7.5 to 10 em. long; spikes 5 or 6 in the axils of the leaves; involucre at the base of 
the peduncle, 4-lobed and striate; flowers numerous; stamens yellow, indefinite, 
distinct or slightly cohering at base; pod not seen. 
Collected by Mr. C. G. Pringle in the Tomillin Canyon, altitude 3,000 feet (No. 
6113). Iam also inclined to refer here Mr. Nelson’s No. 2056, although the specimens 
are so young it is difficult to be certain. Mr. Nelson’s plant was collected along the 
road between Tlaliscatilla, Guerrero, and Tlapancingo, Oaxaca, December 6, 1894. 
This species, which is well marked by its large leaflets and long flowering spikes, 
appears to belong to Bentham’s series Gummiferi, subseries Basibracteatic, and 
near the species spadicigera and amentacea. It differs from both of these very greatly 
in its foliage. Its leaflets are much like those of 4. reniformis, but the stipules are 
very different and the spikes longer. 
Bucnida grandiflora (Groenland) Rose; Microsperma grandiflora Groenland, Rev. 
Hortic. 1861, 349, t. 84 (1861). 
Herb, 6 to 12 dm. high, pubescent with barbed hairs; leaves alternate, orbicular, 
cordate at base, obtuse, 3- to 5-nerved, with rounded obtuse lobes, crenate, pubescent 
on both sides, 6 to 15 em. in diameter; petioles about the length of the diameter of 
blade; flowers solitary, 5 to 10 cm. long; calyx cup-shaped, 18 mm. high, clothed 
with echinate hairs; lobes long (4 em.), tapering from the base to an acute tip, 
simply pilose; petals white, oblong, 6 cm. long, acute and villose without; stamens 
very numerous, much longer than the petals, 10 cm. long; filaments marked with a 
spiral thread; styles 13 cm. long. 
This is a very distinct species and by far the largest-flowered one of the genus. 
Nearest EF. bartonioides, but with flowers twice as large, different pubescence and 
different toothing of the leaves. 
Collected by Mr. E. W. Nelson 6 miles above Dominguilla, State of Oaxaca, altitude 
5,000 to 6,000 feet, October 3, 1894 (No. 1589); also by Mr. C. G. Pringle (No. 4645). 
We have not seen specimens of Microsperma grandiflora, but from the description 
and figure there seems to be no doubt of our reference. 
The species was originally collected by a Mexican traveler, Mr. Roezl, from whom 
it was received about 1860 by Vilmorin, Andrieux & Co., who introduced it into 
Europe. It was described and figured in the Revue Horticole by Groenland and 
spoken of from the florist’s point of view in the most glowing terms. The following 
is a translation in part of his remarks: 
“Aside from the remarkable beauty of this new species, we have full assurance 
that from the close of the month of May up to the present time it has been constantly 
in flower; even at this moment (beginning of September) it still bears flower buds 
in as large numbers as in the month of June, so that presumably it does not rest 
before winter. Ought not this quality alone to recommend it warmly to the atten- 
tion of our readers? 
“A glance at figure 84, which represents Microsperma grandiflora at one-fourth its 
natural size, suffices moreover to show that it is of a quite uncommon beauty. The 
numerous stamens which are consolidated at the base, and which far exceed the 
ample corolla, are of a perfect elegance; the color of the petals is not yellow, as in 
the species hitherto known, but pure white with a light-greenish tint on the outer 
face; the flowers, which during blossoming are erect, afterwards turn in such a way 
that the fruits are pendent; the alternate, long-petioled leaves, which in their 
form much resemble those of Microsperma bartonioides, are, however, more indented 
and more undulate on the margin; they are, like the stem, covered with a thick 
down of short hair.”
