is therefore probable that tlie species vvitli a neuter ray 

 oiiglu to be referred to Coreopsis, or that Sitnsia ought again, 

 as Cassine and De Candolle suggest, to be restored for 

 them. 



1153. (1.) Spiianthes (Salivaria) Macrcei (H. & A.); 

 stolonifera, foliis lineari-spathulatis obtusiusculis sessilibus 

 utrinque glabris vel pilis brevibus raris adspersis versus basin 

 ciliatis, pedunculo foHis vix duplo longiore piUs brevibus plus 

 minusve adsperso, involucri foliolis ovalibus interioribus apice 

 erosis, radio nullo, disco hemispherico — S. leiocarpa, DC. 

 Prodr.5.p. 626? — Conception, Chili ; Macrae. — S. leiocarpa, 

 DC. agrees tolerably well with this, and it is also a plant of 

 Macrae ; biit>as stated by De Candolle. discovered "ad Sinum 

 Chorillo in Peru," whereas ours is from Chili. 



1154. (2.) S. (Salivaria) pusilla, (H. & A.) ; repens, foliis 

 spathuliito-linearibus obtusiusculis basi in petiolum attenuatis 

 glaberrimis, pedunculo foliis duplo longiore versus apicem 

 subpubescente, involucri foliolis late ovalibus margine scari- 

 osis minute fimbriatis, radio nullo. — Road-sides about Bue- 

 nos Ayres ; Dr Gillies. Banda Orientale; Tweedie. 



1 155.(3.) S. (Acmella) he/enioides, (H.& A.); erecta glabra, 

 foliis cblongis lineari-lanceolatis linearibusve calloso-apicu- 

 latis basi attenuatis integerrimis vel utrinque sub-dentatis, 

 pedunculis valde elongatis, radii flosculis patenti-recurvis 

 apice ti ifidis disco subcylindrico longioribus. — Mendoza and 

 Buenos Ayres; Dr Gillies. Uraguay and Rio Grande; 

 Tweedie, {n. 864, 858, and 867.) 



1156, (4.) S. (Acmella) affinis, (H. & A.); decumbens, 

 caule glabro, foliis linearibus utrinque attenuatis calloso- 

 apiculatis hinc inde calloso-denticulatis, pedunculis elongatis 

 versus apicem dense pubescentibus, flosculis radii discum 

 conicum subsequantibus obtuse tridentatis. — Los Loamos in 

 N. PataiJ^onia; Tweedie {in Herb. Am.) — Very nearly allied to 

 S. stenophylla, and to S. helenioides, but the florets of the ray 

 are only toothed, not trifid.
