'G. germanica, Willd. A small-flowered form abundant in a chalk pit at North Sydmonton, Hampshire, this year, 21st September, 1896. The plants varied considerably in character, and in several cases there was difficulty in distinguishing them from robust forms of G. Amarella, Linn. - A. B. Jackson. "I could not refer these specimens either to G. germanica or G. Amarella, and as certain features suggested a hybrid origin I sent samples to Dr. von Wettstein, who, after closely examining the plant, agrees in thinking it a hybrid between the two above species. He arrives at this conclusion because:- '1. It is completely intermediate, morphologically, between the two species named. 2. The sterility of the pollen. I could, however, only examine one flower, as the others were going to seed. This one contained 48% of abortive pollen grains. 3. The small number of fully developed seeds. I examined three capsules, of which one contained 56%, the second 97%, and the third 88% of evidently abortive seeds.' Dr. Wettstein adds that for a complete determination it would be necessary to know whether the plant grows in company with its putative parents. Mr. Jackson has promised to investigate this point, but I may mention that I have seen G. germanica, Willd., from the locality. (See 'Report' for 1892, p.379.'" - W. H. Beeby.' (?
