Phyllanthus comprises approximately 1,270 species, making it one of the world's largest plant genera. Molecular data so far are of limited value for understanding Phylianthus because of the sheer size of the genus. They can, however, help sort-out cryptic species and provide information on the origin of suspected introduced species. One of the seemingly most widespread species is P. reticulatus, which has been recorded from Asia, Australia, Africa, and Jamaica. The name is based on a mixed collection from tropical Asia now in the Lamarck herbarium, and we lectotypify it here. We use nuclear ITS sequences to test the broad treatment of P. reticulatus in recent floras, identify records of "P. reticuiattis" from Africa, and investigate the origin of P. reticulatus on Jamaica. A maximum likelihood tree for accessions of P. reticutatus from throughout its supposed range (plus relevant outgroups) shows that the Jamaican plants represent the Asian species, that the African plants called P. reticulatus belong to a separate clade for which P. polyspermus is the oldest available name, and that the sensu lato treatment of P. reticulatus in recent floras is unjustified. Treating the Asian entities P. reticulatus and P. microcarpus as separate species appears justified, and identical ITS sequences in Asian and Jamaican P. reticuiattis indicate a recent introduction. The first "island botanists," J. Macfadyen and N. Wilson, introduced many plants from India in the 1800s, and theirs are the oldest Jamaican collections of P. reticuiatus. Since the species was introduced to Jamaica without its obligate Epicepiiaia moth pollinators, it does not set fruit, persisting instead by vegetative growth.

Gilbert & P. T. Li), scandent shrubs ( P. reticulatus Poir) and succulents ( P. mirabilis Müller Argoviensis) (Macbride , Webster , Chantaranothai , Li and Gilbert ). Extensive previous palynological studies of Phyllanthus s.s. have revealed that the pollen morphology of this genus is also very diverse (Punt , , Punt and Rentrop , Bor , Meewis and Punt , Lobreau‐Callen et al , Webster and Carpenter , , Wei et al , Sagun and Van der Ham , Santiago et al , Furness , Chen et al ), including oblate to prolate shapes; 3–11‐zonocolporate (colpori with one or two endoapertures), syncolpate, pantocolporate, pantoporate, zonoporate, or even inaperturate aperture patterns, and perforate, reticulate, vermiculate and pilate exine ornamentations. In addition, within taxa with reticulate exine, uni‐reticulate, bi‐reticulate exine, micro‐ reticulate and coarsely reticulate, and lumina with and without free sexine elements have all been reported within the genus.…”

“…The palynology of the subtribe Phyllanthinae is relatively well‐studied, and pollen morphology has provided valuable information for taxonomic studies (Webster , Wei et al , Sagun and van der Ham , Webster and Carpenter , , Chen et al ). The diversity of aperture types and exine ornamentation patterns observed in pollen grains of species in Phyllanthus s.s. have been used in species delimitation (Wei et al , Chen et al ). However, the genus Glochidion has rarely been referred to in palynology (Deng , Sagun and van der Ham , Webster and Carpenter ).…”

The pollen morphology of twenty‐five Chinese species belonging to two sections of Glochidion and one species from Phyllanthus subgen. Phyllanthodendron was examined using scanning electron microscopy (SEM). The results showed that pollen grains of Glochidion are isopolar, spheroidal to rarely subprolate in shape, (3)4–5(6)‐colporate in aperture pattern, and tectate‐reticulate to tectate‐rugulate in exine ornamentation. Fusion of colpus ends was observed in some pollen grains of G. pseudo‐obscurum and G. wrightii. The pollen grains of Phyllanthus dunnianus are similar to those of Glochidion species in their spheroidal shape and four‐colporate aperture pattern, but are slightly larger in size, and show tectate‐perforate exine ornamentation. In Glochidion, pollen morphology appears to be useful for distinguishing several macromorphologically similar. Additionally, palynological characters provide evidence for the taxonomy of the supergenus Phyllanthus s.l.

To prepare verticinone derivatives with significant antitussive, expectorant, and antiasthmatic activities, the compounds 3beta-acetylverticinone (1), 3-ketoverticinone (2), 3beta-benzoylverticinone (3), 3beta-propionylverticinone (4), 3beta-butyrylverticinone (5), and 3beta-butoxycarbonylverticinone (6) have been prepared. All of these are new compounds. Among them, 1-6 exhibited potent antitussive and expectorant activities; 1 and 3-6 displayed various antiasthmatic activities. The antitussive activity of 1-6, the expectorant activity of 1-2 and 4-6, and the antiasthmatic activity of 1 are higher than those of verticinone. The results demonstrated that 1 had dominant biological activities, suggesting that it would be a potential antitussive, expectorant, and antiasthmatic agent.
