morphology of tho various members of the order ; and some 

 interesting photographs of the Jnliania trees, taken by Dr. Rose 

 in Mexico, are reproduced in the text. All the representatives of 

 this order are dioecious shrubs or small trees with pinnately- 

 compound leaves, which are deciduous. The flowers are small and 

 inconspicuous, the female particularly so, but the male are in 

 catkins, not unlike those of an oak. 



The curious samaroid or winged composite fruit is, however, the

most characteristic features of the Jul ianiaceae 



They are pendulous, frequently hanging in dense clusters, and 

 tne seed-vessel proper is borne at the upper end of the flattened 

 wing-iike stalk. The peculiar ovule is described in detail with 

 numerous figures, and a note on the microscopic structure by 

 Mr. .Boodle is included. It is characterized by a remarkably large 



runicular appendage.

a so certain points of resemblance to the Juglandaceae, but the 

 absolute separation of the sexes, and the very great diversity of 

 noral structure of the sexes— associated with pinnate leaves- 

 otter a combination of characters probably without a parallel.

The genus Sageretia in Africa. — In an interesting collection of 

 feornaliland plants, received recently from Dr. R. E. Drake- 

 Brockman through the Colonial Office, was a specimen of a 



grockman through the Colonial Office, was a speci 

 Khamnaceous plant which proved to belong to Sageretia— a 

 so far as we are aware, not recorded hitherto from Africa, 

 distribution of Sageretia as previously known was as folio 



a genus,

southern United States, Mexico, Central America, South America. 

 China, India, Malaya, Afghanistan, Baluchistan, Persia, and 

 •Ir/pical Arabia. 



/ Br. Drake-Brockman's specimen (No. 389) belongs to the relatively 

 'glabrous form of Sageretia Brandrethiana described by Boissier, 

 FL Orient., vol. ii., p. 22, and mentioned by Brandis, Indian Trees, 

 P- 174, who suggests that S. Brandrethiana should possibly be 

 united with S. theezans, a point which must be left to a mono- 



—- >in g from its supposed congeners 

 stipules and flattened, orbicular seeds. 

 . The same form of S. Brandrethiana has been collected in the 

 Italian cotony of Eritrea, by Schweinfurth and Riva, .No. U4Ui f 

 and was distributed as Bercliemia y emends. 



The most important distinction between Berchemia and Sageretia 

 seems to be that the former has a 2-celled .endocarp, fatter 

 2 or 3 pyrenes. The pyrenes of Sageretia are toWtt 

 mdehiscent in Bentham and Hooker f., ^nem Banta^

 and elsewhere ; but the writer has found that they dehisce by
