Time has not permitted the examination of the amount of trans- 
piration accomplished by the leaves of the whole number of summer 
deciduous shrubs which occur in this region. Two of the most impor- 
tant species are Calycotome villosa Link and Cyttsus scopartus Link. 
The former ot these gave on two successive days, with different speci- 
mens each day 2.6 times and 3.3 times as much loss from leafy as from 
leafless branches. The latter on different days and with different 
specimens gave 3.5 times and 3.1 times. These experiments were 
conducted exactly like those with Spartium. 
My conclusions may be briefly summarized as follows: 
1. In the three species examined, during the leafy season, the 
relative power of transpiration of the leaves as compared with that of 
the cortex is much greater, for equal areas. 
2. During the leafy season, the total transpiration due to leaves 
may be more than three times as great as that due to cortex. 
3. Photosynthetic work due to leaves is probably much greater 
during the leafy season and perhaps for the entire year than that due 
to cortex. 
4. Leafless individuals of Spartium grow but little at any season.—

GEASTER LEPTOSPERMUS: A CORRECTION. 
In the number of the BoTaNICAL GAZETTE for October last, page 
306, in the technical description of Geaster loptospermus Atk. & 
Coker, n. sp., occurs a typographical error in lines 14 and 22, thew 
- being used in place of mm. The measurements in these lines should 
read 3-4.5™" and 2.5-3.5™". In the general text the measurements 
were properly given, the error occurring only in the technical descrip- 
tion.— Gro. F. Atkinson, Cornell University.
