Detailed description

Plants polycarpic, height in flower 30–130 mm. Caudex unbranched, c.80 mm long. Root unbranched, 1.5–6.0 mm diameter at stem base. Flowering stems lateral only, 1–5 per plant, 1.1–2.0 mm diam. at base, stems tinted purple-black; lateral flowering stems erect or decumbent; flowering stem leaves 1–4 pairs per stem, lowest pedicels from near apex of flowering stem. Rosette of leaves distinct from flowering stem leaves; leaves narrowly elliptic or elliptic, 10–52 × 3.5–12.0 mm, tinted crimson below or tinted purple-black and speckled purple, channelled (petiole channelled also), not recurved, petiole indistinct to distinct, 9.5–12.5 × 1.0–4.1 mm wide; apex acute or rounded. Flowering stems 1-3 stems per plant. Flowering leaves as for rosette leaves but the upper ones sessile. Pedicels one per leaf axil, 3–37 mm long, 1.2–1.5 mm diameter. Flowers 1–5(-8)per plant, 15–23 mm long. Calyx 7.5–14.2 mm long, green tinted purple-black, hairs at calyx–corolla fusion line absent or present; lobes 4.5–9.5 × 3.1–4.7 mm at base, plane, apices acute, margins smooth or minutely denticulate, sinus hairs sparse. Corolla 11.8–22.5 mm long, white; tube 3.5–6.0 mm long; lobes 9.7–16 mm long, 5.8–10.6 mm wide, hairs below sinus absent or present; nectary 0.8–1.2–1.8 mm from corolla base. Filaments 7.5–13 mm long from corolla base, 0.9–2.0(–2.6) mm wide. Anthers 1.7–3.0 mm long, anther wall blue-black, mouth yellow, extrorse at anthesis; pollen yellow. Stigma colourless. Ovules 28–56 per ovary. Capsule 20–27 mm long.

Similar taxa

Close to Gentianella bellidiflora from which it differs in being shorter, 30–130 mm tall (70–280 mm tall in Otago G. bellidifolia); having purple-spotted leaves with a dark purple petiole (green and unspotted in G. bellidifolia), and fewer flowers, 1–8 per plant (Otago G. bellidifolia has 4–26 flowers per plant); fewer flowering stems, 1–3 per plant (Otago G. bellidifolia has 1–4 stems per plant). The calyx lobes are wider, 3.1–4.7 mm wide (cf. 1.7–4.4) mm in G. bellidifolia), and the filaments are wider on average 1.7 mm rather than 1.2 mm.

Distribution

Endemic. New Zealand. South Island (Otago, Southland).

Habitat

Subalpine - Alpine cushion bogs and low-angled flushes.

Current conservation status

The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2022-2023 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes replaces all previous NZTCS lists for vascular plants. Previous assessments can be found here.

Wetland plant indicator status rating

Information derived from the revised national wetland plant list prepared to assist councils in delineating and monitoring wetlands (Clarkson et al., 2021 Manaaki Whenua – Landcare Research Contract Report LC3975 for Hawke’s Bay Regional Council). The national plant list categorises plants by the extent to which they are found in wetlands and not ‘drylands’. The indicator status ratings are OBL (obligate wetland), FACW (facultative wetland), FAC (facultative), FACU (facultative upland), and UPL (obligate upland). If you have suggestions for the Wetland Indicator Status Rating, please contact: [Enable JavaScript to view protected content]

OBL: Obligate Wetland

Almost always is a hydrophyte, rarely in uplands (non-wetlands).

Etymology

gentianella: Little Gentiana (named after Gentius, 6th century king of Illyria, who found the roots of the yellow gentian to have a healing effect on his malaria-stricken troops)

amabilis: From the Latin amare, ‘to love’, amabilis can be translated as ‘worthy of love’ or ‘pleasing’, botany was also called scienta amabilis ‘the pleasing science’

NVS code

The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.

Regional conservation statuses

The regional threat classification system leverages off the national assessments in the NZTCS, providing information relevant for the regional context. Otago conservation status information is sourced from the “Regional conservation status of indigenous vascular plants in Otago” Jarvie S et al. (2024) report.
