the 3 to I ratio of Mendel's laws, where the expectation would be 107 

 to 36. (See p. 83.) 



Abnormal Dendrohium Wardianum. — Mr. Chittenden showed an 

 abnormal flower of D. Wardianum from Wisley, which Mr. Worsdell 

 examined and reported upon as follows : — 



*' Dimerous flower ; two lateral sepals fused into one, which occupies 

 place of labellum, causing the latter to disappear. Lateral petals 

 displaced into a position at right angles to the fore and aft sepals. 

 Column normal." 



Gall on Daphne Mezereum. — Mr. W. E. Ledger showed a shoot of 

 Daphne Mezereum with numerous gall-like excrescences at the bases 

 of the lateral shoots. Dr. Rendle took them for further examination. 



Albino Seedlings of Crinum Moorei. — Mr. H. W. B. Bradley, of 

 Sydney, N.S. Wales, sent two dark and two white seeds of Crinum 

 Moorei. He stated that the latter, if sown at once, ** will develop 

 ivory-white fohage, but seem to have so Httle vitality that they die 

 out at the end of the first season. . . . Every year a few albino seeds 

 come without any apparent reason. Generally speaking, all the 

 seeds in a fruit are either albino or normal. Last year, in the same 

 fruit, I had two seeds, one normal, the other albino. Both grew. 

 The normal seed developed a normal plant, with green foliage, which 

 is still alive ; the albino seed an albino plant, now dead. This year 

 seeding of Moorei has not been at all free, and I have nearly, if not 

 quite, as many albino as normal seeds ; last season there were very 

 few albinos. 



" In 1912 we had very little rain until March, and we then had a 

 superabundance of rain until August, then no rain to be of any service 

 until after Crinum Moorei had finished flowering. . . . The season 

 immediately preceding the flowering in 1913 and 1914 was very similar 

 and could have had no effect on the matter, as there were very few 

 albinos in 1913 and more than usual in 1914." 



Cuscuta on Ramondia, — ^The manager of the Burton Hardy Plant 

 Nurseries, Christchurch, sent a plant of Ramondia pyrenaica, with a 

 Cuscuta on its foliage, not identifiable further, however, on account 

 of the absence of flowers.
