P. Woodsoni Lundell, Ann. Mo. Bot. Gard. 28: 458. 1941. 
A small tree up to 15 m. tall, branchlets slender to rather stout, apically 
ferruginous-lepidote with minute very closely appressed stellate hairs, these 
searcely discernible; leaves with slender petioles usually 1-1.5 em. long, some- 
times up to 2.5 em. long; leaf blades lanceolate, oblong-elliptic or oblanceolate, 
5-20 cm. long, 1.5-5 em. wide, acuminate at apex and base, chartaceous or 
membranaceous, obscurely crenulate to entire, at first minutely and sparsely 
lepidote beneath with appressed stellate hairs, conspicuously black-punctate, 
striolate, costa elevated beneath, the primary lateral veins very slender; in- 
florescences axillary, paniculate, up to 15 cm. long, long pedunculate, the 
peduncles and branches slender, 1- or 2-branched, sparsely and minutely puberu- 
lent; pedicels slender, 6.5-11 mm. long, minutely puberulent; flowers subcorym- 
bose, minutely papillose-puberulent, up to 6 mm. long at anthesis; sepals tri- 
angular, up to 1.2 mm. long, red-black punctate; petals narrowly lanceolate, up 
to 6 mm. long, papillose-tomentose over entire inner surface, densely red-black 
punctate in lines; stamens 3-3.5 mm. long; filaments slender, glabrous, 1.5—-2 
mm. long, not punctate; anthers erect, dorsifixed one-third above base, lanceo- 
late, 1.75-2.4 mm. long, attenuate apically and apiculate, epunctate or with 
one to several minute black glands dorsally; ovary puberulent or tomentulose to 
middle and at base of style or only apically; style slender, about 5 mm. long, 
punctate in lines; placenta depressed-globose, apiculate; ovules 7-9, uniseriate, 
enclosed; fruits purple, depressed-globose, drying about 7 mm. in diam. 
PANAMA.—Cnrrraut: Valley of upper R. Chiriqui Viejo, alt. 1300-1900 m., July 27, 1937, 
Peggy & Gene White 27 (MICH, type; A, LL, MO, NY, isotypes), tree, 5-6 m., fls. pink with 
sweet odor; Rio Chiriqui Viejo valley, between El Volcan and Cerro Punta, Mar. 19, 1938, 
Gene White 19 (F, MO), tree 10 ft., petals pink, fragrant; Volcan de Chiriqui, vicinity of Casita 
Alta, ca. 1500-2000 m., June 28-July 2, 1938, R. E. Woodson, Jr., Paul H. Allen & R. J. 
Seibert 798 (A, K, MICH), tree 4 m., fls. pale pink, fruit purple-black, depressed spherically, 
1.2 cm.; upper valley of Rio Chiriqui Viejo, trail from Paso Ancho to Monte Lirio, alt. 1500— 
2000 m., Jan. 16, 1939, Paul H. Allen 1598 (GH, LL, MO, US), tree 10 m.; Finca Lerida to 
Pefia Blanca, alt. 1750-2000 m., July 9, 1940, R. E. Woodson, Jr. & R. W. Schery 331 (MICH, 
type of P. Woodsoni; GH, K, isotypes), tree, corolla pink, berries deep purple, patelliform; 
Cerro Punta, alt. 2000 m., May 24, 1946, Paul H. Allen 3485 (F, G, MO, NY, 8, UC, US), 
tree, 15 m., fls. pink. 
Additional collections and field studies are needed to determine the status of 
P. Woodsoni, and for the present I am considering it a synonym. It differs in 
having pedicels up to 11 mm. long compared to 6.5 mm. in the type of P. Secberti1, 
its ovary is puberulent to below the middle, rather than tomentulose apically, 
and the anthers are mostly concolorous and caudate apically. 
P. Seibertii appears to have affinity to P. Moritziana Mez.
