SCIENTIFIC NOTES. 
ODONTOGLOSSUM MARIETTA 
(Rolfeae X Lambeauianum). 
The first plant to bloom of this very interest- 
ing somewhat reversionary cross has proved 
an extremely pretty thing. The plant was 
raised in the Chillingham collection, purchased 
and blo'Omed by J. S. Moss, Esq., of Wmters- 
hill Hall, Bishop's Waltham, Hants. 
The sepals and petals are rose colour, the 
inner two-thirds lighter, the outer third darker. 
They are copiously spotted on the lighter area 
with small light brown spots, a little inclined 
to become barred in the sepals. The lip is 
of Rolfeae form, the lower half heavily marked 
by small spots, the reniform white anterior 
half being unspotted. The crest is deep 
brown underlaid by an orange-yellow ground. 
The column small, as in Rolfeae, having deep 
brown sides and a white back. 
In form it could hardly be better or more 
symmetrical, and, considering it is but a small 
plant blooming for the first time carrying 
twelve flowers, it will make a very fine thing 
when a large plant.

From the diagram it is seen that this plant 
has three powerful species in its ancestry ; 
and it is very interesting to find that it is a 
result analogous to Ossulstonii, which contains 
the same three species. The mixing has been 
done in different ways, but the mixture in 
this case has produced a flower almost exactly 
like some Ossulstonii that I have previously 
seen. The accompanying reproduction is 
from a photograph by its owne^.

ODONTOGLOSSUM NEMO. 
We have received flowers of this Odon- 
toglossum hybrid, raised by de Barri Craw- 
shay, Esq., between O. Andersonianum var. 
Bogaerdeanum and O. Wilckeanum var. Argus. 
Both parents are, of their kinds, particularly 
well-formed good varieties, but the resulting 
hybrid shows remarkable signs of reversion 
or throwing back to the yellow grand-parental 
species. The general shape and colour of the 
flowers reminds one of a large gloriosum, but 
on examination the influence of luteo-pur- 
pureum can be clearly seen in the crest and 
formation of the lip, while the basal median 
streak of colour on the petals and the side 
wings of the column are typical of O. glorio- 
sum. Although O. crispum takes a large share 
of the parentage, very little sign of it is 
exhibited in this secondary hybrid,
