6 PITTONIA. 
longipes, var. latifolium of the Botany of California, but has 
characters not credited to that. 
T. EXILE. Near T. Palmeri and of the same erect-spread- 
ing, freely branching habit: about three inches high: leaflets 
cuneate-obovate, emarginate, or obcordate, mucronulate, den- 
ticulate, the largest hardly more than 2 lines long: stipules 
lanceolate, acuminate, entire: umbels axillary, short-pedi- 
celled, 5—12-flowered: calyx-tube short-campanulate, half as 
long as the subequal, triangular-lanceolate, aristate-pointed, 
searious-margined teeth: corolla flesh-purple, exceeding the 
calyx: legume exserted, 2-seeded. 
Island of Santa Cruz, 1886. 
T. DEPAUPERATUM, Desv.? Size and habit of T. amplectens, 
the heads as few-flowered: involucre nearly obsolete, appear- 
ing under the head as a more or less scarious, entire rim : 
corolla oval in age, somewhat feather-veined, about half filled 
(lengthwise) by the long-stipitate, 1—2-seeded pod. 
Species not as common in California as T. amplectens and 
of somewhat doubtful identity with the South American plant, 
which has together with a firmer texture (brittle when dry) 
more herbaceous stipules and calyx, the teeth of the latter 
less unequal, and longer, nearly equalling the young flowers. 
It was regarded as distinct by Nuttall and was named by him 
T. stenophyllum (Pl. Gambel. i. 151.) and perhaps that name 
may have to be restored to it, in which ease the T. stenophyl- 
lum of Boissier may be called T. lineare. 
T. AMPLECTENS, Torr. & Gray. Fl. i. 319. Usually 3—10 
inches high, the branches very slender, but firm (even rigid 
when dry), numerous, decumbent: involucre of 6—9 linear- 
oblong, obtuse lobes nearly equalling the calyx: head few- 
flowered: corolla in age almost obpyramidal, 7. e. inflated 
gradually from a narrow base to a broad, truncate summit, 
somewhat reticulate-veined : pod short-stipitate, 2-seeded. 
Abundant on rather dry plains and hillsides : flowers white,
