Resembling A. hypolewcum, but with very different pubescence on the stems, the 
leaves less tomentose beneath, not so rough above, more abruptly acuminate, the 
basal lobes more overlapping, the teeth and calyx lobes different, ete.

TWO NEW KOSTELETZKYAS AND A NEW NAME. 
Kosteletzkya malvaviscana Rose, sp. nov. Puate LXVII. 
Stem 120 to 180 cm. high; branches herbaceous, greenish, somewhat stellate-pubes- 
cent; leaves ovate, 7 to 12 em. long, with a broad rounded or somewhat cordate base, 
acute or acuminate, stellate on both surfaces, somewhat irregularly crenate; petioles 
2 to 5 cm. long; inflorescence a few-flowered axillary raceme on slender, sometimes 
elongated, peduncles; pedicels slender, 5 to 12 mm. long; involucre bracts 6 or 7, 
linear, about two-thirds the length of the calyx, 7 mm. long, parted to the middle, 
stellate-pubescent; lobes ovate, acute, 3-nerved; petals purplish or rose-colored, 2 
em. long, erect and Malvyastrum-like; stamen tube elongated, much longer than the 
flowers; capsule depressed, 5-angled; cells 1-seeded as in genus; seed glabrous. 
Collected by C.V. Hartman at Las Cuevas, Sonora, October 15, 1890, and distributed 
as A’. cordata from which it.must be very distinet.

Kosteletzkya tampicensis ( Moric.) Rose. 
Hibiscus tampicensis Moric. Mem. Soc. Phys. Gen. 7: 260. pl. 14. 1833. 
This plant must be a Kosteletzkya rather than a Hibiscus, having the peculiar fruit 
of the former. 
The species is based on Berlandier’s no, 210, coming from near Tampico, Mexico. 
Kosteletzkya violacea Rose, sp. nov. Pirate LXVIILI. 
Herbaceous, perhaps a meter high, more or less branched, densely pilose; leaves 
ovate to nearly orbicular, sometimes 3-lobed, finely stellate-pubescent on both sides 
and sometimes with large stellate or single hairs intermixed, serrate; flowers axillary 
and solitary; peduncles slender, 2 to 3.cm. long; bracts 6 to 8, linear, hardly half as 
long as the calyx; calyx deeply 5-parted; corolla spreading, pinkish or violet, 3 em. 
broad; stamens united into a slender tube; anthers sessile, arranged in 3 rings; 
styles 5; capsule sharply 5-angled, finely stellate-pubescent, bristly on the angles. 
Collected by C. G. Pringle at Jojutla, Morelos, June 13, 1901 (no. 9671) and 1902 
(no. 8663, type).

pubescent above, softly stellate pubescent beneath, 6 to 10 em. long, with a deep 
rather narrow sinus; flowers very abundant in axillary panicles; peduncles slender, 
pilose as well as stellate, 8 to 16 mm. long, jointed near the apex; corolla violet,
