Conservation
Peperomia dindygulensis is com­mon and widespread in Asian countries. The popula­tions grow in protected and non protected areas. The specimens were collected from throughout Thailand. We propose the category of Least Concern (LC) (IUCN2011).
Distribution
China, India, Sri Lanka, Myanmar, Thailand, Vietnam, Laos, Cambodia and Malay­sia.
Ecology
Growing on mountain summits, rock-falls, in shallow depressions, exposed rock slopes and in open areas on rock platforms.
Morphology General Habit
Perennial herbs 20 - 25 cm high, erect, epilithic; forming a clump, many main stems with 3 - 4 branchlets; stolons present, without rooting at basal nodes; internodes 2 - 4 cm long with red or reddish spots or bands, fleshy, velutinous, rarely scabrous or puberulous
Morphology Leaves
Leaves opposite decussate or 4-verticillate on terminal branches and caducous; petiole 0.5 - 1cm long, velutinous, scabrous or pilose; lamina chartaceous when dry, obovate or elliptic, asymmetri­cal, 3 - 5x1.5 - 3 cm, base cuneate or acute, apex acute, margin undulate and pilose, indument densest on young leaves and upper denser than lower surfaces; venation palmately 3-veined, pilose
Morphology Reproductive morphology Flowers
Flower with an orbicular floral bract, 0.5 - 0.8 mm diam., covering basal part of ovary
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens; filaments 0.2 - 0.3 mm long; anthers with 2 valves, 0.3 - 0.5 mm long, exserted at anthesis
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary ovoid, immersed within rachial pit; stigmas capitate, pubescent
Morphology Reproductive morphology Fruits
Fruit with short pseudopedicel, ±globose, 0.8 - 1 mm diam., dark brown or black, with sticky glandular hairs on each papilla and persistent style tip
Morphology Reproductive morphology Inflorescences
Inflorescence single or a fascicle with 2 - 4 spikes per shoot, terminal or in the axils of the upper leaves, 8 - 15 x 0.05 - 0.1 cm, erect, cylindrical, green; rachis glabrous, with sparse flowers; peduncle 1 - 1.5 cm long, puberulous or slightly scabrous
Note
Gilbert & Nian (1999) treated Peperomia dindygulensis under P. blanda (Jacq.) Kunth and selected the collection of Wight in Wallich 6663B at K-W as the lectotype and P as the isolectotype. Later, we found that additional isolectotypes were deposited in K and BM. The type locality of P. dindygulensis is Dindygul, India and P. blanda is Jamaica. We examined the type specimens of both species, voucher specimens, line and colour draw­ings from Turpin (1816- 1829), publications from Jacquin (1789) and Lanjouw (1957), specimens in Thai herbaria, living specimens in European botanic gardens and living specimens collected throughout Thailand. We found that they share similar gross morphological characters but differ in detail in so many other characters that they should not be synonymised. We therefore recognise and reinstate P. dindygulensis. The species have very different geographical distributions with P. dindygulensis dis­tributed in Asia and P. blanda the Americas/West Indies, Africa and Yemen. The phyllotaxy of P. dindygulensis is opposite decussate or 4- verticillate on terminal shoot (vs opposite on basal and whorled on terminal shoot). The stems, leaves, petioles and peduncles are velutinous, rarely scabrous or pilose (vs stems and petioles densely villosus and densely pubescent on both surfaces of leaf). The floral bract is orbicular (vs ovate with short stalk). The fruits are globose with caducous sticky glandular trichomes each on papilla (vs ellipsoid with only papillae). The fruits have pseudopedicels (vs sessile and immersed in rachial pit). The sticky glandular trichome and pseudopedicel are easily caducous which cannot be observed on dry specimens, but is easily observed on living specimens. The specific epithet refers to Dindygul (the city in the South Indian state of Tamil Nadu) from which the type specimens were collected.
Phenology
Flowering and fruiting occur between December and July.
