this volume, are devoted to the order Composite, which is elaborated by 
Prof. Harvey. Aster is here pretty largely represented, the genus being, 
as T'ripolium, (There ought now, therefore, to be no question about the 
admissibility of the Polynesian Agdtea of the Violet Family, which has 
been thought to be in pronunciation too like Agathe/a.) The price of 
the volume has been raised from twelve to eighteen shillings, which is 
still very reasonable. A. G. 
hesaurus Capensis, by Prof. Harvey, the excellent companion of 
the above Flora, has reached the two-hundredt plate, completing the 
second volume. The most interesting plant figured in the last fasciculus 
is Hydnora triceps, illustrated upon a double plate. A. G. 
4. Ammobroma Sonore (literally, the Sand-food of Sonora) is the 
name of an extraordinary root-parasitic plant, of the region at the head 
of the Gulf of California, which Dr. Torrey has just described and figured 
as a new genus, allied to the rare Mexican Corallophyllum of Kun 
(or Lennoa, Lexarza), and still more to the Californian and hardly better- 
known Pholisma of Nuttal. It hardly throws any new light upon the 
affinity of these strange plants, which, though justly thought to be rather 
Monotropaceous than Orobanchaceous, are still obscure. This plant, 
growing in a forlorn sandy desert, almost covered by the sand in which 
it lives, was found by its discoverer, the late Col. A. B. Gray. to form a 
trict, and is said to be very luscious when first gather re-

just issued, concludes the enumeration of the Phanerogamous species 
published from 1851 to 1855 inclusive, and carries down to the letter © 
the alphabetical index of these three volumes. The remainder of the 
index will occupy fasc. 8 of this bulky volume, which began to be issued 
in 18 The accumulation of species published within the last 10 years 
(since 1855) is perhaps equally large; and, if treated in the same way, 
eir enumeration may be completed in the year 1875. It is to be re 
gretted that the compacter plan, adopted in the earlier volumes of the 
series, was not red to. ‘ A.
