here described for which this herbarium is alone authentic ; 
for Linnzus, as we have already remarked, possessed very 
few of Clayton’s plants. The collection is nearly complete, 
but the specimens were not well prepared, and are not there- 
fore always in perfect preservation. A collection of Cates- 
by’s plants exists also in the British Museum, but probably 
the larger portion remains at Oxford. There is_ besides, 
among the separate collections, a small but very interesting 
parcel selected by the elder Bartram, from his collection 
made in Georgia and Florida almost a century ago, and pre- 
sented to Queen Charlotte, with a letter of touching simplic- 
ity. At the time this fasciculus was prepared, nearly all the 
plants it comprised were undescribed, and many were of en- 
tirely new genera; several, indeed, have only been published 
very recently, and a few are not yet recorded as natives of 
North America. Among the latter we may mention Petive- 
ria alliacea and Ximinea Americana, which last has again 
recently been collected in the same region. This small parcel 
contains the Elliottia, Muhl., Polypteris, Nutt., Baldwinia, 
Nutt., Macranthera, Torr., Glottidium, Mayaca, Chaptalia, 
Befaria, Hriogonum tomentosum, Polygonum polygamum, 
Vent., Gardoquia Hookeri, Benth., Satureia (Pycnothymus) 
rigida, Cliftonia, Hypericum aureum, Galactia Elliottii, 
Krameria lanceolata, Torr., Waldsteinia ( Comaropsis) lo- 
bata, Torr. & Gr., the Dolichos ? multiflorus, Torr. & Gr., 
the Chapmannia, Torr. & Gr., Psoralea Lupinellus, and others 
of almost equal interest or rarity, which it is much to be re- 
gretted were not long ago made known from Bartram’s dis- 
coveries. 
The herbarium of Sir Joseph Banks, now in the British 
Museun, is probably the oldest one prepared in the manner 
commonly adopted in England, of which, therefore, it may 
serve asa specimen. The plants are glued fast to half-sheets 
of very thick and firm white paper of excellent quality (simi- 
lar to that employed for merchants’ ledgers, etc.), all care- 
legit.” Ludg. Bat. 8vo, 1743. Ed. 2, 4to, 1762. The first edition is cited 
in the “Species Plantarum” of Linnzus ; the second, again, quotes the 
specific phrases of Linnzus.
