rather deep-seated and the young tuber had apparently been wedged 

 against the "eyebrow," and by its lateral expansion, and owing to 

 the pressure of other tubers above, had split the parent tuber, having 

 probably entered it at a spot where there was some defect in the 

 old tuber. Its further development had been within the cleft so 

 formed. It should be understood that the old tuber had produced 

 the new tubers in dry store. 



Garden Mints. — A large number of specimens of Mint were brought 

 by members of the Committee from various districts, and one was 

 sent by Mr. Fletcher, of Aldwich Manor, Bognor. They included 

 several forms of Mentha viridis, some of which had a trace of pepper- 

 mint scent and one or two of which were free from it, especially one 

 brought by Mr. Shea from his garden, the hybrid M. X sativa, M. 

 gracilis cardiaca, M. crispa [M. viridis x M. rotundifolia), M. rotundi- 

 folia (called in some places ' Apple Mint '), and M. alopecuroides. 

 The last two appear to be unsuitable for drying, and are perhaps 

 not so full-flavoured as are the forms of M. viridis. 



Berberis with Supplementary Leaflet. — Mr. Fletcher also sent foliage 

 of Berberis Aquifolium with a supplementary small leaflet arising 

 from the midrib of the leaf at about the middle, and on its upper side 

 near the base of one of the ordinary leaflets as though it were a foliose 

 stipule. 



Campanula Hybrids. — Mr. Grove showed seedlings of Campanula 

 ' Norman Grove' (C. Tommasiniana x C. carpatica ' White Star'). 

 Several seedlings had been raised, the result of self-fertilizing the 

 hybrid, and they showed reversion towards both parents. One was 

 a distinct carpatica form with a tinge of colour on the outside of the 

 corolla, and at the other extreme a narrow-tubed (but still campanu- 

 late) blue-flowered form, approaching Tommasiniana in some way, 

 but distinct. 



Dodder on Streptocarpus. — Mr. L. Dawes, of Charlton Lea Gardens, 

 Headington, Oxford, sent leaves of a Streptocarpus on which a species 

 of Cuscuia was flourishing. The parasite was not in flower, and was 

 therefore not identifiable. 



Scientific Committee, August 4, 1915. 



Mr. E. A. Bowles, M.A., F.L.S., F.E.S., in the Chair, with six 

 members present, and Mr. Grove, visitor. 



Leaf-cutting Bee. — Mr. J. Fraser, F.L.S., showed leaves of Labur- 

 num from which pieces had been cut by the leaf-cutting bee for nest- 

 making. 



Campanula Hybrids. — Mr. Grove, of Sutton Coldfield, showed a 

 further series of seedlings from Campanula 'Norman Grove' self- 

 fertilized. They showed a great range of variation between the 

 parents of C. ' Norman Grove ' in colour, stature, habit, and 

 foliage. Mr. Grove had taken great pains to record the parentage and
