inlet of Lac Panache, District of Algoma. I cut specimens, this year, 

 which measured 8 feet 6 inches in length and bore leaves 17 inches 

 long. The stem was hollow and jointed like sugar cane ; the joints 

 were from two to eight inches in length. Towards the top the long, 

 narrow, pointed leaves grew out of one side and the whole was sur- 

 mounted by a tuft of purplish, oat-like seeds. On one specimen I 

 noticed three tiers of aerial roots radiating from the first three joints 

 above the root, there being one and a half inches between the first and 

 second tiers, and four inches between the second and third. There 

 were six roots radiating from each joint. It is certainly a very hand- 

 some plant and some of the ripe plumes were very silky and pretty. J. F. 



This grass has also been collected by Rev. G. Bousfield, about three 

 miles from Billings Bridge. The nearest point to Ottawa at which it 

 had been previously collected was Casselman (30 miles). 



Cystopus on Capsella. It is a common habit now-a-days to 

 look upon all fungi as injurious plants. A walk through a neglected 

 garden at the present time will, however, discover one member of this 

 large family doing good work for the cultivator. Shepheid's purse 

 {Capsella bursa parton's, Moench) is being freely destroyed by a form of 

 mildew known as Cystopus Candidas (PJ Lev. Unfortunately, how- 

 ever, this disease does not confine its attentions to Shepherd's purse, 

 but is frequently found on other members of the mustard family and is 

 also a common enemy of grasses when grown in badly drained soils. J.C. 



-Affinity between Stock and Scion. In the development of 

 new varieties the exact limit oi possible hybridization is yet undefined ; 

 the same is true also when applied to the multiplication of the individual 

 by the art of budding and grafting. There are in both instances in 

 the one the science, in the other the art many gradations between 

 failure and complete success. 



In hybridizing plants, not nearly related, the pulp or receptacle of 

 the fruit (seed) frequently or usually developes, but may, or often con- 

 tains only infertile seed. Again, in the case of uniting the wood of two 

 widely varying plants by grafting or budding, while the operation may 

 appear to be entirely successful the first season, as judged by the growth 

 of the scion, yet examination frequently reveals the fact that no real 

 union of fibre has really taken place between the stock and the scion.
