LUNDELL: THE GENUS PARATHESIS 169 
65. PARATHESIS SUBULATA Lundell, Wrightia 3:74. 1963. Fig. 63 and Plate 30. 
Shrub, up to 3 m. high, branchlets slender, at first sparsely appressed tomentu- 
lose, glabrescent; leaves with slender petioles 5-15 mm. long; leaf blades lanceo- 
late-oblong. 5-9.5 em. long, 1.2-2.3 cm. wide, apex caudate-acuminate, base 
acuminate, glabrous, membranaceous, slightly paler beneath, obscurely and 
minutely crenulate. pellucid-punctate, costa slender and elevated beneath, 
plane above, primary lateral veins slender, 12-15 on each side; inflorescences 
axillary, few-flowered, paniculate, 3-6 cm. long, usually 1 -branched, glabrous or 
essentially so, the peduncles slender but firmly erect; bractlets foliaceous, up to 
7 mm. long; pedicels slender, 3-6 mm. long; flowers corymbose; sepals about 
0.75 mm. long, sparsely and minutely puberulent, orange-punctate; corolla and 
stamens unknown; ovary ovoid, minutely appressed tomentulose; style slender, 
3-4 mm. long, puberulent basally; placenta depressed-globose; ovules 7 or 8, 
uniseriate, exposed apically; young fruits globose.

(LL, US). 
GUATEMALA.—HUvEHUETENANGO: Sierra de los Cuchumatanes, vicinity of Maxbal, 
about 17 miles north of Barillas, alt. 1500 m., July 15-16, 1942, Julian A. Steyermark 48829 
(F, US), shrub, 10 ft. tall, ovary rose-colored; Sierra de los Cuchumatanes, Cerro Victoria near 
Barillas, in Liquidambar- Pinus forest, alt. 1800-2000 m., July 29, 1942, Julian A. Steyermark 
49714 (F, type; US, isotype), shrub, 8-10 ft. tall, fruit turning dull rose-red, leaves firmly 
membranous, deep green above, paler grass green beneath. 
Clearly akin to P. tenuis Standl. of Oaxaca, but differing notably in having 
7 or 8 ovules exposed apically, and with style up to 4 mm. long. In P. tenwis 
the 3 or 4 ovules are enclosed. The oblongish leaves with longer petioles and 
minute subulate sepals are other distinguishing characteristics. 
The Chiapas collection, C. A. Purpus 23, has 5 or 6 ovules, exposed apically 
as in P. subulata, and slender erect acuminate anthers up to 1.8 mm. long with 
two or three dorsal glands. In P. tenuzs the anthers are similar, but smaller and 
usually glandless. The Chiapas shrub is in some aspects intermediate between 
the two species, but referable to P. subulata.

Fig. 64 and Plate 31. 
Branchlets slender, minutely tomentulose with appressed hairs; leaves with 
slender petioles 10-14 mm. long; leaf blades obovate-elliptic or elliptic, 5.5—9 
em. long, 2.5-3.5 em. wide, apex obtusely short-acuminate, base cuneate, mem- 
branaceous, entire or undulate-crenate, sparsely pubescent on lower surface with 
small appressed stellate hairs, glabrescent, costa elevated beneath, the primary 
lateral veins slender, 12-14 on each side; inflorescences axillary, divaricately 
paniculate, 2-branched, the peduncles and branches very slender and lax, many- 
flowered, 10-13 cm. long, sparingly pubescent with minute appressed stellate 
hairs; pedicels filiform, 4-10 mm. long, apparently accrescent, glabrous; flowers 
corymbose, at anthesis about 4 mm. long, minutely papillose-puberulent; sepals 
subulate, 1-1.4 mm. long, orange-punctate; petals linear-lanceolate, 4—5 mm. 
long, papillose-tomentose within over entire surface, inconspicuously orange- 
punctate; stamens about 3.75 mm. long; filaments 2.7-3 mm. long, sparingly 
papillose-puberulent below middle; anthers erect, linear-triangular, about 1.2
