Miss Eastwood in connection with the original description being probably 

 N. pedunadata Dougl. This opinion was ventured in my revision, though 

 at the time that was written the Lower California locality seemed to be far

 south of the Santa Inez Mts, Since then, however, I have found the species 

 at Witch Creek, San Diego County, so that it may easily range into Lower 



California. — Hai^ley P. Chandler.

 alous conditions were obsen^ed {fig. i). 

 In one case, by two successive branch- 

 ings, one sporangiophore bore three 

 normal sporangia. In the other case, 

 by a single dichotomous branching, two 

 sporangia were developed. — LeRoy H.

 was of the most sluggish character. The plants, when full grown, were 

 rather crowded together by the arrangement of the pots, and whether this
