ROSE——-MEXICAN AND CENTRAL AMERICAN PLANTS. 317 
Heliocarpus popayanensis trichopodus (Turez. ) Baker, Journ. Bot. 836: 132. 1898, 
Heliocarpus trichopodus Turez. Bull. Soc. Nat. Mose. 81!: 225, 1858. 
Heliocarpus laevis Rose, sp. nov. 
Small tree; old branches reddish, glabrous; young branches densely stellate; 
leaves lanceolate, mostly rounded at base, acuminate, thin, with scattered stellate 
hairs above, softly and densely stellate beneath, 3 or 5-neryed at base; inflorescence 
a small open panicle; sepals 4 or 5, each with a small appendage near the tip; fruit 
sessile, orbicular. 
Collected by J. N. Rose west of Bolaios River near Bolafios, September 17, 1897 
(no. 2860), 
This species is near MZ. polyandrus, bat with much smaller appendages to the 
sepals, leaves not cordate at base, and leaves not glabrate. 
Heliocarpus polyandrus 8. Wats. Proc. Am. Acad. 21: 420. 1886. 
This species has recently been collected in fruit from near the type locality by Mr. 
#. A. Goldman (no. 226). The fruit is orbicular and sessile and it therefore belongs 
to my second section and near HH. palmeri. 
Heliocarpus velutinus Rose sp. noy. 
Undoubtedly a tree, but size not known, branches light brown, densely stellate- 
pubescent especially when young; leaves (only upper ones seen) nearly as broad as 
long, 18 em. long on petioles 6 em. long, above green and somewhat stellate, beneath 
very pale, densely and finely stellate-pubescent and reticulated, slightly 3-lobed, the 
lobes shortly acuminate; inflorescence a large terminal panicle; pedicels 2 to 4 mm. 
long; sepals minute, densely stellate-pubescent, 24 mm. long, not appendaged at tip; 
petals and stamens not seén; fruit sessile, small, oblong, the body 5 mm. long by 2 
mm. broad, stellate-pubescent on the faces, the margin of plumose hairs narrower 
than the breadth of carpel. 
A very distinct species easily recognized by the white velvety under surface of the 
leaves and small oblong fruits. When keyed out in the synopsis above referred to 
it comes nearest [7/. glanduliferus, but is of course abundantly distinct from that species. 
Collected by Mr. C. G, Pringle near Yautepec, Morelos, in 1902 (no. 8694). 
TWO NEW BASSWOODS. 
Mr. Hemsley in the Biologia Centrali-Americana credits two species 
of Tilia to Mexico, but unfortunately gives them both the same 
name, viz, Ze mertcana. We seems to have seen no specimens of his 
second species, the 7. mexicana Schlecht. Under his first species the 
“7. mexicana Benth,” he records all the Kew material, which must 
embrace more than one form anda part of which doubtless belongs 
with the true 7) mericuna. Below I present the description of the 
two new species: 
Tilia occidentalis Rose, sp. noy. 
Tree; bark on old branches dark brown and glabrous; young branches densely 
lanate; leaves broadly ovate to nearly orbicular, LO.cm. or less long, green and -glab- 
rous above, densely and rather coarsely tomentose beneath when young but becom- 
ing glabrate in age and then only slightly paler than the upper surface, the margin 
sharply toothed, strongly oblique at base or often slightly cordate, acute; the winged 
peduncle stalked at base, the wings unequal below, 8 to 12 em. long; pedicels, calyx, 
and ovary densely pubescent. 
Collected by C. G. Pringle in mountains about Patzcuaro, Michoacan, July 22, 
1892 (no, 4126, type) and by E. W. Nelson at base of Mount Tancitaro, Michoacan, 
1903 (no. 6874). 
Perhaps nearest 7. mexicana, but certainly with very different leaves.
