Few men have been more indefatigable in the study of any tribe of 
: plants than Dr. Spring has been in that of the Lycopodiacee, and the 
.. . result, as shown in the present publication, is alike honourable to him-

2. SELAGINELLA.—Antheridiis unilocularibus. Oophoridiis 3-4- 
coccis.

_ 4. Pstnorum.—Antheridiis trilocularibus. Oophoridiis nullis. 
_ Lxcoroprux embraces 107 species ; SELAGINELLA, 209; TMESIP- 
TERIS, 2; PsrLoTUM, 4. An excellent “ Morphologie et Organographie 
_ des LYCOPODIACÉES,” concludes the volume of 358 pages.
