Edwards Whitaker’’). In general characteristics the ‘‘ Henry 
Shaw’’ is a replica of N. castalitflora, in fact to such an extent 
that it is impossible to tell one from the other until the flower- 
ing period. ‘The flowers are light campanula-blue. The petals 
and stamens are the same in number, the latter being light 
campanula-blue at the apex and lemon-chrome below. The 
sepals are prominently hooded and solid green on the back, 
all dark markings being absent. The seedling leaves are 
prominently marmorate on the upper surface, while the devel- 
oped leaves, like those of the parent, are flushed with pinkish 
red on the under side, the upper surface being green sparsely 
spotted with light brown. 
x NYMPHABA “AUGUST KOCH” PRING 
(N. pennsylvanica < N. ‘‘Mrs. Woodrow Wilson’’) 
This interesting viviparous hybrid was produced through 
insect agency from seed of Nymphaea pennsylvanica collected 
at Garfield Park, Chicago. Four of the plants were sent to 
the Garden in the fall of 1921 to be grown for identification 
during the following summer. All of the plants have fully 
developed characters which suggest the hybrid N. ‘‘Mrs. 
Woodrow Wilson”’ as the staminate parent, but the purple 
markings dominant on the bud of both parents is entirely 
absent. The leaves are a replica of those of ‘‘Mrs. Woodrow 
Wilson,’’ the under side being flushed with pink, contrasting 
with the green venation, and the upper surface being green 
and bulbiferous at the summit of the petiole. Two of the 
specimens show the sinus lobes overlapping, while the remain- 
ing two are open. The flowers of the open-lobed plants are 
slightly lighter in color. The darker-flowered variety has 
been selected as the type.
