THE CONYZAS OF MILLER's DICTIONARY (ed. 8). 63 



Hoastoun's unpublished drawings (p. 46) under the name " Conyza 

 scandens." 



It seems right to say that a descriptive label in Houstoun's 

 hand identical with Philip Miller's phrase (save in the substitution 

 of "Conyza" for "Jacea") — a substitution explained by Hous- 

 toun's phrase in his MSS., " inter Conyzam et Jaceam videtur 

 ambigere " — is attached in Herb. Banks to another Vera Cruz 

 Vernonia, not far removed from V. scorpioides. This plant, how- 

 ever, does not agree with Linnaeus' or Houstoun's description, and 

 the label has no doubt been misplaced. A specimen from Houstoun 

 with his descriptive phrase is found, as has already been stated, in 

 Herb. Sloane ccxcii, f. 65, " ex Vera Cruce." 



Conyza spicata Mill. Diet. no. 14= Baccharis rhexioides H. B.K. 

 Dryander has marked through Miller's name on Houstoun's speci- 

 men (from Carthagena) in Herb. Banks, and has substituted 

 '^ trinervia^' — a name by which, under another genus, specimens 

 of B. rhexioides collected by Banks and Solander at Kio Janeiro in 

 1768 are described in Solander's MSS. William Wood (in Rees's 

 CyclopcBdia) gave Miller's plant a new trivial name — cartliagenensis 

 — which is not included in the Index Kewensis. 



Conyza symphytifolia Mill. Diet. no. 10 = Phichea odorata Cass. 

 Houstoun's descriptive phrase — '* Conyza Symphyti folio flore luteo " 

 — is attached to his specimen from Vera Cruz in Herb. Banks. A 

 note on the synonymy of Pluchea odorata will be found at the end 

 of this paper. 



Conyza tomentosus (tomeiitosis) Mill. Diet. no. 5 = Vernonia 

 Beppeana Less. Houstoun's specimen from Vera Cruz in Herb. 

 Banks has his MS. descriptive phrase cited by Miller, /. c. There 

 is another Houstoun specimen in Herb. Sloane ccxcii, 67. 



Conyza trinervius {trinerviis) Mill. Diet. no. 12 = Baccharis 

 rhexioides H. B. K. Miller's specimen from Carthagena (Robert 

 Millar) bears his descriptive phrase in his own hand. 



Conyza uniflora Mill. Diet. no. lQ=yer7ionia remotiflora Rich. 

 The specimen from Herb. Miller bears his descriptive phrase ; it is 

 not localized, but was sent (according to the Dictionary) from 

 Carthagena by Robert Millar. It was also found by Houstoun, as 

 Miller cites it from his MSS. 



Conyza viscosa Mill. Diet. no. 8 (1768) = (7. lyrataB.. B. K. Nov. 

 Gen. iv. 70 (1820). This is perhaps the most interesting of Miller's 

 species, and is the only one which remains in Conyza, if that name 

 is to be retained for the genus.* Mr. Hiern has kindly examined 

 the various specimens of C. lyrata in the Kew Herbarium, and we 

 have compared Miller's plant with those in the British Museum ; 

 and there can be little doubt but that the two species are identical. 

 We have Houstoun's specimens (from Vera Cruz, 1730) bearing his 

 descriptive phrase, and in Herb. Sloane ccxcii, 67 ; and also a full 



* Mr. Hiern is of opinion that the name Conyza cannot be retained, and 

 that Marsea of Adanson (Fam. ii. 122 (1763) ) must take its place. In that case 

 the plant under consideration will stand as Marsea viscosa.
