REMARKS ON VIBURNUM AND CORNUS, 
. By Dr. G. ENGELMANN. 
(From the Transactions of the Acad, of Set. of St. Xotm, vol. II., p. 260- 271.) 
He the# made some remarks abbiit thb ftm?! and seed of different species 
Oi Viburnum. Unfbrturiatery bptams'ts ; tod Frequently iiegtect to gather the 
ripe fruit, and the herbaria that he consulted furbished but scanty materia! 
for the interesting'investigations he Had instituted, and which he intend¬ 
ed to.prosecute, #as described as an oval drupe or 
berry, red, dark Hide, Or black, with a juicy and edible pulp 1 ; and a crusta- 
ceous stone containing the minute embryo in a fleshy albumen. He found 
the berries of different sizes and generally more or less compressed, but, 
on the whole, offering no useful diagnostic characters, as might be expect¬ 
ed of such a pulpy fruit. The pulp contains, as is well'known, saccharine 
matter (especially^ in our common “ black haw,” 1 Vibumum^ptunifolium), or 
it is more or less acidulous (e. g. in the “ tree-cranberry,’*■ V. Opulus) ; but 
he had found a.s a remarkable exception.One species, the rare V. scabrellum\ 
specimens of which, collected in Mississippi by Prof. E. Hilgard, were 
examined, with a pulp as oily as that of any Nyssa: or of Olea itself. 
The most important diagnostic characters are found in the stone and 
the albumen. The stone is either flattened or it is thick, even, or marked 
with longitudinal grooves and ridges; the albumen is described as fleshy,' 
but he Would father call it horny, and it contains some oil; it is even and 
uniform, principally in the flat-seeded species, or more or less folded, or 
(as it is termed) ruminate^, especially in the thick-seeded species. 
In the following table are enumerated all the species the fruits of which 
he could examine.
