Iron Crown

On this field day, the Pondoland CREW group convened at our usual meeting point on Beacon Hill. We were pleased to welcome Lulu and Maike, who joined us for the day’s survey. Lulu generously brought homemade lemon cordial, prepared from lemons from her tree in Gauteng—a thoughtful gesture warmly received by the group.

Our team proceeded in convoy, travelling cautiously through Western Heights, where cattle are unfortunately still present within the reserve. We made our way to the far end of the track, stopping at The Iron Crown, specifically to record Erica cerinthoides, which had been in flower for several weeks. Although past peak, we were fortunate to observe the final flush of its brilliant coral-red blooms, standing out vividly against the senescing grasses. This species, known for its fire-adapted ecology, remains visually striking even at the tail end of its flowering phase.

On the rocky outcrops near the cliff edge, we located Centella glabrata, nestled in crevices where moisture lingers slightly longer. Further into the grassland, the team encountered numerous individuals of Eulophia parviflora, flowering prolifically. The population included both long-spurred and short-spurred forms, and we made comparative notes on individuals bearing leaves versus those flowering while still leafless—a known trait within this genus where flowering often precedes foliage emergence.

The survey pace was measured, allowing for detailed observations. Among the rocky patches, Burchellia bubalina was recorded in its uncommon red-flowered form. This species is typically orange-flowered, and we reflected on a rare yellow-flowered form previously observed in the region. The specimen observed was robust, demonstrating the species' well-known hardiness.

In the dappled shade beneath isolated trees, we recorded several moisture-stressed individuals, including Haemanthus albiflos, Crassula sarmentosa var. integrifolia, and Crassula perfoliata var. heterotricha. All showed signs of drought stress, indicative of the current dry conditions and the urgent need for seasonal rainfall.

As the group returned to the vehicles, a final highlight emerged. Ushi observed a flowering Moraea, and closer inspection confirmed it as Moraea elliotii, identified by its characteristic long basal leaf. True to its species behaviour, the flower had opened in the early afternoon—M. elliotii is known for its precise phenology, with blooms reliably appearing at approximately 14:00, and each lasting only for the duration of a single day.

Moraea elliotii is a geophytic species belonging to the family Iridaceae. It survives extended dry periods by storing energy in an underground corm and emerges to flower only when environmental conditions—typically after rain—are favourable. The species is notable for its phenological precision: the delicate, powder-blue flowers open consistently in the early afternoon, around 2 o’clock, and each bloom lasts for just a single day.

The plant bears narrow, grass-like leaves that blend effectively into the surrounding vegetation, offering natural camouflage from herbivores. This morphological adaptation, combined with its underground storage organ, allows it to tolerate both grazing and seasonal fires. Moraea elliotii is frequently observed in recently burned grasslands, where post-fire nutrient availability and reduced competition provide ideal conditions for flowering and regeneration.

Eulophia parviflora – The name says it all: “parvi” means small, and “flora” refers to its flowers. These delicate blooms come in pale shades of green, yellow, or sometimes with purple tones. The species often flowers in response to fire or the first rains.

There are two notable spur variations. Some plants bear a long, narrow spur that extends behind the flower—likely an adaptation for long-tongued insect pollinators. Others have a much shorter spur, which could reflect natural variation, environmental adaptation, or reduced reliance on specific pollinators. Interestingly, some populations or individuals produce sterile flowers, which may not set seed but still play a role in attracting pollinators to fertile plants nearby.

Like many Eulophia species, this orchid often flowers before the leaves emerge. You may spot the flowering spikes rising straight from bare ground, seemingly leafless. Only later do narrow or linear leaves emerge from the underground tuber. In some cases, the plant remains leafless at flowering time, or shows only rudimentary leaf growth.
