240 ART. 19. — y,. HAYATA : 



As a complete description of the present species was not 

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

 of tlie plant. It is perhaps the smallest species of Brach i/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.
