Cypripedium Sallieri maculatum or C, nitens 



Cypripediiim Sallieri maculatuiu 

 or C. nitens maculatum as it should 

 be called is a beautiful hybrid be- 

 tween some good variety of C. in- 

 signe and C. villosum. • The center 

 of the large dorsal sepal is a fine 

 shade of green, spotted with almost 

 black and surrounded by a broad 

 band of pure white. The color of 

 the petals and pouch are about the 

 same as in ordinary forms of C. in- 

 signe. As to size and shape of the 

 flowers the photograph speaks for it- 

 self, being a life-size reproduction of 

 the flower. It is a very free grower 

 and bloomer. 



Our stock was obtained from 

 Siebrecht & Sons of New Rochelle, 

 N. Y., who claimed to be the raisers 

 of the hybrid, but recently Lager & 

 Hun-ell of Summit, N. J. carry the 

 same thing in stock.

THE LARCH APHIS IN SCOTLAND, ETC. 



The members of the northern branch of the Eoyal 

 Scottish Arboricultural Society of Scotland on their 

 excursion to the estate of Fasque in Kincardineshire 

 were conducted by Mr. A. Dewer, the factor on the estate 

 for Sir J. Gladstone, Bt., to inspect the great damage 

 done by Aphis to young larch trees — many of the latter 

 being dead or nearly so. The Japanese larches were on 

 the contrary quite free from the pest. Sir John Glad- 

 stone who accompanied the visitors drew attention to 

 two magnificent larches, one on either side of a drive. 

 These trees are about 80 feet in height, and perfectly 

 straight in the bole. A fine specimen of the common 

 beech, standing on th^ lawn in the front of the castle 

 measures 15 feet, 6 inches in girth, at breast height. 

 This tree was planted with others in 1707 to commem- 

 orate the union of England and Scotland. 



ROYAL HORTICULTURAL SOCIETY'S SCIENTIFIC COMMIT- 

 TEE 



At a recent meeting of this body Mr. W. Cuthbertson 

 made some observations on the Spencer type of sweet 

 peas having been found a poor seed producer, showing 

 flowers and photograph of flowers. The causes he con- 

 sidered to be the following. First — The keel is not 

 constricted and consequently the stigma and anthers are 

 not pressed together as in the older type of flower. 

 Second — The keel being open, contributes to the drop- 

 ping of the pollen to the bottom of the keel without 



coming in contact with the stigmatic point. In the 

 old type of flower this could scarcely happen. Third — 

 In many of the waved forms the style grows beyond the 

 antlers before these separate (dehisce), and the point 

 is thus not brought into contact with the pollen. Fourth 

 — In some, more especially salmon and orange colored 

 varieties, the anthers are nearly sterile. Fifth — The 

 waved standard does not, although large, act as an um- 

 brella in bad weather. The Unwin, a moderately waved 

 type of sweet peas is an abundant seed producer; the 

 keel resembling in form that of the old form of keel. 



ACTINIDIA CHINENSIS, ETC. 



It is a woody climber belonging to the natural order 

 Ternstroemiaceae , and a native of China, as A. arguta 

 is of Japan, and also a climber possessed of much vigor 

 and retaining its leaves till late in the autumn. A. chi- 

 nensis has sub-orbicular leaves, and yellow flowers about 

 1 1-2 inches in diameter, borne freely on the mature 

 growths in its native country. In order to obtain fruits 

 it is advisable to plant male and female plants in near 

 proximity to each other. The fruits are of a russety 

 green color, ripening in October and are excellent for 

 dessert and preseiTing. When planted out of doors a 

 warm position for the plants should be chosen, such as 

 suits the peach in Great Britain. The plant was fig- 

 ured in Gardeners' Chronicle, July 31, of the present 



vear.
