Iris Kaempferi, Special Culture of. By Jules Rudolph (Rev. 

 Hort. No. 20, Oct. 16, 1902, pp. 478-9). — One woodcut of varieties. 

 Description of cultivation for cut flowers in wooden trenches, irrigated at 

 first, about the middle of Apiil or a month after planting, once a day, 

 and subsequently twice a day, until flowering ceases. Directions are also 

 given for raising from seed, sowing in warmth in March ; some flowers 

 showing the second year, when the plants are transferred to a site on a 

 stream-side or other humid place, and utilised as outdoor decorative 

 groups. Well-manured soil is an essential to success. In a subsequent 

 number (No. 21, Nov., 1902, pp. 505-7), S. Mottet states that this Iris is 

 far more accommodating as regards water supply than the above implies, 

 water being only given in the dry season, and yet they flower as freely as 

 when inundated, though perhaps not so large. — C. T. D. 



Jack Fruit, Artocarpus integrifolia. By the Manager, State 

 Nursery, Kamerunga (Qu. Agr. Joiim. xi. pt. 3, Sept. 1902, with plate). — 

 This paper gives a detailed account of the Jack fruit tree, its botanical 

 history, varieties, use of the fruit, timber, &<$., and methods of cultivation. 

 It is found mostly in old gardens in North Queensland, but is not much 

 recommended. In fact it is remarked that " the principal use of the Jack 

 tree in the northern portions of Queensland would be as a fodder, 

 and in this way it would probably prove as valuable as the Algaroba, or 

 Mesquit Bean tree." The leaves are readily eaten by stock, and it is 

 a tree that will grow in a dry as well as in a hot climate. — M. C. C. 



Jacobinia chrysostephana. Ed. (Jo urn. Hort. Dec. 11, 1902, 

 p. 543). — An engraving of this neglected stove plant, of which a group 

 was exhibited on Nov. 18 at the Drill Hall by Messrs. Yeitch. It is 

 figured in Bot. Mag. tab. 5887, under the generic name of Cyrtanthera.

Japan, Horticulture in. Ed. (Le J«,d. March 20, 1902, p. 84).— 

 The gayest month for flowers near Tokio is April. In that month a 

 grand " Garden Party " [sic] is given in the Imperial Gardens to privileged 

 guests. — C. W. D. 



Justicia Kaessneri. By Spencer Moore (Jou rn. Bot. 478, p. 345; 

 10/1902). — Description of a new species, collected by Mr. Kassner at 

 Gadu, British East Africa, from specimens in the Natural History 

 Museum. — G. S. B. 



Kalanchoe Kirkii. By Sir J. D. Hooker (Bot. Mag. tab. 7871).— 

 Nat. ord. Crassulacece. Native of Nyassaland. The whole plant is 

 glandular-pubescent. Leaves ovate-lanceolate, crenate. Cymes terminal, 

 with crowded flowers, with 4-petailed orange-red corollas. — G. II. 



Ker, John Bellenden. By James Britten (Joum. Bot. 480, pp. 

 119-422; 12/1902). — A chronological enumeration, with annotations, of 

 Ker's botanical papers. A reclamation of priority for some of Rox- 

 burgh's descriptions of species of Criniun and Pancratium is the chief 

 feature in these notes. — G. S. B.
