Description:

Species Description - Shrubs 1-3 m tall; young stems and leaves glabrous; bark of older stems pale yellowish-gray. Sympodial units unifoliate. Leaves broadly elliptic to orbicular, widest at or just below the middle, glabrous and shining adaxially, glabrous and drying somewhat golden abaxially, with 3-9 pairs of main lateral veins, the secondary venation conspicuously parallel; lamina 11 -21 cm long, 6-19 cm wide, the apex acute, the base acute to rounded; petioles 1-2 cm long. Inflorescences opposite the leaves or sometimes internodal, simple, 3-10-flowered, glabrous except for a few reddish papillose trichomes on the tips of the axes; pedicel scars closely packed, not overlapping. Buds ovoid with pointed tips, ca. ½ exserted from the calyx tube. Pedicels at anthesis deflexed, glabrous, 5-7 mm long, ca. 0.5 mm diam. at the base and apex. Flowers with the calyx tube conical, 1-1.5 mm long, the lobes deltate to long-triangular, 1-1.5 mm long, glabrous; corolla greenish-white to bright green (fide Ramos et al 1603), 0.7-1 cm diam., lobed ca. 3/4 of the way to the base, the lobes more or less planar at anthesis, the tips and margins of the lobes minutely papillose; anthers 2-2.5 mm long, ca. 1 mm wide, poridical at the tips, the pores teardrop shaped; free portion of the filaments 0.5-1 mm long, the filament tube 0.25-0.5 mm long, glabrous; ovary glabrous; style straight, 4-5 mm long, glabrous; stigma capitate, the surface minutely papillose. Fruit a globose, green to greenish-white berry, 1-1.5 cm diam.; fruiting pedicels woody, erect, 1-1.5 cm long, 1.5-2 mm diam. at the base. Seeds dark brown, ovoid-reniform, 4-4.5 mm long, 2-2.5 mm wide, the surfaces minutely pitted. Chromosome number not known.

Discussion:

Solanum cyclophyllum is closely related to S. triplinervium of Gorgona Island off the coast of Nariño department. It shares with that species three-nerved venation (at the base) and completely glabrous foliage. The regular, deltate to long-triangular calyx lobes and ovate to rounded leaves readily distinguish it from S. triplinervium. The parallel secondary venation shared between the two species is much more prominent in S. triplinervium (see Fig. 125).

The only other member of the Solanum unifoliatum species group occurring at middle to high elevations is S. longevirgatum, which is easily distinguished from S. cyclophyllum by its golden pubescent stems and young leaves and its erose leaf margins.
