| Description: |
Rhizome short, ellipsoid to spindle-shaped, no persistent leaf bases; roots descending, sometimes becoming horizontal. Leaves up to 2 leaves but mostly 1, held at c.75° from the horizontal. Petiole up to 3.5 cm long, subterranean for about half of its length. Sterile lamina 14-39 × 2.5-5 mm, very narrowly elliptic in outline, apex pointed, base gradually diminishing in breadth, fertile lamina often concave above; fertile segment 3-6 cm long, inserted at or just above the base of the lamina. Sporangia 6-19 pairs. |
| Notes: | O. gracillimum, O. lusoafricanum and O. sandiae are, like O. caroticaule, narrow leaved Ophioglossum species. The leaf width:length ratio of O. caroticaule (1:7.2) differs from O. gracillimum (1:10-20) and O. sandiae (1:4.5). O. lusoafricanum has a leaf width: length ratio of 1:7-9 and a slender, linear rhizome. |
| Derivation of specific name: | caroticaule: rhizome resembling a carrot |
| Habitat: | Seasonally wet areas over sheetrock among scrub and short grasses along streams, shallow soils beneath seasonally dry deciduous woodland, sometimes in high altitude grassland. |
| Altitude range: (metres) | 700 - 1500 m |
