within, sparingly setose and with short appressed pubescence without, reddish or 

 bluish above, greenish below, somewhat gibbous at base, the upper sepal slightly 

 larger than the 5 lower; the appendages alternating with the sepals, only half their 

 length, and bearing long 8eta^ as long as the sepals; petals 2, dorsal, narrowly 

 oblong, apiculate, red, G nun. long, each subtended by a small Hat s<]uamula below 

 the sinus; stamens 11, equally inserted and all glabrous; two dorsal much shorter; 

 the other 9 much exserted, the 5 opposite the sepals longer than the 4 alternating 

 with them; style and ovary glabrous; ovules 9; gland reflexed. 



Collected by J. N. Rose in the foothills between Acaponeta and Pedro Paulo, 

 Jalisco, August 2, 18S17 (No. 1917), and between Pedro Paulo and San Blascito, 

 Tepic, August 4 (No. 3341). 



This species is nearest C. <jraeiliJlova but quite different. 



The specific name is suggested by the crest of hairs which crowns the llower buds. 



Explanation of Plate.— Fig. 1 , a flowering branch ; fig. 2, flower with the calyx split open and the 

 petals detached ; Jig. 3, stylo and gland. Fig. 1, natural size ; figs. 2 and 3, scale of 3. 



Cuphea koehneana Rose, sp. now Plate XXIV. 



Annual; stems simple, (5 to 7 dm. high, clothed with short, rather stiff pubescence; 

 leaves opposite, broadly lanceolate, 10 to 15 cm. long, including the slender petiole 

 (18 to 35 mm. long), somewhat oblique and tapering at base, acuminate, very thin, 

 with scattered appressed pubescence on both sides, paler beneath, the lateral veins 

 prominent beneath; the inflorescence terminal and paniculate; bracts long, fili- 

 form, setose; calyx slender, 18 to 20 mm. long, shortly spurred at base, somewhat 

 enlarged at the top, two-nerved within, glabrous below; two dorsal petals 12 to 15 

 mm. long, 8 mm. broad, tapering into a slender claw 2 to 5 mm. long, deep purple, 

 inserted on each side of the dorsal sepal just above the corresponding sinus; 2 ven- 

 tral petals much smaller (5 nun. long); stamens 11, some of them exserted, two a 

 little farther than the others, these densely clothed with long, purple wool; seeds 

 about 9; disk dorsal, reilexed. 



Collected by Mr. C. G. Pringle at Cuernavaca, Mexico (No. 6657). 



This species belongs in Koehue's section Diploptychia, but is very distinct from 

 the other species of the section. Perhaps nearest to C. nudicostata and C.pinetorttm. 



Explanation op Plate.— Fig. 1, a dowering branch; fig. 2, a flower, showing the calyx split open 

 and the petals detached; fig. 3, the style and gland; figs, i and 5, face and side views of seed. Fig. 

 1, natural size; all dissections scale of 3. 

 Gronovia longifiora Kose, sp. nov. Figure 30. 



Leaves slightly lobed, with open sinus ; Uowers tubular, 20 mm. long, ovary 2 mm. 

 long, tube 10 mm. long, sepals 2 to 3 mm. long; petals and stamens longer than the 

 sepals, free to the base, the former 14 to 16 mm. long; fruit strongly 5- winged, the 

 wings tool bed. 



Collected by C. G. Pringle on lava beds near Cuernavaca, November 3, 1896 (No.

Hippociatea pauciflora Kose, sp. nov. 



Rather low woody vines; leaves opposite, obovate to spatulate-oblong, 5 to 7.5 cm.

 nate; petioles 4 mm. long; stipules small, lacerated; flowers not seen ; fruit solitary, 

 or in small diehotomous clusters of twos to fours; peduncles 2.5 to 3.8 cm. long, 

 either axillary or terminal; carpels oblong, 5 to 6.5 cm. long. 



Collected by J. N. Rose, near Rosario, State of Sinaloa, June 10, 1897 (No. 1587). 

 Only a single plant of this species was seen, in a deep wooded canyon about 1 mile 

 north of Rosario near the river. 

 Hippocratea utilis Rose, sp. nov. 



High-climbing woody vines ; leaves opposite, oblong, 7.5 to 8.5 cm. long, 3.5 to 5 

 cm. broad, obtuse, rounded at base, glabrous, dark green above, paler beneath,
