ilie Herbarium of Professor Pallas. 263 



from Pallas's specimens sent to him from Berlin (above men- 

 tioned) to be the C/ianuerops humilh Linn., and that variety which 

 is said to grow twenty feet high. Willdcnow, in his Preface to 

 the Ilorlus Berolincnsis, also considers it to be that plant. Two 

 labels accompany the specimens, with the following inscriptions 

 on them : 



" Chamarops* arborea feminea. Palma nostra in H. R. Bero- 

 linensi culta, per foecundationem artificialem ab 111. Gleditsch 

 instituta, niaxime celebrata. 



" Soboles exinde ortae ad 3 pedum altitudinem fere accedentes 

 in eodem viridario aluntur sub matris umbra." 



A sketch from one of the specimens is annexed, Tab. VIII. 

 Whether the two supposed varieties may not be distinct species, 

 we must leave to those botanists who have an opportunity of ob- 

 serving them where they grow. 



On further examination of this Herbarium, I have found some 

 more new plants, and others but very little known, which I beg 

 leave to lay before the Society. The greater part of the plants 

 foupd by Sievers in his journey to discover the true Rhubarb, 

 and by him communicated to Pallas, are in this collection. One 

 of the most remarkable is the Robinia juhata, first published in 

 the Is! ova Acta Academice Sclent iariun Imperialis PetropoUtaiKE ; 

 also more perfect specimens of the same sent by the Governor of 

 Irkutsk at Pallas's request, and from which the superb figure in 

 Pallas's Species Astragalorum, tab. 85, was taken : these are nearly 

 three feet in length, and in excellent preservation. Rheum nutans, 

 sibiricum and caspicum also of the Flora Rossica, vol. 2, quoted 



* "Chamaerops No. 4. Chamaer. arborea feminea. L. p. 1657."
