Dendrobium moschatum. By James Britten (Journ. Bot. 476, 

 p. 281 ; 8/1902). — An explanation that Swartz's name takes precedence 

 of D. Calceolaria of Hooker, formerly figured and described by Buchanan

Dendromecon rigidum. Anon. (Journ. Hort. p. 102; July 31, 

 1902). — An engraving is given of this rare Californian shrubby perennial, 

 which has somewhat of the habit of the better known Bomneya 

 Coulteri. Though quite hardy, and introduced into cultivation in 

 England by David Douglas many years ago, it is very difficult to satisfy, 

 and very few specimens are known. It is growing well at Kew on the 

 west wall of the Cattleya house. — C. W. D. 



Dianthus plumarius hybrid * Sophia Ragionieri.' By Angiolo 

 Pucci {Bull. B. Soc. Tosc. Ort. vi. p. 166 ; June 1902).— Exhibited by 

 Dr. Attilio Ragionieri. It was raised from seed of Dianthus plumarius 

 fertilised by pollen from D. Caryophyllus. It resembles the former in 

 its very glaucous narrow leaves and its compact habit, and the latter in 

 its dimensions. It is about 40 cm. high ; the flowers are borne on rigid 

 stalks about 30-35 cm. long, and consist of a great number of fringed 

 petals of a dull sulphury-pink colour and pistils of a much brighter colour, 

 projecting from the centre ; they are about 8 cm. in breadth, and possess 

 a delicious odour, which is that of D. plumarius, but slightly recalls the 

 scent of the other parent. The plant grows freely and produces abundant 

 flowers. It flourishes in the open, forming handsome borders, and 

 flowering about the middle of May. If grown in a pot and allowed to 

 become old it forms, if properly supported, fine metre-high pyramids. It 

 may be gently forced. — W. C. W. 



Dinacria sebaeoides. By S. Schonland and E. G. Baker (Journ. 

 Bot. 476, p. 282; 8/1902). — Description of a new Crassulad from 

 Beaconsfield, near Grahamstown, South Africa, by Dr. Schonland, the 

 collector, " a little glabrous annual." — G. S. B. 



Dischidia hirsuta. By Sir J. D. Hooker (Bot. Mag. tab. 7,853).— 

 Nat. ord. Asclepiadece, tribe Marsdeniece. Native of Malaya. It is one of 

 the smallest-leaved species, the leaves being about 1 inch long. The stem 

 clings like Ivy, and this is the only species which has flowered in Europe. 

 The flower is ^ inch long with a globose, blood-red corolla. — G. H. 



Dischidia with Double Pitchers. By H. H. W. Pearson (Journ. 

 Linn. Soc, Bot. vol. xxxv. p. 375, pi. 9 ; July 21, 1902).— The genus 

 Dischidia is notable from the fact that the growth of some of the leaves 

 is very different from that of the others. In 'these the apical growth seems
