It was a “plant coming from dry places in Egypt” [nascitur in Aegypti locis siccis & squalidis] with “flores albi, sclareae seu herbas Sancti Ioannis floribus quam simili”.There isalso mention of itspharmaceutical properties,Alpino being particularly interestedinthemedicinalpropertiesofplants.ThereferencetoStJohnisofspecialinterestin that“erbaSanGiovanni”isoneoftheItaliancommonnamesforSalviasclareaL.,aspeciesof- tenconfusedwithS.tingitana.ThereasonforconsideringAlpino’splanttobethesameasS.tin- gitana, stems from Lamarck (1805: 600) who listed the name [as “an marum agyptiacum?”] amongthesynonymsofhisS.foetida(=S.tingitana).

TheinitialvaliddescriptionofSalviatingitanawasmadebyEtlinger(1777)inhisCommen- tatio Botanico-Medica de Salvia.He gave a brief description of S.tingitana and cited two pre- Linnaean elements: Tournefort (1700) and Rivinus’ illustration (Rivinus 1690: t. 62). Etlinger referredtothelatteras“bon.sedmalespinascalycisneglexitsculptor”,thusconsideringittobe a good likeness except for the calyx spines not agreeing with his own description “spinosis sulcatis”.Itshabitatwasgivenas“inAfrica”.Healsocommented“foliaS.disermas,sedlatiora, acuta”and“verticilli,bracteaeetcalycesS.spinosae,sedhibrevioresadlimbumusqueprofundius sulcati,breviusmucronati”.AlthoughEtlingermadenoreferenceheretotheearlierpublications ofArduinoortoAllioni,helistedthemas“synonyms”ofS.disermasonthefollowingpage.

Willdenowia38–2008 47 Fromaroundtheturnoftheeighteenthcentury,Salviatingitanabecamereferredtomorefre- quently. Willdenow (1797: 147) had seen the living plant (as “v.v.”), presumably at the Berlin Botanic Garden, and considered that it was very similar to S. spinosa but had a woody stem, cordate,erose-dentate,rugoseleaves,ciliatebracts,andthattheplantwasveryfoetidandcame from“Africa”.Sadly,thereisnocomplementaryspecimeninhisherbarium(B-W).Desfontaines (1798:24),inhisFloraAtlanticacitedS.foetidaLam.:"totaplantaodoremgravissimumspirat. Habitat in agro Tunetano" and gave the symbol for a shrub. There is a good specimen in Desfontaines’ herbarium in P-Desf. and it is probably correct to assume that the specimen had beencultivatedinParisattheJardinduRoi,thenalready,duetotheFrenchRevolutionrenam- ing,theJardindesPlantes. Lamarck(1805:600)againlisted“Salviafetida[sic]Lam.”(i.e.S.tingitana)withfullsyn- onymy,descriptionandnotes:“CetteespèceadesraportsavecleSalviasclareaparlagrandeur, laformedelesfeuilles,lalargeurdesesbractées,&danstoutsonensemble.Cetteplantecrôit naturellentdansleLevantetenBarbarie.OnlacultivéauJardindesPlantesdeParis[withsym- bolforshrub]v.v.”Asmentionedatthestartofthissection,Lamarckcitedamongthesynonyms alsoAlpino'snameas“AnmarumagyptiacumAlp.?” FurtherreferencestoSalviatingitanaaboutthistimeincludePersoon(1805:28,no.82),who recordeditforNAfricaandnoteditaspossessingafoetidodour.HealsolistedS.foetidaDesf.

The latter, S. coarctata, Vahl related to S. argentea L., a species surely distant from S. tingitana.EventhoughBentham(1832-36)hadpreviouslyconsideredS.coarctatatobeasyn- onymofS.tingitana,thecorresponding,farfromideal,specimenintheVahlherbariuminCis notatalllikeS.tingitanabutmoresimilartotheEMediterraneanS.palaestina.Later,Bentham (1848)inhisdiscussionaboutS.argenteaalsonotedsomesimilaritieswithS.tingitana. Vahl (1804-05) also added another species name that comes into the convoluted history of Salviatingitana.InhiscommentsonLinnaeus’S.disermas,hewrote“AnS.disermasLin.Mant. 318.eademacS.tingitanaEtling?”S.disermas hasalsobeenmisappliedanditsdistributionva- riouslygivenasSyria,Greece,Byzantium [Istanbul].The meaningofthe epithet,whichmight giveaclueastotheidentityofthespecies,isalsouncertain:Donn&Don(1845:19)equatedit with"long-spiked",butitisprobablethatthisinterpretationwasbasedontheknowledgeofthe plant rather than on its correct etymology. Apparently it was Bentham (1832-36) who first pointed out that S. disermas based on the specimen no. 42.26 in the Linnaean herbarium (at LINN) was in fact not from the Mediterranean region but a native of southern Africa (Hedge 1974).AnotherspecimenlabelledasS.disermasintheLinnaeanherbarium(no.42.27atLINN) is certainly wrongly named. It was later annotated as “non disermas” by J. E. Smith (Savage 1945: 5). The specimen has “Ard.” (= Arduino) hand-written in small letters at its side (see above);inouropinion,itisS.tingitanaandnotS.disermasaslistedbyWilliams(1890). Other authors about this time who briefly referred to Salvia tingitana or S. foetida include Willdenow (1809: 42), Candolle (1813) and Desfontaines (1815: 67). Bentham (1832-36: 225, 718) related S.tingitana (S.foetida and S.coarctata) “in Afr.Bor.Agro Tunet.” toS.spinosa.

Possibly,itwasinthePaduaBotanicalGardenintheearly1600s(Alpino1627,1640)andproba- bly in the same garden in the 1750s (Arduino 1759) and also at that of Turin (Allioni 1774). Arduino (1759), one time curator (acting prefect, 1757-60) of the garden at Padua, said of this plant“ThistypeofSalviaisnotanativeanditscountryoforiginisuncertain.Fourorfiveyears agoitappearedandgrewfromimportedseedsinthegardenatPadua.Ihavebeenunabletofind adrawingofitoradescriptionanywhere,althoughIhaveassiduouslyconsultedmanyprominent botanicalwriters.Forthisreason,IhavedecidedtorecorditasanewtypeofSalvia;itseemedto merittheattentionofallwhostudybotany.Thewholeplantisviscid,piloseandsweetsmelling ...”.[PeregrinaesthaecSalviaespecies,dequeejuspatriacertinihilaffirmarepossum.Quatuor vel quinque ab hinc annis, e seminibus peregrinis in Horto Patavino nata est atque alta.

His catalogue gives a clear picture of the wealth of plants then cultivated. Bearing in mindthatLinnaeusin1753inSpeciesPlantarumdealtwithanoveralltotalof27speciesofSal- via, only 24 years later the Jardin du Roi was growing no fewer than 41 species. The garden, surely one of the richest in Europe at the time, was laid out in 1776 according to the system of BernarddeJussieuandnotofthatofTournefortorLinnaeus.InBlaikie’slistofSalvias,thespe- cieslistedaremostlysuffixedwithabbreviationsoftheirdescribingauthors,themajorityofthese being“L.”,i.e.Linnaeus.Thereisalsoasmallnumberwiththesuffix“j”,presumablyreferringto deJussieu,suchas“S.coccineaj”,“S.praecoxj”,“S.nubiaj”,and“S.amplexicaulisj”.Theim- plication is that these were recognised as new but as yet undescribed species.

Salviatingitana’srelationto,orconfusionwith,otherspecies A surprising number of species have been considered to be close allies of Salvia tingitana, or have been confused with it, since it was described over 230 years ago. Etlinger (1777: xxxv), Willdenow(1797:147)andBentham(1832-36:225,1848:282)allcommentedonthesimilari- ties between S. spinosa and S. tingitana.
