species. Of Moluccella grandiflora of the Species Plantarum by 
Willdenow, which is M. diacanthophylla of Pallas in Nov. Act. 
Petrop. vol. x. page 380, table 11, the very specimens from | 
which the figures seem to have been made, are named in his MS. 
Moluccella quadrangularis, species nova e deserto Buscarico. A plant 
which he describes in the Appendix to his Travels as Planta 
Salsa, &c., and supposes it to be a Cacalia, I have not been 
able to discover as yet, unless he has placed it in another genus, 
which is most likely, or that somebody is more fortunate than 
myself in the possession of it. Lamarck observes in the preface 
to Pallas's Travels, that he mentions the same plants repeatedly, | 
even the most common ones,—which certainly is sometimes the 
case; because, perhaps, he thought that they would be better 
understood by the generality of his readers, and did not like to 
give details of new species there, which he intended to publish 
ina work devoted to that purpose. As I am preparing to givea 
catalogue of all the species found in his Herbarium, with the ob- 
servations I there find in MS., I. shall now only submit to the 
Society an account of some of the most remarkable species that 
I have already noticed ; and express a. hope that in future every 
botanist sent on similar expeditions may execute his charge with 
as much assiduity as Pallas has done, and bring us home as ex- 
tensive collections. ~
