LUNDELL: THE GENUS PARATHESIS 97 
epunctate filaments, subcoriaceous glabrous leaves, and the glabrous ovary. 
The number of ovules is unusual for such a small-flowered species. 
31. PARATHESIS MEXICANA Lundell, Wrightia 2: 66. 1963. Fig. 31. 
Tree, twigs finely tomentose with pale brown stellate hairs; leaves thin, the 
petioles finely tomentose, up to 1.5 em. long; leaf blades oblanceolate or oblanceo- 
late-elliptic, 9-15 em. long, 3-5.7 em. wide, apex subabruptly acuminate, base 
acuminate and decurrent, subentire, pubescent on undersurface with fine silky 
stellate sessile hairs, subappressed or rather loose, the marginal zone glabrescent, 
the costa and lateral veins elevated beneath, rather obscure and plane above; 
inflorescences terminal, shorter than the leaves, the panicles rather congested, 
6-10 cm. long, 5-9 em. wide at base, finely tomentose with reddish-brown 
stellate hairs; flowers finely tomentose, in congested corymbs or subracemose, 
the buds slender, ovoid, 5-6 mm. long; pedicels short, 2.5-4 mm. long; calyx 
punctate, the sepals ovate, 1.2~1.5 mm. long, acuminate; petals slender, linear- 
punctate, up to 6 mm. long, papillose-tomentose within along margins and above 
middle, united at base; stamens 3 mm. long; anthers erect, orange-punctate 
above point of attachment, lanceolate-oblong, 2 mm. long, apiculate, dorsifixed ; 
filaments punctate, about 1.5 mm. long; ovary hirsute at apex; style hairy at 
base; placenta cylindrical, subtruncate and minutely apiculate; ovules 5 or 6, 
enclosed, basally erect, uniseriate; fruits depressed-globose, drying about 6 
mm. in diam.

Although the filaments are conspicuously punctate, the punctate area of the 
anthers is rather inconspicuous, orange-colored, and immediately above the 
point of attachment. Although this is the most distinctive characteristic, P. 
mexicana is distinguished further by its rather small compact inflorescences, 
short pedicels not over 4 mm. long, fine reddish-brown tomentum of the in- 
florescences, rather loose fine sessile stellate hairs on undersurface of leaves, and 
by the cylindrical subtruncate placenta with 5 or 6 ovules. 
32. Paratuesis AGosTINIANA Lundell, Wrightia 3: 108. 1964. Fig. 32. 
Branchlets rather stout, brown tomentose apically with minute closely ap- 
pressed stellate hairs; leaves with narrowly marginate petioles 1-2 cm. long; 
leaf blades lanceolate, lanceolate-oblong, or oblanceolate, 12.5-18 cm. long, 
4-6 cm. wide, apex subabruptly acuminate, base cuneate and decurrent on 
petiole, membranaceous, crenulate, at first pubescent on lower surface with 
fine stellate ferruginous closely appressed hairs, bizonal, the marginal zone 
glabrescent early, glabrous above, pellucid-punctate, costa plane above, elevated 
beneath, primary veins slender; inflorescences terminal, narrowly paniculate, 
12-18 em. long, about 6.5 cm. wide at base, ferruginous-tomentulose with 
fine small stellate appressed hairs; pedicels slender, short, 2.5-3.5 mm. long, 
minutely puberulent; flowers corymbose, ferruginous-puberulent, pellucid- 
punctate, 4-5 mm. long at anthesis; sepals 5, ovate-triangular, about 1 mm. 
long, acute, pellucid-punctate; petals lanceolate, 4.5-5 mm. long, pellucid-
