terminal portion in the carpel, but the cell conforms to the solitary ovule 
and seed. This gives a Malvastriform section to Spheeralcea, and in our 
Rocky Mt. species, for example, Malvastrum coccineum retains its place, 
while Malvastrum Munroanum becomes Spheeralcea Munroana. Horsfor- 
dia is anew genus, between Spheralcea and Abutilon, of two species. 
H. alata is Sida alata of Watson, and H. Newberryi is Abutilon Newberryi 
of Bot. Calif. A new order, CHEIRANTHODENDRE, is established, con- 
taining the genera Cheiranthodendron and Fremontia. Bentham first 
placed these genera in Malvacez, but later trans‘erred them to Sterculia- 
cee. Dr. Gray thinks it better to recognize the peculiarities of these 
genera, of which the leading one is the strongly quincuncial calyx, and 
not to force them into an order of which a valvate calyx is an essential and 
substantially an unvaried character. New species of Mr. Pringle’s collect- 
pe are also described in addition to these under the heading “ Miscel- 
anea.”

The original of this new edition of Sach’s “ Text-book of Botany,” 
Book II, has been in the possession of botanists since 1882, but this most 
helpful translation puts it within the reach of all English speaking bot- 
anists. There has been considerable delay in its publication, as the revis- 
er’s preface is dated 1885, but it is none the less welcome. e chief 
thought of the book seems to be to “ make use of a consistent terminology 
ased upon homology,” a thing of great education al value, although there 
are some who may think it is not the best plan. For example, to call a 
pollen-grain a microspore may seem to be doing violence to a long estab- 
lished name, but when it is understood that the microspores of Phanero- 
gams are called pollen-grains, there can be no objection to using the latter 
name as a special group-name, and at the same time retain the idea of ho- 
mology. Objections of this kind are chiefly raised in the new terminology 
of Phanerogams, but the clear way in which this is stated, at the same 
time acknowledging the old names, can not be too highly commended. 
In fact, the whole treatment of Phanerogams is masterly, and is probably 
the most valuable contribution in the book, and should be carefully studied 
by every student of botany. The changes in the grouping of plants are 
known from the original German text, but it may be well to note them 
here Four great groups are recognized, viz., THALLOPHYTES, MUSCINEX, 
Vascutar CryprogamMs, and SEED-PLANTS or PHANEROGAMS. It would 
seem more uniform to call the three last groups Bryophytes, Pterido- 
phytes and Spermaphytes. Under Thallophytes five equivalent groups 
are recognized, which involves the greatest change from the original 
Stouping as given by Sachs. Myxom and Diatomacex are set apart as 
the first two groups, to which no serious objection will be made, unless
