^8 NOTES AND NEWS 



cular tissue may easily be seen within ; its cortical tissue con- 

 sists of enlarged cells, especially in its outer zones. The bulb 

 gradually elongates till it attains a length of 8 or lo mm., 

 at which time the stem, leafless of course, has grown to a 

 length of 60 mm. or somewhat over. After this size has 

 been attained, the rootlet and bulb gradually give up their 

 contents to the elongating stem. The suggestion lies at 

 hand that the organ described is a special adaptation to the 

 conditions of the desert, which would be interesting, if true. 

 The suggestion has however this merit that it would be 

 worth while to make a comparative study of the germination 

 of a number of species of Cuscuta, both from the region 

 where they are most abundant, and where the conditions for 

 germination are not so perilous and from other desert regions.

The twenty-fifth anniversary of the work of Professor 

 Sergius Nawaschine, University of Kief, Russia, was cele- 

 brated March 3, by his students and friends. Congratula- 

 tory letters were received from scientists all over the world. 

 Professor Nawaschine is best known in America for his 

 morphological and cytological studies on the higher plants. 



Dr. J. N. Rose, Assistant Curator of the U. S. National 

 Museum, will leave Washington late in March for an ex- 

 tended tour of study of cacti in the southwest. He will 

 spend the month of April at the Desert Laboratory at Tuc- 

 son.
