the umbel) being the largest, all obtuse, spreading, waved, 
of a beautiful blue color. Stamens at first erect. Fila- 
ments and Anthers whitish. Germen flat, nearly orbicular, 
reddish, dotted, and very glandular: disk flattish, white : 
Styles linear. Fruit between orbicular and reniform, or, 
rather, composed of two almost exactly orbicular hemi- 
carps *, quite flat, rough or granulated on the surface, 
having two semicircular, elevated lines or vitte in the disk, 
and athickened margin. Styles persistent. Seed pendent, 
obovate. 
With the exception of the flowers of some species of 
Erynerum, I am not acquainted with any Umbelliferous 
plant whose blossoms are blue. It was, then, with no small 
degree of surprise and pleasure that I received from my 
friends, the Messrs. Sepuerps, in the month of July of this 
ear, 1828, specimens of this most singular plant, which they 
ad raised, at the Liverpool Garden, from seeds sent by Mr. 
Fraser from New Holland. It has since flowered at Edin- 
burgh and Glasgow, and, I believe, too, at the Horticultural 
Society’s garden, as well as at the Geneva garden, under the 
care of Professor De Canpo.ze, the seeds having been de- 
rived from the same source as those at Liverpool. Again, 
Mr. R. Cunnineuam, of Kew, has been so good as to 
convey to me the information, that it has been cultivated at 
the Royal Gardens there from seeds sent by his brother, Mr. 
Atian Cunnineuam, under the name of TracHyMENE cyanea 
of his MSS. ; a name I should gladly have adopted, as given 
by, probably, its first discoverer, but that it has already 
been published by Dr. Granam, under that of cerulea. 
Professor De Canpouue intends separating this as a Genus, or 
Subgenus, from Tracuymene of Runce (Azorella, LABiLLAR- 
DIERE) on account of its different habit, bright blue flowers, and 
the peculiar structure of the fruit, very much resembling that of 
a Biscutetua. In my specimens of true TRACHYMENE, of which 
I have several species, the Umbels are compound. I may observe, 
that the TracuymeEne incisa of RupGe and Siezer will belong 
to the same groupe as the present plant, but in a dried state it 
does not appear that the flowers are blue. 
Dipiscus cyaneus is one amongst a few of the Umbelliferous 
plants which eminently deserves a place in every collection, and in — 
all probability it will be found to succeed well in the open air.
