1 60 MEMORANDA. 



Hydrangeas. — The plants under experiment were nine in number, all 

 potted in one sort of soil, and all in the same sized pots (6 in.). To eight of 

 those a small quantity of the following substances was given : phosphate of 

 iron, sulphate of iron, alum, caustic potash, phosphate of magnesia, and car- 

 bonate of potash. The plant which received ^ oz. carbonate of potash died, 

 also one which received ^ oz. of phosphate of iron and 3 oz. of alum. The 

 plant in pure soil produced large healthy leaves and a stem 2 feet 6 inches in 

 height, terminated with two large masses of flowers. That in 5 oz. phosphate 

 of iron was 1.5 inches high, with leaves little more than half the usual size, 

 petals considerably smaller but of the same colour, and flowers in great pro- 

 fusion. That in J oz. of phosphate of iron was not different from the last. 

 The plant in -^ oz. of sulphate of iron was 11 inches high, its leaves green 

 and healthy, its petals rather smaller than their usual size, heads dense, and 

 large in proportion to the size of the plant, but no change in their colours. 

 The plant treated with ^ oz. of alum was 9 inches high, had leaves about half 

 their usual size, petals in proportion, which were of a pale blue colour, and 

 numerous branches, all terminated with dense masses of flowers. This plant 

 stood in the conservatory seven weeks in bloom : ^ oz. caustic potash formed 

 a plant 2 feet high, very similar to those which received phosphate of iron ; 

 ^ oz. phosphate of magnesia produced a plant 8 inches high, with leaves 

 yellow all the season; the flowers were small, and dropped off as soon as they 

 expanded. James Donald. 



New Peas. 

 Adamson's New Matchless Pea, — Obtained from Mr. Glendinning, Chis- 

 wick Nursery, Turnham-green. A sort of white Marrow, an abundant 

 bearer, growing about 6 feet high. Pods large, flat, approaching the shape 

 of the scimitar pea, generally a little rough outside. Seeds 6 or 7. Requires 

 a distance of 4 feet between the rows. A variety of excellent quality. 



Sew Indented Marrow Pea. — Also obtained from Mr. Glendinning. A 

 sort of green Marrow, rather tall, but not so strong-growing as Knight's. 

 Pods flattish, with about large green seeds of sugary quality. Should be 

 sown 3 or 4 feet between the rows. Unquestionably a good variety ; but 

 further trial is necessary for comparison of its merits with those possessed 

 by Knight's Marrow. 



Pois a Cosse Jaune. — Obtained from M. Vilmorin, of Paris. A sort of 

 sugar pea, the pods of which are used in the way of French beans. About 

 5 feet high. Calyx and pods yellow ; the latter rather large, flat, somewhat 

 pointed but not hooked, generally much curved, one side being convex and 

 the other concave, tender, without a tough lining. Seeds 5 to 7, and may be 

 counted without opening the pod, in consequence of the latter; collapsing 

 closely round them, so that in swelling corresponding projections are formed 

 outside. The same mode of cultivation is required as is proper for other 

 peas of a similar height. Curious, on account of the yellow colour of the 

 pods ; but, like other sugar peas, not likely to be thought very useful in this 

 country. 



Dancer's Monastery Pea. — This was presented to the Society by Mr. 

 Dancer, nurseryman, Fulham, who states that he obtained it from a gentle- 

 man who procured it in Italy where it was cultivated at a monastery, and 

 hence its name. It is a fine strong-growing variety, G or 7 feet high, bear- 

 ing a succession of very large pods, rather flattened, somewhat resembling 

 those of the white Marrow, containing 7 or 6 large seeds. It is later than 

 the Auvergne ; becomes fit for use about the sime time as the Scimitar, sown 

 the same day. As it grows strong and tall, it should not be sown at less 

 than 4 feet between the rows ; nor should the peas be too thickly sown in 

 the rows. It is an excellent variety as regards productiveness, size, and 

 quality. Robert Thompson.
