the Herbarium of Professor Pallas. 263 
from Pallas’s specimens sent to him from Berlin (above men- 
tioned) to be the Chamerops humilis Linn., and that variety which 
is said to grow twenty feet high. Willdenow, in his Preface to 
the Horius Berolinensis, also considers it to be that plant. 'Pwo 
Jabels accompany the ge with the following inscriptions 
on them: 
* Chamerops* lf boren feminea. Palma nostra in H. R. Bero- 
linensi culta, per foecundationem artificialem ab lll. Gleditsch 
instituta, maxime celebrata. | 
* Soboles exinde ortz 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. 
Own 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 
found by Sievers in his journey to.discover the true Rhubarb, 
and by him communicatéd to Pallas, are in this collection. One 
of the most remarkable is the Robinia jubata, first published in 
the Nova. Acta Academie Scientiarum | Imperialis Petropolitane ; 
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 
* «c Chameerops No. 4. Chamer. arborea feminea, L. p. 1657.”
