52 THE CONYZAS OF MILLEr's DICTIONARY (ED. 8). 



dolle's Monosis tarchmantliifolia, but, in the absence of the type or 

 other material, has added an expression of doubt. I think there is 

 httle doubt as to the correctness of the identification, although it 

 may be safer to retain the query. Houstoun's specimen in Herb. 

 Banks (sent from Vera Cruz in 1731) bears the MS. description 

 cited by Miller ; there is another specimen from Houstoun in Herb. 

 Sloane ccxcii. 64. 



CoNYZA PEDUNCULATA Mill. Dict. no. 15. Miller's specimen of 

 this is very poor ; it is a Baccharis, probably a somewhat abnormal 

 form of B. rhcxioides H.B. K. It was grown in Chelsea Garden 

 from seeds sent from Campeachy by Robert Millar. 



CoNYZA SALiciFOLius Mill. Dict. 110. 6 = Pluchea suhdecurrens 

 Cass. ? This was identified by Mr. Bennett with an expression of 

 doubt similar to that which he expressed as to G. conjmbosa. As in 

 that case, the identification is probably correct, but it is safer to 

 retain the query. The specimen in Herb. Banks is from Houstoun 

 (Vera Cruz, 1731), and bears his descriptive phrase ; another 

 example from him is in Herb. Sloane, ccxcii, 67. 



CoNYZA scandens Mill. Dict. no. 11 = Vernonia Schiedeana Less. 

 Of this we have Miller's specimen from Houstoun (Vera Cruz) in 

 Herb. Banks, and another example from Houstoun in Herb. Sloane 

 ccxcii, 65. On the Banksian specimen is a note in Dryander's 

 hand identifying Miller's plant v/ith C. tortiwsa L., followed by a 

 note : " See Herb. Cliffort., where the specimen described by Linne 

 is from Miller." The specimen in question is now (like the rest of 

 the plants of the HorLus Cliffortianiwi) incorporated in the National 

 Herbarium, and is undoubtedly identical with the plant from Herb. 

 Miller. G. tortiDsa has always been obscure — "species mihi 

 omnino obscura!" says DeCandolle, who places it among his 

 " Conyz^ auctorum non satis not^ pler^que verisimiliter e genere 

 excludendffi" ; and it may be worth while to clear up its hibtory so 

 far as the material at our disposal will permit. 



Gonyza tortuosa (Linn. Hort. Cliff, p. 405) is founded on two 

 plants. The first is cited from " Vaill. Act. 1719, p. 396"—?'.^. 

 Hist. Acad. Sciences, 1719 (Paris, 1721), p. 300 (396 is a misprint). 

 Vaillant's descriptive phrase runs, "Conyza madagascariensis, fruti- 

 cosa, tortuoso caule, Corni folio. Tsi-mandats, Flacourt, Hist. 133, 

 no. 71 " (1661). Flacourt gives no description, and the small 

 figure on the folding plate facing page 144 (bearing the same 

 number) apparently supplied the material for Vaillant's descriptive 

 phrase. This plant must therefore remain obscure. 



The second plant, from which Linnaeus drew up his description, 

 was sent him by Philip Miller. The type-specimen in the British 

 Museum Herbarium, already referred to, is named in Miller's hand 

 " Jacea Americana scandens lauri folio scabro floribus spicatis albis 

 Houst. Vera Cruz." Houstoun gives a full description of the 

 plant under this name in his " Plant^e circa Veram Crucem obser- 

 vatse " (Houstoun MSS. p. 373), and a specimen from him in Herb. 

 Banks (from Herb. Miller) agrees entirely with the Hort. CUffort. 

 plant. There is a sketch of the same plant in the volume of
