VOL. 5] New Species of Lower California Plants. 163 
pearance and reflexed involucres, The plant of the Cape Region 
referred to P. gracile grows also along the southern coast and is 
very different. It is not exactly the plant from Magdalena Bay, 
the type locality, for it is taller, 2-4 feet, more shrubby and the 
lower leaves are flatter. The Magdalena Bay plant is about a 
foot high, the leaves are short and terete and the stems are fas- 
tigiate. 
Dysodia littoralis. Annual, spreading from the base, glab- 
rous, stems 6-15 cm. long; leaves alternate, fleshy, generally en- 
tire, spatulate, 2-5 cm. long, 4-6 mm. wide, in luxuriant forms 
some leaves have short, broad lobes; glands between the margin 
and midrib, except when lobes are present, and then they are 
marginal; peduncles terminal, monocephalous; heads hemispheri- 
cal, disk 2 cm. in diameter; scales of the involucre obtuse, scari- 
ous-margined; scales of the pappus about 20, dissected at apex 
into 5-10 sete. 
This species is related to D. anthemidifolia, a plant growing at 
Magdalena Bay and northward. It is the southern representative 
of that showy Dysodia, and is even more handsome. Its habitat 
is along the coast, on sand drifts, from 15 miles south of Pesca- 
dero to Cabo San Lucas. From D. anthemidifolia it differs in 
having broad, entire leaves, instead of narrow, pectinately di- 
vided ones, a spreading instead of an erect habit, larger flowers 
and akenes and longer pappus. 
Gochnatia arborescens. Arborescent, sometimes becoming a 
tree 3-4 m. high and 2-3 dm. in diameter, young growth sparing- 
ly tomentose; leaves chartaceous, nearly smooth, ovate, acumi- 
nate or obtuse, cuneate at base, larger ones 5 cm. long, 3-4 cm, 
wide, on petioles 5 mm. long; infloresence crowded at the ends of 
the branches; heads 2 cm. long, 15-20 flowered; involucre light 
green, cylindrical; scales in 8-10 series, decreasing gradually in 
size, the lower ones minute, the larger ones ovate-lanceolate, 
erose, sparingly ciliate; corolla 12 mm. long, lobes ™% as long, re- 
curved, with thickened tips when in bloom; style tips flattened, 
nearly truncate; pappus bristles numerous, almost equalling the 
corolla, with some shorter ones intermixed; akenes villous, 5 
mm. long.
