Q. arachnites, and rare examples of O. lutea and O. arachnitiformis. We 
indentify it with a plant described in 1887 as O. Aschersonii, Nant. (Bull.. 
Soc. Bot. France, xxxiv, p. 423), as a hybrid between the species named, that 
had been found in the villages of Vaux and Champagne, near Isle-Adam 
(north of Paris), by P. Bergon, It had previously been found in Germany, 
and had been referred:to O. arachnitiformis, but M. de Nanteuil considered 
it different; and doubted whether the latter was of hybrid origin. This is 
the plant figured as O. arachnitiformis by Ascherson (Berl. Monatschr., 1878,’ 
PP: 457-459, t. 6), flowers of the two supposed parents, O. aranifera and O. 
arachnites, being also included. It was found near Jena, Germany, in May 
of the previous year, and this plant may be regarded as the original of O. 
Aschersonii, Nant. The sepals and petals are pale green, the latter narrow - 
and elongated, and the lip combines well the characters of the two parents: 
Lastly, there is a plant of O. Bertolonii with three bulbs, which was 
Collected at Port de Bouc, Bouches du Rhone, and M. Denis remarks that 
it is the first time he has seen this anomaly, which must be rare. He adds 
that O. Bertolonii is abundant in this locality, mixed with O. lutea, O. 
aranifera, and a very few O. arachnitiformis. 
We note with pleasure that M. Denis is continuing his very instructive 
experiments, and he hopes to be able to send us further examples. R.A.R. 
ONCIDIUM LURIDUM FROM PaNAMA.—We have received for determin- 
ation from Mr. C. W. Powell, Balboa, Canal Zone, Panama,a sketch ofan 
Oncidium, which we think belongs to O. luridum, Lindl. Part of the 
inflorescence was sent separately, but the packet, unfortunately, arrived 
broken and without contents, so that we cannot be certain of the determin 
ation. The sketch with the flowers would have been ample, but without 
them the necessary details are missing. Mr. Powell compares the plant 
with O. Lanceanum, but the inflorescence is much-branched, arching, four 
feet long, and bore 93 flowers. The flowers differ from O. Lanceanum in 
Shape, and the sepals and petals are described as barred and dotted with 
tosy-brown, the lip still more dotted, and the crest of the lip deep rose- 
purple with yellow teeth. The column is yellow, and the anther cap pale 
rose, yellow at the base, and with violet awns. So far as the sketch goes, 
in the absence of flowers, it might be O. carthaginense, Jacq., but we have 
as yet no evidence that that species occurs in Panama, and we chiefly 
favour O. luridum because some years ago Messrs Sander sent to Kew a 
specimen which was said to have been received from Panama with O, 
ampliatum, and this proved to be O. luridum, which extended the area of 
the species. Perhaps Mr. Powell will be able to complete the specimen 
later. It would be interesting to, know . more of the Orchids af 
Panama.—R.A.R, = :
