1922] TRELEASE—PEPEROMIA 139 
With scapes scarcely surpassing the leaves, bearing 4-6 sub- 
apical spikes scarcely 3 cm. long, it is var. pinulana C.DC., MS. 
n. var. (P. pinulana C.DC., Bot. Jahrb. 10:289. 1889). 
Guatemala, the type from Pinula, near Xalapa (Lehmann 1693). 
PEPEROMIA SCIAPHILA C.DC., An. Inst. Fis.-Geogr. Costa 
Rica 9:175. (1898 ?).— ?Peperomia ovato-peltata Auct., as to Costa 
Rica.—Acaulescent; leaves broadly ovate, blunt-acuminate, 
rounded at base, peltate below the middle; spikes scarcely 2 cm. 
long, 2-7 nearly sessile at end of a filiform scape surpassing the 
leaves; ovary ovoid, subacute; stigma apical.—Fig. 14. 
Costa Rica, the type from the Rio Virilla near San Juan (Tonduz 
9630). 
PEPEROMIA OVATO-PELTATA C.DC., Jour. Botany 4:132. 
1866.—Aspect of the preceding; leaves broadly ovate, acuminate, 
peltate one-third above the rounded or subcordate base; spikes 
solitary or 2 or 3 near the end of a filiform scape equaling or 
surpassing the leaves; ovary round-ovoid, contracted into an 
equilong fleshy style; stigma apical. 
A problematic species, perhaps representing a depauperate form of the 
preceding and if so to replace it in name. ‘Two specimens (New Spain, Pavon; 
Costa Rica, Hoffmann 521) are mentioned with the original description, but 
both are questioned there.
