Nymphaea kewensis (N. Lotus var. alba x N. Devoniensis). 
Raised in 1885; flowers large, 6 inches in diameter, with rosy- 
red petals and golden-yellow stamens. Habit as in N. Lotus. 
IN. Devoniensis itself is, by some botanists, referred to N. Lotus ; 
others consider it to be a hybrid between N. rubra and N. Lotus. 
N. kewensis is figured in the Botanical Magazine, t. 6988. 
Primula kewensis (P. floribunda x P. verticillata). 
This hybrid appeared as a chance seedling among a batch of 
P. floribunda in 1899. It was exhibited at the meeting of the Royal 
Horticultural Society, February 27th, 1900, and was awarded a First 
Class Certificate. See the Gardeners’ Chronicle, 1900, xvii., pp. 130, 
195, fig. 63 ; Gardeners’ Magazine, 1900, 232, with figs. oe 
During the summer of 1900 the supposed parents were artificially 
crossed, and good seed was obtained from P. floribunda ; a proportion 
of the resulting plants proved to be true P. hewensis 
D 
uring the summer of 1910 the following crosses were again 
ade :— 
No.1. P. verticillata* x P. floribunda. 
» 2. PP. floribunda x P. verticillata. 
» 3. LP, verticillata x P. floribunda var. isabellina. 
» 4. WP. floribunda var. isabellina x P. hewensis (type). 
» 5. PB. floribunda var. isabellina x P, hewensis (seedling 
form), 
6. P. kewensis x P. floribunda var, isabellina. 
bby 
All the above crosses produced good seed with the exception of 
No. 6. No. 1 produced a quantity of what appeared to be good 
seed, but only a few plants have been raised ; so far they are all 
unflowered. 
Rehmannia Briscoei (R. Henryi x R. angulata). ie 
This cross was made in 1908, the plants flowering in 1910. 
R. Briscoei—raised by Messrs. J. Veitch & Sons, and figured in 
the Gardeners’ Chronicle, 1910, xlvii., 188—is the result of the 
reverse cross. The colour of the flowers is the same in the two 
Rehmannia (R. Henryii x R. glutinosa). 
A few =e have Ee raised this year but as yet have not 
flowered. 
Rhododendron kewense (R. Griffithianum x R. Hookeri). _ 
Crossed in 1874; flowered in the Temperate House in May, 
1888, It has proved to be hardier than either parent, eee 
having withstood several winters in the Rhododendron aap : 
ew. It forms a sturdy, much branched plant, with agi : 
10 inches long by 2 inches broad ; the flowers, which are dispose 
: ted without being 
* P. verticillata Iso emasculated and carefully protected 
fertilized. ied no pts aie formed ; the experiment was made in order to see 
whether ovules might not be produced by vegetative means,
