CREPIS XUDICAULIS L. AXD LEOXTOBON HIRTUS L. 103 



got misplaced by some accident, for it says " Scorzonera macro- 

 cephala DC," an impossible determination for him to have suggested. 

 Scorzoriera macrocephala, DC. Prodr. vii. p. 122 (1838) is defined 

 " glabra, fol. confertis sessilibus linearibus .... capitulum 2 poll, 

 longuin, pollicem et ultra latum." 



To go into farther detail as to these four specimens, they are : 



(1) A small and unmistakable example of L. Villarsii received 

 from AUioni, on which Linnieus has written '■'■ hirtum^^ and "All." 

 and a teryo " Hieracium parvum hirsutum, caule aphyllo, ci-assmn ubi 

 siccatum. J. B. Allion. distinguendum ab Hieracio caule aphyllo 

 hirsutum J. B. Est C. B. prodr. diversum ab liispido pilis indivisis, 

 calyce glabro " and " ex agro nicensi." 



This sheet also bears " hirtum D. Afzel." in Smith's hand and 

 the impossible label of Schultz' above referred to. 



(2) An undoubted piece of Thrincia liirta Roth, without any 

 writing of Linnaeus' and sine loco. To this also Smith has wa-itten 

 " hirtum D. AfzeL" and Schultz has ticketed " Thrincia liirta 

 Roth." 



(3) A luxuriant specimen of L. Villarsii grown in Hort. Upsala, 

 to which Linmeus has written "H. U." and " A«6rj9«'</?«/«," cancelled 

 and corrected to ^^ hirtum,'' then a tergo " cujus pili non apice 

 stellatii" Smith has again added " hirtum D. Afzel," and Schultz 

 has ticketed "X. Villarsii.'''' 



(4) A small example of Leontodon pyrenaicus Gouan, 111. p. 55, 

 tab. 22. figs. 1 & 2 (1773) = P/cm- saxatilis All Fed. i. jx 211, 

 tab. 14. fig. 4. This bears no writing of Linnajus except "Alb," 

 showing that it came from Allioni. The label in Allioni's hand 

 gimamed to the sheet says " Taraxacum foliis integris dentatis, calyce 

 hispido, pappo plumoso Hall.," which is one of the synonyms quoted 

 by him for his Picris saxatilis. There is no writing of Smith's on 

 this sheet. Schultz has ticketed it " Leontodon pyrenaicusC 



This is surely enough to establish the identity of L. hirtus L. 

 with L. Villarsii. The possibility of taking it for Thrincia hirta 

 seems due to the mistake having already occm-red before the pubH 

 cation of the Linnean name. Dillenius, Cat. PL Giss. p. 114 (1719), 

 fancied that he had found C. Bauhin's Hieracium Dentis leonis folio 

 Jiirsutie asperum minus at Giessen, " ad molendinum parvum," and 

 Buxbaum, Enum. PI. Hall. p. 96 (1724), quotes Hieracium parvum 

 hirsutum, caule aphyllo, crispum ubi siccatum J. B. (with Tourne- 

 fort's synonym also) for the fields near Halle. In both cases the 

 plant must have been thrincia hirta, ex loco, and the old Bauhin 

 names are wrongly d)-agged in. 



When Leysser wrote hh Flora Halensis- (17(51) Leontodon hirtus 

 had made its a])pearance in Sj'st. Nat. x. (1759) with a reference to 

 Sp. PI. i. p. 799, which brought in a.s sj^nonymous the very Bauhin 

 name that Buxbaum had ([uoted, so he not unnaturally (p. 145) 

 referred the Halle plant to the Linnean species, as jet very meagrely 

 described. So far we have nothing but the north German iiabitat to 

 identify the plant of these three authors with Thrincia hirta, but 

 the characters assigned to L. hirtus by Leers, Fl. Herborn. p. 168 

 (1775), are those of T. hirta: "corollulae lividse, demura flavaj " 

 and " semen corollae extimje cah'culo bi-evi loco pappi coronatum."
