The anthers have apical hairs, as in P. serrulata (Sw.) Mez, but P. guate- 
malensis is not to be confused with that species of Hispaniola. From related 
species, P. guatemalensis differs in such significant characteristics as having 
fewer ovules, finer denser stellate pubescence on undersurface of young leaves, 
anthers with acutely triangular black-punctate area dorsally, and ridged ovary 
hirtellous-tomentose on the ridges. 
28. PARATHESIS OXYPHYLLA Lundell, Wrightia 2: 68. 1963. Fig. 28 and Plate 16. 
Branchlets rather stout, minutely pubescent at first with fine sessile stellate 
hairs, essentially stellate-lepidote; leaves subsessile or with marginate petioles 
up to 1.5 em. long; leaf blades oblanceolate or lanceolate, 8-14 cm. long, 3-5.5 
cm. wide, apex acuminate, base acute and decurrent on petiole, conspicuously 
crenulate-serrulate, sparsely papillose at base above along midvein, the petiole 
and blade finely stellate pubescent beneath with appressed hairs, bizonal, 
glabrescent, the marginal zone glabrescent first, chartaceous, the costa and 
primary veins elevated beneath, the veins slightly impressed above; inflores- 
cences terminal, up to 17 cm. long, narrowly pyramidal, tripinnately paniculate, 
the branches rather remote, short and stout, minutely stellate-lepidote; flowers 
subcorymbose, up to 5.5 mm. long at anthesis, minutely tomentose at first, 
papillose-puberulent; pedicels 3-5 mm. long; sepals narrowly lanceolate, 1.5~2 
mm. long, acuminate, black-punctate; petals narrowly lanceolate, united at 
base, about 5.5 mm. long, black-punctate in lines, papillose-tomentose within 
apically and along edges; stamens 3-3.5 mm. long; filaments up to 1.5 mm. long; 
anthers erect, lanceolate, up to 2.5 mm. long, apiculate, dorsifixed one-third 
above base, with black-punctate triangular area above attachment, with glands 
extending down into lobes; ovary ovoid, minutely and finely tomentose to 
middle; style up to 4.5 mm. long; placenta acicular apically; ovules 6 or 7, erect, 
uniseriate, enclosed.

eality, C. Juergensen 203 (K, type; G, isotype). 
The species is notable for the remote short rather stout branches of the 
inflorescences and finely tomentose ovary.
