It grows in partially shaded sites along forest edges or in cleared, disturbed areas between 200–900 m elevation. Plants were in both flower and fruit in January, and late flower into full fruit from June to September; they are likely to flower and fruit throughout the year. The epithet abajoense is in reference to the main location where it has been collected (Río Abajo Forest Reserve), a wonderful nature preserve where all of the Piper species in Puerto Rico are known to co-occur.</p><p>Piper abajoense belongs to clade Radula (see Fig. 1), which is a monophyletic group of species distinguished by the presence of pinnately veined leaves, typically erect inflorescences with the flowers, fruits, and bracts forming distinct bands around the spikes, bracts often fimbriate-margined and lacking an umbo, lack of basal callosities at the junction of the lamina and petiole, and fruits triangular or rounded. In Puerto Rico this species most closely resembles Piper hispidum Sw., but can be distinguished by the ± glabrous fruits (vs. apically densely puberulent), stylose (vs. estylose) ovary and young fruits, laterally (vs. apically) dehiscent anthers, and shorter inflorescences (&lt;8 cm vs. 10 + cm).</p><p>The following key can be used to identify P. abajoense and the other 10 species of Piper known from Puerto Rico.</p></div>	https://treatment.plazi.org/id/03E8878FEE2FFFCAFF4CEDF7FA2781A8	Public Domain	No known copyright restrictions apply.

Clase 4267 and 4268 (JBSD, SEMO).</p><p>Notes— Piper claseanum is apparently endemic to the southcentral mountain range known as Sierra Martín García in the province of Azua in the Dominican Republic. It grows in shaded sites on steep, rocky hillsides from 700–850 m elevation. Plants were in late flower or mature fruit in January, so it is likely to be in full flower in November and December, with fruits persisting into February or March; additional collecting at these times would be necessary for confirmation, and similar efforts in other months would be helpful to determine if year-round flowering and fruiting occurs. The epithet claseanum is in honor of Teodoro Clase, long-time student of the flora of the Dominican Republic and one of the initial individuals to recognize this new species.</p><p>Piper claseanum belongs to clade Enckea, which includes a group of species with palmately veined leaves and the usual presence of two basal callosities at the petiole/lamina junction, erect inflorescences with the flowers, fruits, and associated bracts usually loosely organized around the inflorescence and not forming distinct bands, bracts sessile or short-pedicellate, cucullate in overall shape, and the fruits globose, ovoid, or flask-shaped. This species is most closely related to Piper samanense Urban based on molecular data (Fig. 1), and in vegetative condition appears similar due to the relatively small, leathery leaves with three primary veins and the numerous pellucid dots evident upon drying. They also share the unusual white fruit color, which appears to be a synapomorphy for these taxa. The two species can be easily distinguished because P. samanense has more densely packed flowers along the densely white-pubescent (vs. puberulent) rachis, the pedicels are shorter and broader, and only develop if the fruit matures (= pseudo-pedicellate), the fruits are more densely puberulent to pubescent, and the stigma lobes are quite narrow.</p><p>It is also interesting to note that the endemic species of Enckea from the Greater Antilles form a clade that is sister to the largely continental taxa (only the widespread Piper amalago L. and P. reticulatum L. occur in the Antilles). Further sampling of the enckeoid species endemic to Cuba [e.g. Piper lindenianum C. DC., P. mananthum C. Wright, P. perditum Trel., and P. sphaerocarpum (Griseb.) C. DC. ex C. Wright] and Haiti ( P. sinuatispicum Trel. and P. perpallidum Ekman, Urb. &amp; Trel.) would be necessary to confirm if this pattern holds.</p><p>The following key can be used to identify P. claseanum and other palmate-veined species from the Dominican Republic.</p></div>	https://treatment.plazi.org/id/03E8878FEE28FFC8FF55EDD0FA7D82AD	Public Domain	No known copyright restrictions apply.
