584 JOUKNAL OF THE ROYAL HORTICULTURAL SOCIETY. 



Stokesia cyanea. By Ad. Van den Heede (Bev. Hort. Beige, t. xxvii. 

 p. 220, Oct. 1901). — Nat. ord. Compositce ; native of Carolina. It bears 

 large blue flowers 4 inches in diameter. It grows to about 7 or 9 inches 

 high, useful therefore as a window flower. It cannot stand prolonged or 

 severe winters. — G. H. 



Strawberries, Prolong-ing- the Season of. By G. Wythes 

 {Gard. Chron. No. 759, p. 24; 13/7/1901).— An interesting note in 

 which it is pointed out how " the Strawberry season may be extended by 

 growing certain varieties, and in diverse positions." — G. S. S. 



Streptocarpus Vandeleuri and S. Armitagei. By E. G. Baker and 

 Spencer LeM. Moore {Journ. Bot. 464, p. 262; 8 1901).— Descriptions 

 (A i^\o new species, near ,S'. Dminii, from the Transvaal. — G. S. B. 



Strobilanthes gOSSypinus, T. Anders. By Sir J. D. Hooker (Bot. 

 Mag. i'dh. 11^0). — Nat. ord. Acanthacece; tribe Bitelliece. Native of the 

 Nilghiri Hills. An erect shrub, covered with a fulvous tomentum, flower- 

 ing once only, when from six to seven years old, and then dying. Flowered 

 at Kew, 1900, from seed sown in 1887. Flowers, with corolla, | inch 

 long ; tube, ventricose ; lobes, pale blue. — G. II. 



Sug-ar-cane. By W. C. Stubbs {U.S.A. St. Bd. Louis. Ball. 59).— 

 In this bulletin are given the results of ten years' experiments in held 

 and laboratory, undertaken with a view to improving the cultivation of 

 the Sugar-cane in Louisiana. 



The bulletin treats of : — 



(1) The preparation of the soil, strongly emphasising the necessity of 

 proper and sufficient drainage, as well as requisite ploughing. 



(2) The kind and quantity of cane to plant. Experiments have shown 

 that the tops of the cane may be used for seed (instead of reserving the 

 whole cane for this purpose), to the great saving of money and labour. 



It has also been proved that the best results are obtained by planting 

 the largest canes, rather than medium and small. 



(3) The proper fertilisation. It was found that, in applying ammonia 

 and potash as manure, sulphates were the best form. Phosphates were 

 found to increase the tonnage. 



Experience and experiments tended to prove that there are no known 

 fertilisers which will increase the sugar content. 



(4) The rational modes of cultivation, showing that " cultivators " are 

 to be preferred to " ploughs." — C. H. C. 



Sug'ar-cane, Cross-fertilisation of. By Prof. d'Albuquerque {Jour. 



Imp. Dep. Agr. W.I. vol. i. No. 2, p. 182). — It will interest hybridists to 

 know that in Sugar-canes " the average size of the mother closely governs 

 (with exceptions) the size of the offspring," and the same with regard to 

 colour ; but in respect of an increase of sugar no rule can be established, 

 and only repeated trial and selection of the best seedlings can at present 

 be relied on. — W. W.
