Abstract: Twelve specimens from the West lndies, collected by<br />
0.p. Swartz, have been discovered in the herbarium at Gdteborg.<br />
The collection comprises n j.ne isotypes, v iz . Baeomyces l-g!99ides<br />
(Sw. ) Ach., Leptogium diaphanum (Sw. ) Mont., L. marginelJ-<br />
um (Sw.) S.F. Gray, Lobaria dissecta (Sw.) Raeuschel, Parmel-ieIJa<br />
pannosa (Sw.) NUff. Arg., Stereocaul,on ramulosum (Sw.).<br />
Raeuschel, Sticta damaecornis (5w. ) Ach., Sticta l,aciniata (5w. )<br />
and S. tomentosa (Sw. ) Rcn. The material is briefly discussed.<br />
The main part of the lichen colLection by 0.p. swartz (rz5o-t8t8),<br />
is located. in Riksrnuseum, stockholm (s), with subord-inate maierial<br />
in UpS. In addition, varj-ous duplicates are also for:nd in BM-ACE,<br />
C, G, and H-ACH.<br />
In the Botanical Museum at Gbteborg (Cf)' f have encoulltered 12<br />
specimens which appears to be original collections by swartz from<br />
his voya€e to the West Ind.ies and. northern South America 1784-86.<br />
Nine of these lichens veqy 1ike1y constitute isotypes of species<br />
d.escribed. by Swartz in ,,Nova Genera & Species Plantal:tmtr (tl8g).<br />
The material 1s sparse, consisting of only one or two thalli of<br />
each species, grued on old-fashioned paper. Anrrotations are in black<br />
ink a'd. mention the ,,Lichenrr-11emsr' "J*rricatt (o" in one case 't'Dominica,,),<br />
and ,,Dr. Swartzr' (fig. 1 ). There is some uncertainty of the<br />
hand.-rgiting, and later scientists have made some comments on slips '<br />
G.O. Malme says that the hand. is not unlike that of swartz, but more<br />
neat. The titl-e of ,rDr. ,, before swart z'name also casts suspici-On On<br />
i-ts authenticity. O. c,ertz states that the hand.-r^rriting j-s not found<br />
in letters by swartz. The specimens are preserved in modern packets<br />
with G3 herbarium labels. Of special interest here is an explanation<br />
in the ha'd of A.I[. Magnusson: "From the lichen corlection of Dr-<br />
Westring through lagnan C-J. Ergelblon, 18rr"'<br />
