What are the morphological characteristics of this plant?
Ophioglossum thermale has a solitary, erect, lanceolate fertile spike that emerges from a basal rosette of fleshy, simple, linear-to-oblong leaves. The vegetative portion consists of a single, undivided leaf blade that lacks the complex dissection found in many other ophioglossoid ferns. Its reproductive structure is a dense, cylindrical spike composed of numerous small, closely packed sporangia. This spike typically develops a distinct reddish or brownish hue as the spores mature. The overall plant architecture is relatively small and adapted to the specific geothermal soil conditions of its habitat.
What is the geographical distribution of this plant?
This plant is endemic to the geothermal areas of the northern part of the island of Taiwan. It is specifically found growing in the warm, moist substrates near thermal springs and hot springs within this limited region. Its distribution is highly restricted due to its strict dependence on the unique microclimates created by volcanic activity. Because it requires consistent high temperatures and humidity, it cannot survive in the surrounding non-thermal landscapes. Consequently, this species occupies a very small and fragmented ecological niche.
How is this plant cultivated?
This plant requires a specialized cultivation environment characterized by constant high humidity, consistent warmth, and a substrate composed of acidic peat moss mixed with perlite or sand.
Because it is a rare species often found in geothermal areas, maintaining a stable temperature around 25 to 30 degrees Celsius is vital for its survival. You must provide bright, filtered light to prevent leaf scorch while ensuring the growing medium remains perpetually moist but not waterlogged. Regular misting or the use of a terrarium helps replicate its natural tropical habitat.
Monitoring the water quality is also essential, as using distilled or rainwater prevents mineral buildup that can harm the delicate root system.
What parts of this plant are used medicinally?
This plant Ophioglossum thermale is used medicinally through its entire herb, which includes the leaves, stems, and roots. Local populations often prepare decoctions or infusions from the whole plant to treat various ailments. The chemical compounds found within the vegetative structure are believed to possess specific therapeutic properties. Practitioners typically collect the herb during certain growth stages to ensure maximum potency. This traditional use highlights the importance of the complete botanical structure in folk medicine.
According to a study published by "Fitoterapia", two new peroxy fatty acids named thermalic acids A (1) and B (2) were isolated from the herba of Ophioglossum thermale Kom. These two acids were identified alongside eight known compounds, specifically (3β)-methyl-3-hydroxy-urs-11-en-28 oate (3), luteolin (4), quercetin (5), 3-methoxyquercetin (6), ophioglonol (7), ophioglonol 4'-O-α-D-glucopyranoside (8), pedunculosumoside B (9), and syringol (10). The structures of 1 and 2 were determined using HRESIMS, EIMS, 1D and 2D NMR, and electronic circular dichroiism (ECD) spectra. Both of these two acids exhibited potential antibacterial activities against Staphylococcus aureus, Bacillus subtilis, and Escherichia coli. This research represents the first report of peroxy fatty acids isolated from herbaceous plants of the Ophioglossaceae family.
