In 1895 Harms described the genus Pseudocedrela, which he 
distinguished from Swietenia and Entandrophragma by the seed 
being provided with a wing pointing to the base of the capsule, as 
against the apex (Engl. Jahrb. vol. xxii. p. 153); and in 1896 he 
used this character together with the nature of the insertion of the 
anthers in his key to the genera of Swietenioideae (Engl, & Prantl, 
Nat. Pflanz. vol. iti. 4. p. 270). 
Two additional species of Zntandrophragma were described within 
the next three years: FE. Candollei, Harms in Notizbl. Bot. Gart. 
Berlin, vol. i. 1896, p. 181, from the Cameroons ; and £. Candolleana, 
De Wild. & Th. Dur., Contrib. Fl. Congo, vol. i. fase. 1, p. 14, from 
the Congo State. The capsule and seeds were unknown in both 
cases. 
In 1905, in the course of an expedition through Buddu and 
the Western and Nile Provinces of the Uganda Protectorate, 
. T. Dawe collected material of several important timber 
trees belonging to the Meliaceae, including two species which, in 
the absence of flowers, were referred to the genus Pseudocedrela 
on account of the nature of their fruit and seeds: the wing of the 
seed pointing to the base of the capsule. As both species were 
large forest trees yielding valuable timber, it was thought desirable 
to describe them, although flowers were not known, and they were, 
accordingly, published as Pseudocedrela excelsa, Dawe & Sprague, 
an tilis, Dawe & Sprague, respectively (Journ. Linn. Soc. 
Bot. vol. xxxvii. 1906, p. 511). 
Two additional species, obviously congeneric with P. excelsa and 
P. utilis, were received subsequently from the Transvaal and the 
Gold Coast respectively, and were described as P. caudata, Sprague, 
and P. cylindrica, Sprague (Kew Bull. 1908, pp. 163, 257). 
During a visit to the Budongo Forest early in 1910, Mr. Dawe 
obtained flowers of Pseudocedrela utilis and P. cylindrica, which he 
has forwarded to Kew. These showed the structure characteristic 
of Entandrophragma, namely, a stipitiform disk and « partitioned 
staminal tube. A capsule of Entandrophragma angolense preserve 
in the Kew Museum was accordingly examined and it was found 
that the wing of the seed pointed to the base of the capsule just as 
in Pseudocedrela. It thus became evident that the seed of Entan- 
drophragma had been incorrectly described, and that several of the 
species published under Pseudocedrela would have to be transferred 
to Entandrophragma. 
The mistake in the description of the seeds appears to have arisen 
as follows : Casimir De Candolle described the seeds as “superne 
alata,” apparently meaning thereby that the seeds were winged at 
the end opposite to their place of attachment. Unfortunately, 
however, the phrase “semina superne alata” had been used in 
quite a different sense by Bentham & Hooker (Gen. Pl. vol. i. 
p- 338) and by C, De Candolle himself (Monogr. Phan, vol. 1. 
p. 723), as meaning that the seeds were provided with a wing 
pointing to the apex of the capsule ; and in this more usual sense 
it was naturally interpreted by Harms, 
Although flowers are not known of Pseudocedrela excelsa and 
P, caudata, it may safely be assumed that these two species belong to
