ROSE—MEXICAN AND CENTRAL AMERICAN PLANTS. 17 
This species is certainly congeneric with the other species referred to Mantroda, 
having the same habit and inflorescence, and differing only in its peculiarly curved 
perianth tube and its short stamens. 
In its curved tube it approaches Polianthes, but it has single flowers and exserted 
stamens. Agare saponaria (M. brachystachys) is figured and described as having a 
curved tube, although this is not so strongly bent asin the above species. In its 
short stamens it is unlike all the Manfredas except MV. maculosa, which has stamens 
shorter than the lobes of the perianth. 
This species may be considered a good generic type by some, 
2. Manfreda maculosa (Hook.) Rose. 
Agare maculosa, Hook. Bot. Mag. 85: pl. 5122, 1859, 
Agave maculata, Engelm. Bot. Mex. Bound. 214. 1859, not Regel, 1856. 
Basal leaves 6 to 10, blotched with brown or sometimes with green, the margins 
serrulate; scape 3 to 6 dm. long, with about 6 small bracts, purplish; flowers [0° to 
25, nearly sessile, almost 5 cm. long (including ovary); tube narrowly funnel- 
shaped, a little longer than the purplish or greenish white, somewhat spreading 
lobes; filaments a little shorter than the perianth lobes; anther cells exserted, 
brownish; stigmas 3-lobed. 
This species has repeatedly flowered in the National Botanic Garden, Specimens 
prepared by J. N. Rose are in the National Herbarium: (nos, 4055, 4076). 
Baker in his Handbook of Amaryllideae takes up .1. maculosa Regel for this plant; 
but according to Regel’s description his species has long-exserted stamens, and it is 
more than likely to be one of the several spotted-leaved species of central Mexico. 
The type of Regel’s plant was grown from seed sent by Karwinski from Menico. 
Karwinski collected largely if not entirely in south Mexico, especially in the State 
of Oaxaca. In 1840 to 1843 he collected for the Russian Government, at which 
time he probably obtained the seed of this plant. 
Dr. Engelmann was of the opinion that this plant was not the maculata of Regel, 
and in his revision of the Agaves he employed Hooker’s specific name, imaet/osd. 
Miss Mulford, however, in her revision of the North American Agaves hesitatingly 
adopts Regel’s name, but points out clearly that it possesses characters which show 
it to be specifically distinct. 
As Miss Mulford states, the species is rather variable and T am not inclined to 
recognize as a variety Agave maculosa brerituba Engelm. (A. imceulata brevituba 
Mulford). 
This species is contined entirely to Texas. 
The following paragraph was drawn up from a Texas specimen which flowered in 
Washington several years ago: 
A form haying the leaves spotted with green was sent in along with the purple 
spotted leaved form; corolla tube shorter than the lobes and the lobes very spread- 
ing; filaments apparently longer than in other forms, but scarcely longer than the 
segments; segments at first greenish yellow but in age becoming a dark pink; stamens 
rounded, not emarginate. This appears to be the .f. maculosa brevituba of Engelmann. 
Here also seems to belong A. maculosa as figured by Hooker in Curtis’s Botanical 
Magazine, vol. 85, pl. 6122, for it has the same spotted leaves, the short perianth 
tubes tinged with yellow, and the round stigmas. 
For a number of years I had growing in one of the greenhouses roots of the so-call¢ d 
Agave maculata from Texas. In the summer of 1898 IT transplanted this pot to my 
yard and in June it flowered, having sent up two flowering stalks. These had 
peduncles 6 dm. long, more or less purplish and glaucous, bearing 9 and 10 leaves or 
leaf-like bracts, and each had about 25 flowers. The flowers when they first opened 
had nearly white filaments, style, and segments, the latter being somewhat purplish 
without, but in age all became dark reddish rose, the segments becoming strongly 
reflexed.
