. Mr. LamBert’s Account of the Herbarium of Professor Pallas. 257 
sent to Pallas fine specimens of all the plants gathered during 
his voyage with Cook. I find several species here not in his own 
Herbarium, which I purchased some years ago from his father- 
in-law Professor Heyne. 
All the plants collected in Billing's expedition, by Dr. Merke, 
the naturalist employed in that voyage, and others, appear to be 
here; but I have not been able to find among them a celebrated 
plant mentioned by Sauer in his account of that expedition, and 
called there Zemlenoi Laudon, or frankincense of the earth, (see 
page 28,) unless it be Cachrys odontalgica. Sir Joseph Danks sent 
Pallas a fine collection of specimens, which were collected by him 
and Dr. Solander in their celebrated voyage with Captain Cook. 
There are also a great number of species from Professor Thunberg, 
and Grecian plants from the late much lamented Dr. Sibthorp. 
Among these is the true Hellebore of the ancients, found by him 
on mount Olympus, the Helleborus officinalis of Dr. Smith's Pro- . 
dromus Flore Grece. 1 find also many plants of the Flora Au- 
striaca from Jacquin, and several of Forskahl’s, communicated 
by Vahl. Cavanilles appears to have sent to Pallas many plants 
from Spain. Here is also a curious collection from Persia, made 
chiefly in the neighbourhood of Gilan by Gmelin; and in it I ob- 
serve the Ferula assafatida, but without fructification. There are 
many specimens of Russian plants from Gmelin, Georgi, and 
others, all named and numbered according to their works, and 
having synonyms of the older authors prefixed : also from Steller, 
with names and numbers from his unpublished Flora Ochotensis 
and other MS. works mentioned by Pallas in the prefate to his 
Flora Rossica. — — s
