476 REMARKS ON VIBURNUM AND CORNUS. 
flower and fruit as above indicated, and also by its white glistening stems and branches, the epidermis of which is apt 
to peel off in the manner of many Loasacex. The white flowers, 14-1} inches in diameter, at last turn pale-red ; the 
very slender capsule, connected by a very thick base with the stem, is usually 1}-1? inches long, and spreads at right 
angles, or is curved or twisted in various directions. Seeds smooth, dark-brown, lance-linear and usually very acute 
at one end, and 0.8 line long; var. 8. has smaller (0.6 line) and obtuse seeds. According to foliage and pubescence 
I arrange the specimens before me under the following varieties : —- 
; a. Foliis basi in petiolum brevem attenuatis. 
Var. a. NuTTALLII: erecta glabriuscula seu puberula, simplex seu ramosa; foliis linearibus seu lanceolatis seu 
oblongis integris vel plus minus dentatis. Here belongs (4. pallida, Dougl., with its variety leptophylla, Torr. & Gr., 
as already indicated by Prof. Gray. Nuttall describes this form as sometimes 3 feet high, and Geyer notes that in the 
sandy plains of Devil’s Lake and at the sources of St. Peter’s River it forms shrubby bushes of the size of Spartium 
scoparium, growing even 4 feet high ; but it seems more usually between one and two feet high. Leaves 1-24 inches 
long re 1-6 lines wide. One of the broadest leaved forms is Fendler’s N. Mex. No. 224. 
yr & av NCINATA : branchiato-ramosa, patula, glabra, puberula seu canescens; foliis lanceolatis grosse seu 
sinua’ Sie ntatis. This is (2. pinnatifida, Gray, Pl. Fendl. p. 43 insieal dope and most of the specimens No. 223, all 
those with the private number 243), Fendler gathered it near Santa Fé; Fremont in his 3d Expedition collected a 
glabrous (No. 222) and a very canescent (No. 178) form, the latter with singularly short but apparently fertile 
capsules, scarcely 3 lines long. 
b. Foliis basi lata truncata sessilibus, [335] 
Var. y. BREVIFOLIA : tota glaberrima, erecta, ramosissima ; foliis late ovatis abbreviatis grosse dentatis. 
Sandhills south of El Paso, Dr. Wislizenus, No. 99. Leaves dark green, while all the other forms are pale or grayish, 
4-6 lines long, bia or often rounded at the end. 
OCALYX : erecta, parce ramosa, a foliis lanceolatis a lanceolato-oblongis sinuato- 
dentatis. Las im New Mexico, Dr. Wislizenus, No. satin t is no doubt Nuttall’s @. trichocalyx, Torr. & Gr. 
Fl. |. ¢., the specific identity of which with @. a Prof. Gray has already indicated. The long hair on the 
stem, ovary, and especially the calyx, consists of a single cell, remarkably broad at base, tapering to an acute point ; — 
it is however the form of hair I find in all long-haired Wnothere. 
V. REMARKS ON VIBURNUM AND CORNUS. 
FroM THE TRANSACTIONS OF THE ACADEMY OF ScIENCE oF Sr. Louis, Vou. II. 1866. 
_ Dr. ENGELMANN made some remarks about the fruit and seed of different species of Vibur- [269] 
num. Unfortunately botanists too frequently neglect to gather the ripe fruit, and the herbaria 
that he consulted furnished but scanty material for the interesting investigations he had instituted, 
and which he intended to prosecute. The fruit, he stated, was described as an oval drupe or berry, 
red, dark blue, or black, with a juicy and edible pulp, and a crustaceous stone containing the minute 
embryo in a fleshy albumen. He found the berries of different sizes, and generally more or less com- 
pressed, but, on the whole, offering no useful diagnostic characters, as might be expected of such a pulpy 
fruit. The pulp contains, as is well known, saccharine matter (capecially in our common “ black 
haw,” Viburnum prunifolium), or it is more or less acidulous (e. g. in the “tree-cranberry, V. Opu- 
lus); but he had found as a remarkable exception one species, ‘tie 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 rather 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) ruminated, 
especially in the thick-seeded species. 
In the following table are enumerated all the species the fruits of which he could examine : —
