what the plant specially requires to be supplied to it in the soil, If 
the Yeheb plant grows well in the soils indicated by the foregoing 
analyses, it is not because of the richness of the soil; it may 
possibly be because of its poverty.” 
At Kew, Yeheb seedlings have been raised in ordinary soil under 
moist tropical conditions. The plants have been found to be very 
slow in growth; a few have flowered but no seeds have been 
ripened.

Mr. Max Leichtlin, of Baden-Baden. This B. Martiana gracilis 
was crossed with B. racemiflora rosea grandiflora by Messrs. 
Lemoine, producing a plant which was distributed in 1885 under 
the name of B. Martiana grandiflora, the plant figured in the 
Botanical Magazine. None of these facts are mentioned by 
the author of the note and figure in the Illustration Horticole 
(ser. Vi., ii. p. 98, fig. 14), and possibly they were unknown to him. 
Two other hybrids are mentioned, which are not concerned in the 
ancestry of the present plant. It now remains to trace the histories 
of the plants mentioned. 
Begonia racemijlora does not appear to have ever been described 
and there is no reference to it in the Index Kewensis. It is, 
however, mentioned by Fournier (Journ. Soc. d’Hort. de France, 
1879, p. 202) as “ B. racemijlora, Ortgies, in Lem. Cat. Janv. 1877, 
no. 7 5, p.7 "a an imperfectly known Mexican species which will not 
hybridise : with the tuberous Begonias. Messrs. Lemoine now 
speak of it as having flowers of moderate size, white or with rose 
tint, developed in axillary bunches that show themselves all on the 
same side of the inflorescence. ‘They also add that the species is 
lost to cultivation, as well as the first hybrids raised by them from 
it. The characters mentioned suggest that it may be the plant 
known in gardens as B. Martiana var. racemiflora. 
The B. diversifolia mentioned is probably B. diversifolia, Grah. 
in Edinb. New Phil. Journ. vol. viii. (1829), p- 183; Bot. Mag. t. 
2966 ; which is the B. gracilis var. diversifolia, A. DC. 
B. Martiana gracilis is figured in colour (Rev. Hort. 1883, p. 372, 
with plate), and is much like a stout form of B. Martiana, Link 
and Otto, or possibly the nearly allied B. bulbifera, Link and Otto, 
which De Candolle retains as distinct.
