescence reduced into one spicule. The 

 leaves are very slender and they measure but 1 mm. in diameter, 

 and 3 mm. in circumference.
