RHIPSALIS MINUTIFLORA K. SCH. Martius, Flora Bras. 4 (2): 271. 1890

• Plant stem and branches thin, graceful, tubular, with longitudinal striations when dry, branches dichotomous, glabrous,
• Scales leaflike, very small, triangular-ovate, sunken, very soon dropping off, axils of the scales ‘something’ and a single spine, very small, subulate curved ‘something’.
• Flowers single, well spaced on the branches, supported by a persistent spine.
• Ovary oblong, twice as long as wide, borne laterally and above the sunken glabrous solitary scale, ?multilocular.
• Tepals external ones very small, wide triangular, blunt, very thick, middle ones oval, innermost ?oblong, obtuse, membranaceous.
• Stamens few, shorter than the largest tepals by one quarter, filaments slender with very small anthers divided into two lobes, style without stigmas almost equaling the stamens, divided into 4 short, papillose, converging stigmas.

Rhipsalis funalis Miq. ß. gracilior in Pl. Kappler. n.1720; , Salm-Dyck

Branches tubular, 10-20cm long, 1mm or barely 1.5mm diam. ‘something’, bright green or paler.

• Scales 0.5mm long, reddish.
• Spines ‘something’, at the most 2mm long, similar to the scales but with a liitle wool in the axils ‘something’.
• Ovary 2.5-3mm long, 1-1.5mm diam., base ‘something’ tapering to the tip, with a scale barely 0.5mm long.
• Tepals 0.3 – 0.5 – 1.5 – 2mm long, inner ones barely 1mm
• Stamens filament 2mm long, anthers barely 0.3mm diam.
• Style 2mm long, stigmas barely 0.5mm long, in floral examination glued into a ‘something’ mass

Habitat in Surinam : Hostmann n. 393, Wullschlagel; in district ‘something’ Surinam: Kappler n. 1720.

Observation; Rhipsalis cassutha Gaertn. is recalled to mind with this species, ‘something’ branches slender, flowers twice as and more shorter, and especially the ‘something’ ovary is easily seen
