dentibus brevissimis triangulari-ovatis acutis ciliato-serrulatis, legumine oblique obovato
1-spermo. (T ab. L X X IX . )—Hook, et Arn. in Bot. M ise. 3. p . 180.
This differs in no respect from the Chilian plant we described in our Contributions to the Botany o f South
America.
T ab. LXX IX. Fig. 1. Capitulum and involucre ; fig . 2. Single flower; fig . 3. Legumen:—magnified.
7. T . (Involucraría) melananthum ; procumbens elongatum glabrum, foliolis obovato-
cuneatis (stipulisque ovato-acuminatis rigidis) spinuloso-dentatis, pedunculis axillaribus

tubo longioribus corolla acuminata brevioribus integerrimis dernum reflexis, legumine
lato-elliptico dispermo membranaceo.— T . variegatum. fi. Torr. et Gr. Fl. l . p . 317 ?
This comes very near T. Chilense, Hook, et Am. supra, p. 16 ; but the stems are much taller, bearing
more copious heads of flowers, and tbe teeth of the calyx are quite entire.
8. T . (Involucraría) obtusifiorum; pubescens, caule elongato, foliolis obovato-lanceolatis
spinuloso-denticulatis, stipulis lanceolatis profunde inciso-spinosis, pedunculis axillaribus
folio duplo longioribus, involucris planiusculis parvis reticulatis inciso-spinosis capitulo
laxiusculo raajusculo trip lo brevioribus, calycis dentibus subulato-spinosis integerrimis
longitudine tubi carina obtusa apice su bdentata m ulto brevioribus, ovario oblique obovato
subdispermo. Hooh. Ic. P L 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.
Alæ very narrow, almost as long as the vexillum.

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.

This is a very variable speeies, 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 . spinidosum, Dougl. in Fl. Bor.
Am. I. p. 133, must be referred. Our fi., 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, bU or trifid.
