passes it. In fact, I have never seen anything outside the tropics 
which, in my opinion, would compare with the large masses of deep 
scarlet berries displayed by P. arbutifolia. The species was not 
abundant, but was noticed in several places, growing usually in clefts 
of rocks, and forming a tall shrub of 5-10 feet in height. It was 
observed in cultivation at two places along the road leading to the 
Point, in one instance forming a tree some 20 feet high. Another 
peculiarity of the vegetation of the I'oint which Mr. Bruton omits to 
mention is the remarkable form assumed by the few hemlock-trees 
which grow there. One was noticed which had an elevation of not 
more than six feet, but which expanded a rod or more (I write from 
memory, no measurements having been taken), the dense flat top sup- 
ported on a comparatively massive straight trunk a foot or more in 
diameter and several feet iij height. I was told of a tree (said to be a 
pine), of similar shape, growing at the mouth of the *'ice cave'' which 
expanded more than 30 feet, although no taller than the one just 
described.

Teratological Notes. — In the Bulletin of July, last year, I re- 
corded the fruiting in my garden of di,n An'scema triphyllum with 
twin spadices. I have this last summer received from my brother, 
Professor L. W, Bailey of Fredericton, New Brunswick, Canada, 
who was ignorant of my previous observation, a specimen in the 
same condition. The flowering portion is simple, and so is the con- 
stricted neck, but above, the club-shaped appendages are distinct. 
Of these, one is taller than the other. The discoverer does not indi- 
cate any change in the surrounding spathe. 
I have an English walnut with three cotyledons. This reminds 
me to say that after sending my note on //'^^///ttv? (present volume, 
page 82), I found one in my yard Avith three perfect cotyledons.

The Flora of the Country Bordering the Rio Grande, in Chihuahua 
and lexas, — In a paper read before the New York Academy of 
of Sciences. Dr. Newberry says; 
The country bordering the Rio Grande, in Chihuahua and Texas, 
is nearly destitute of trees, a feature which marks the aridity of the 
climate; yet, in certain localities, as on the bottom lands of the Rit^ 
Grande and Rio Concho, a vigorous and somewhat varied forest- 
growth was found at the advent of the whites. No better illustra- 
tion of the relation between the kind of vef]:etation and the water 
■ 
supply in a country can be found than that afforded by the luxuri- 
ant growth of trees of several kinds along the Cibola in the Chinati 
Mountains, Texas; while on all sides this oasis is surrounded by an 
apparently boundless grass-covered prairie, where the rain-fall is in- 
adequate for trees. On the mountain-summits, south of the V.10 
Grande is a sparse growth of pincn {Pinus edu/is) and evergreen oak 
(Quercus £morji,) The lowlands in certain localities, over thousands 
of acres, are thickly set with mesquite {ProsoJ>is g/audu/osa), here a
