Mamiuuaria (CorypHantTua) vivireara, Haworth, Engelm. in Watson’s 
Bot. King’s Expl. 117—A common plant on the Western plains from the 
Missouri to Texas, extending in the mountain regions as far west as Arizona 
and South Utah, the large, deep rose-colored or purple flowers, with fringed 
sepals and lance-linear, acuminate petals, green, oval berries, with light 
brown, pitted seeds, readily distinguish the species. The form of the plains 
is lower and often densely cespitose-spreading; the mountain plant is often 
simple and larger. The largest form, which comes from Arizona, I had at 
one time distinguished as M. Arizonica, but must now consider it as only a 
gigantic vivipara, 3-5’ high, 4’ in diameter, with spines often over 1’ long 
on rather broad and spreading tubercles. Rothrock, 1874, (203), is a smaller 
form, from Camp Apache, Ariz. 
MamILuaRIA (CoRYPHANTHA) CHLORANTHA, 0. sp.—Similar to the last, 
but with broader yellow petals; stems oval to cylindrical, 3’ wide, some- 
times 8-9’ high; tubercles compressed from above; 20-25 outer spines gray, 
almost in 2 series; 6-8 or 9 inner ones stouter, $-1’ long, reddish or 
brownish only at the tip; flowers yellowish or greenish-yellow, crowded on 
the top of the plant, 14’ long and wide, often 1—2 small, fringed sepals on 
the ovary (which also occasionally is seen in vivipara); sepals lanceolate, 
fringed; petals lanceolate or linear-lanceolate, acute, denticulate; 7-9 
whitish stigmas, erect-spreading—Southern Utah, east of Saint George, Dr. 
Parry. I. E. Johnson. 
Ecutnocactus Wisiizent, Engelm—Very large, often over 3° high 
and half as much in diameter; at first globose, then ovate to cylindrical, 
and many-seeded. Seeds ovate or oblong. Stems annual, roots perennial, often procumbent and rooting. 
Leaves cordate at base asa lobed. Tendrils 2-many-cleft. Flowers large, yellow. Fruit often very 
arge.—BENTHAM & Hoo ey
