dentibus brevissimis triangulari-ovatis acutis ciliato-serrulatis, legumine oblique obovato 

 1-spermo. (Tab. LXXIX.)— Hook, et Am. in Bot. Misc. 3. p. 180. 



This differs in no respect from the Chilian plant we described in our Contributions to the Botany of South 

 America. 



Tab. LXXIX. Fig. 1. Capitulum and involucre ; fig. 2. Single flower ; fig. 3. Legumen : — magnified. 



7. T. (Involucraria) melananthum ; procumbens elongatum glabrum, foliolis obovato- 

 cuneatis (stipulisque ovato-acuminatis rigidis) spinuloso-dentatis, pedunculis axillaribus 

 folio longioribus, involucris plano-haemisphasricis reticularis incisis spinulosis capitulo 

 denso brevioribus, calycis rigidi striati campanulati dentibus lato-subulatis spinescentibus 

 tubo longioribus corolla acuminata brevioribus integerrimis dernum reflexis, legumine 

 lato-elliptico dispermo membranaceo. — T. variegatum. (3. Torr. et Gr. Fl. I. p. 317 ? 



This comes very near T. Chilense, Hook, et Arn. supra, p. 16 ; but the stems are much taller, bearing 

 more copious heads of flowers, and the teeth of the calyx are quite entire. 



8. T. (Involucraria) obtusiflorum ; pubescens, caule elongato, foliolis obovato-lanceolatis 

 spinuloso-denticulatis, stipulis lanceolatis profunde inciso-spinosis, pedunculis axillaribus 

 folio duplo longioribus, involucris planiusculis parvis reticularis inciso-spinosis capitulo 

 laxiusculo majusculo triplo brevioribus, calycis dentibus subulato-spinosis integerrimis 

 longitudine tubi carina obtusa apice subdentata multo brevioribus, ovario oblique obovato 

 subdisperrno. Hook. Ic. PI. v. 3. t. 281. 



About a foot or more high, downy. Flowers large in proportion to the involucre. Corollas long, pale- 

 coloured, with a dark spot on the keel : the vexillum very blunt, and at the apex slightly toothed or jagged. 

 Aire very narrow, almost as long as the vexillum. 



9. T. (Involucraria) involucratum. Willd. (non Kunth). Smith in Rees' Cycl. — Hook. 



Fl. Bor. Am. 1. p. 133 T. tridentatum. Lindl. in Bot. Reg. sub fol. 1070 T. aciculare. 



Nutt. in Torr. et Gr. Fl. 1. p. 319. 



This is found in Chili as well as in California and N. W. America. — It varies considerably in size, from 

 six inches to a foot or more in height ; with its leaflets more or less narrow, sometimes obtuse, sometimes 

 quite acute. Segments of the calyx broad, with two (lateral) very short teeth and one long spinous one. 



10. T. (Involucraria) fimbriatum. — T. heterodon. Torr. et Gr. Fl. 1. p. 318. — «. foliolis 

 oblongo-ovalibus acutis, laciniis calycinis corolla duplo brevioribus omnino integerrimis. 

 — T. fimbriatum. Lindl. Bot. Reg. t. 1070. — [3. foliolis obovatis retusis. — y. foliolis obovatis 

 obtusis, calycis lacinia inferiore profunde trifida. — o. foliolis oblongis obtusiusculis, calycis 

 lacinia inferiore profunde trifida, reliquis bifidis vel integris, omnibus carinam sequantibus. 



This is a very variable species, or there are three distinct species in our collections. The original plant 

 of Lindley has short teeth to the calyx, and those quite entire ; and to this T. spinulosum, Dougl. in Fl. Bor. 

 Am. 1. p. 133, must be referred. Our /3., gathered in California by Mr Menzies, has obcordate leaves, but 

 it does not in other respects differ from Dr Lindley 's plant. Our two other vars., as we here consider them, 

 are in the present Californian collection, var. y. having the lower segment of the calyx always deeply 3-fid, 

 while our var. y. has larger paler-coloured flowers, longer teeth to the calyx, and those teeth, in the greater 

 number, bi- or trifid.
