ROSE—MEXICAN AND CENTRAL AMERICAN PLANTS. 19 
The plant here characterized departs in some particulars from Baker’s description 
of A. pubescens, especially in the length and color of the perianth lobes, and may 
yet prove to be different. This is, however, the only species which is known to have 
pubescent leaves. 
Mr. J. M. Greenman, in a letter dated November 29, 1898, says: 
“T believe you are right in considering Poliauthes maculata and .tgare pubescens to 
be one and the same. [ have just compared the illustrations and read over the 
descriptions, and they seem to me to be the same.” 
5. Manfreda pringlei Rose, sp. nov. 
Stems slender, 9 to 10 dm, high, glabrous; leaves linear-lanceolate, about 3 dm. 
long, 15 to 20 mim. broad, green with brown spots; flowers in a short compact raceme 
or spike, perhaps becoming more open in age; ovary 10 mm. long; perianth tube 8 to 
12 mm. long; lobes purplish, 8 mm. long; stamens inserted near the middle of the 
tube, long-exserted, 5 em. long; fruit orbicular, 15 mm. in diameter. 
Collected by Mr. C. G. Pringle on San Felipe in 1884 (no. 4745), and distributed 
as Ayare guttata, from which it differs. 
Perhaps nearest M. brachystachys, but with smaller flowers and with different inser- 
tion of the stamens. 
6. Manfreda brunnea ( Wats.) Rose. 
Agave brunnea Wats. Proc. Am. Acad. 26: 156. 1891. 
Leaves few, thickish, 1 dm. long, 12 to 20 mm. broad near the middle; flowering 
stem 6 dim. long, about 6-flowered; flowers sessile; ovary 12 min. long; perianth 3 
to 3.5 em. long, the lobes about haif as long as the narrow tube; stamens and style 
long-exserted. 
Collected by Mr ©. G. Pringle on the battlefield of Buena Vista, Tamaulipas, 
Mexico, July, 1888 (no. 2218). 
7. Manfreda virginica (L.) Salish. Gen. Pl. Frag. 78. 1866. 
Agare virginica L. Sp. Pl. 1: 325. 1758. 
Leaves all from the base, about 10, at first erect, then spreading, nearly flat, about 
2 dm. long, 3 em. wide at about two-thirds of the distance from the base, then 
gradually tapering downward to the narrow base and upward more abruptly into a 
slender acumination with a weak point, green, but somewhat mealy, not at all 
spotted; margins slightly serrulate; scape 7 to 8 dm. long, about 7-bracteate, glaucous; 
spike about 6 dm. long, about 30-flowered; flowers solitary and distant, the lower 
on pedicels 6 to 8 mm. long, the upper short-pediceled; ovary 14 mm, long, some- 
what constricted above; perianth greenish, less than 2.5 cm. long; segements 8 mm. 
long, erect, margins involute, hairy at tip; stamens shortly exserted; filaments dark 
purple, inserted near the base of the tube; anthers whitish, spotted with brown, 
style shorter than the stamens; capsule globose, 14 to 20 mim. in diameter. 
The writer has collected this species on the Kentucky River, near Lexington, and 
flowered it in the National Botanic Garden. 
Distribution: Maryland to southern Indiana and Missouri and to eastern Texas and 
Florida. 
‘T have not been able from the description to separate Ayare aliberti Baker (Allibertia 
intermedia Marion) from the above. Indeed, it was originally distributed as Agave 
virginica by Haage & Schmidt. 
Manfreda virginica tigrina (Engelm.) Rose. 
Agave virginiana tigrina Engelm. Trans. St. Louis Acad. 3: 302. 1875. 
A spotted-leaved form first found in Bluffton, South Carolina, and recently reported 
by Dr. Trelease from Missouri. I have seen the type specimen in the Missouri 
Botanical Garden.
