floral organs are not unfrequent among Dicotyledons, but here we 
have the arrangement diversified by the decussation more or less 
invading the flowers, or by the irregular imbrication descending into 
the bracts, besides great diversity in the mode of imbrication or 
superposition of the floral parts. The number, position, and structure 
of the stamens present in the large and very natural genus Glusia 
discrepancies, which would, we believe, in scarcely any other instance 
be admitted as of anything less than generic value. The two oppo¬ 
site positions of the raphe, ventral or dorsal (with the ovule in 
both cases pendulous), which many modern botanists, especially 
those of the organogenic school, consider as absolute ordinal 
characters, are here exemplified in two monotypic genera, Pilosperma 
and Helvetia , scarcely distinguished from each other in any other 
particular. The diversities in the fruit of Guttiferse and the much- 
discussed question of the integuments of the seed are also entered 
upon by Messrs. Planchon and Triana, as well as the little that is 
known on its germination. But the latter portion of the Memoir 
appears to have been cut short, in order to enable the authors to 
resume the Prodromus of the JSTew Grenada flora, which is also the 
reason alleged for deferring, for the present, the intended third part 
of the Memoir, treating of the geographical distribution, affinities, 
and economic application of Guttiferse. It is to be hoped, however, 
that circumstances may ere long enable Dr. Planchon at least to 
publish the remainder of his observations on this most interesting 
Order, which cannot fail to be a valuable contribution to science. 
XL.— Botany oe the Journey oe H.B.H. Prince Waldemar 
of Prussia (Die Botanischen Ergebnisse, &c.). The Plants 
collected by Dr. Werner Hoffmeister, Physician to H.B.H. in 
Ceylon, the Himalaya, and on the borders of Tibet, and described 
by Dr. P. Klotzsch, and Dr. Aug. Garcke. With 100 litho¬ 
graphed plates. Berlin, 1862. 1 vol. 4to. 
Dr. Hoeemeister was attached as physician to the suite of Prince 
Waldemar of Prussia, who made a tour through British India in the 
year 1845. The party visited Ceylon, proceeded to Calcutta, and 
thence to Nipal, where, as usual, the narrow and exclusive policy of 
the authorities, debarred all access to the interior of the country, and 
restricted them to the neighbourhood of the Valley of Katmandu, 
the capital. Erom Nipal they proceeded to Kami Tal, in Kumaon, 
from which place their Plimalayan travels may, in fact, be said to 
have begun. Prom Naini Tal they struck into the mountains in a 
N.W. direction, crossing in succession the lofty mountain ranges, 
which separate from each other different tributaries of the Ganges, 
gradually increasing their elevation as they came nearer to the 
snowy mountains. After a visit to Gangutri, near which place the
