Cycadeae, Reproductive Organs of. Part I. By Marie C. Stopes 

 (Flora, xciii. 1904, pp. 435-482; 37 cuts).— This paper deals only with 

 the carpel and ovule in the genera Bowenia, Cycas, Dioon, Zamia, 

 Ceratozamia, Macrozamia, and Encephalartos. The integument of the 

 ovule is known to be drupe-like, with an outer fleshy and an inner bard 

 layer, which are merely due to differentiations in liquefication, and have 

 a common vascular system. An inner fleshy layer is now demonstrated, 

 with its proper vascular system, and is homologised with the (distinct) 

 internal coat of the fossil Lagenostoma. Details are given of the forma- 

 tion of the pollen-chamber at the apex of the nucellus.— M. H. 



Cyclamen hiemale, nov. spec. By Herr Friedrich Hildebrand 

 (Gartenflora, Feb. 1, 1904, p. 70). — This hardy Cyclamen was sent from 

 Mersina in Asia Minor. In appearance it is something between G. coum 

 and C. ibericum ; in fact, some of our English authorities give this 

 Cyclamen under C. coum. Herr Hildebrand, however, claims that this 

 is a new species. He gives its time of flowering as from November to 

 January. — B. C. B. N. 



Cyclamen, New. By F. Hildebrand (Gartenflora, Feb. 1, 1904, 

 p. 70). — In the spring of 1898 a carefully prepared monograph of the 

 genus Cyclamen was published by this botanist, in which thirteen species 

 are described, mostly from living specimens, being all that were then 

 known to him. Of these thirteen species eight or nine have been known 

 in British gardens for many years, but none of them more generally and 

 successfully grown than C. versicum (C. latifoliwn, as we are now told to 

 call it), which, under long and skilful cultivation, has become the facile 

 princepsoi the genus. Since the publication of Hildebrand's monograph, 

 no fewer than five more species or sub-species have come to light previously 

 unknown to science : — (1) Cyclamen libanoticum, from the historic Mount 

 Lebanon in North-West Syria, is described in Engler's " Jahrbuch " for 

 1898, p. 477, as a suitable plant for cultivation, the seedlings of each 

 generation improving, as regards their flowers, in size, colour, and varia- 

 tion. (2) C. Pseud-ibericum, which appears to be a sub-species of 

 C. ibericum, but differing chiefly in its tubers and larger flowers. 

 (3) G. Mindlerii, of Greek origin, found by Herr Mindler on the island of 

 iEgina, but not yet in cultivation. (4) C. Meliarakisii, also of Greek 

 origin, and named after a former director of the Botanic Garden at 

 Athens, and recently introduced to European gardens through Max 

 Leichtlin, of Baden-Baden ; it may, however, prove to be C. grcecum or a 

 variety of it. And (5) G. hiemale, a discovery of Herr Siehe, who sends 

 it from Mersina in Asia Minor. This may prove of some value as a 

 winter-flowering plant, being quite distinct from G. persicum (C. longi- 

 folium), with handsome foliage and carmine-red flowers with a dark red 

 spot.— A. H. K. 



Cyclanthaceae, Anatomy Of. By Ernst von Oven (Rogasen) 

 (Beih. Bot. Cent. xvi. pp. 147-198 ; with one plate). — Gives a description 

 of the anatomy of the leaves, petioles, peduncle, and roots in ten to twelve 

 species of Cyclanthus, Carludovica, and Ludovia. The author selects as
