“…The species is endemic to the Himalaya showing restricted distribution from Pakistan to Bhutan, with altitude range from 2,700-3,800 m (Muhammad 2011). T. govanianum grows during early spring and prefers cold, shaded, and moist habitats (Chauhan et al 2017).…”

“…Recently, T. govanianum has emerged as one of the most prized medicinal plants having high therapeutic value (Chauhan et al 2017). The rhizomes of this species are used in traditional medicine to facilitate the labor of childbirth, dysentery, healing of wounds, inflammation, antiseptic, boils, menstrual and sexual disorders (Chizzola et al 2008, Bhoyar et al 2011.…”

Detailed knowledge about the meiotic behavior of threatened plant species is crucial to develop successful conservation strategies. Here we provide a detailed account of the male meiotic behavior of Trillium govanianum Wall ex. D. Don an endangered endemic medicinal plant species of the Himalaya. We collected the plant material from the Bangus valley of the Kashmir Himalaya. The species showed chromosome number n=2x= 10, which is the first gametophytic report for this species. The pollen fertility was found to be in the range of 88-90%. The reduced fertility was due to the meiotic abnormalities such as chromatin stickiness, a late disjunction of bivalents, chromatin bridges, formation of laggards, and polysporads with micronuclei. The seed set was found to be 65.85%. The reduced seed set might be attributed to the presence of various meiotic abnormalities observed.

“…For example, its rhizomes and leaves are used for many treatments in neighboring countries in India and Pakistan, for inflammation, skin boils, backache, dysentery, healing of wounds, menstrual and sexual disorders, indigestion, kidney problems, livestock parasites, etc. (Chauhan 1999, Mahmood et al 2012, Rani et al 2013, Sharma and Samant 2014, Rahman et al 2015, Chauhan et al 2018).…”

“…Local harvesters usually collect whole populations by uprooting them. In addition, habitat degradation due to overgrazing and forest fire is another threat to the population of T. govanianum (Bhatt et al 2005, Thompson and Sharpe 2005, Chauhan et al 2018). Similarly, opening of canopy in old‐growth forest by clearing and cutting of canopy trees can degrade T. govanianum habitat and reduce its population.…”

Trillium govanianum is known to be used for primary health care and household economy, however detailed information on its ecology and importance for local economy has remained unknown. In this study, we investigated T. govanianum population, production and distribution range, as well as its use, trade and vulnerability in Nepal. We show that the current practice of T. govanianum rhizome marketing has resulted in unsustainable harvesting, putting in extreme pressure on its habitats and populations. Harvesting methods such as premature harvesting and mass collections, without knowing actual population size and distribution, may have serious negative effects on reproduction, growth and survival of the species. To gather data and information, we sampled 80 quadrats and 320 (1 × 1 m) nested plots along with 96 interviews. Information on species occurrence points was gathered from various sources including direct field sampling and predicted potential suitable habitat using a maximum entropy model (MaxEnt). Rapid vulnerability assessment (RVA) was used to assess the conservation status of the species. Our results showed that T. govanianum occurs in 26 districts of Nepal and can be expected in 10 more mountainous districts along the elevation range between 2400 m and 4050 m. Among the environmental factors, elevation, precipitation and temperature were found to be the most influential for the species' distribution. Market‐led unsustainable collections were prevalent and T. govanianum collections were traded as an adulterant to Paris polyphylla, a highly traded medicinal plant. We found that T. govanianum is a vulnerable species with threat category I. Therefore, conservation efforts are urgently needed, including protection of its key sites and habitats along with sustainable use so as to save its existence.

Trillium govanianum, a medicinal herb, exhibiting diverse morphometric traits and phytochemicals across developmental stages of plants. The changes in the chemical profile and steroidal saponin levels in the rhizome of T. govanianum across different developmental stages were previously unknown. This study categorizes rhizomes into three types based on scar presence: juvenile (5–10 scars, Type I), young (11–19 scars, Type II), and mature (21–29 scars, Type III). Rhizomes show varying sizes (length 1.2–4.7 cm, girth 0.3–1.6 cm), weight (0.18–5.0 g), and extractive yields (9.7–16.1 % w w‐1), with notable differences in saponin content (5.95–21.9 mg g–1). Ultra–high performance liquid chromatography–MS/MS (UHPLC–QTOF–MS/MS)‐based chemical profiling identifies 31 phytochemicals, mainly including diverse saponins. Ultra–high performance liquid chromatography coupled with evaporative light scattering detection (UHPLC–ELSD)‐based quantitative analysis of seven key saponins reveals stage–specific accumulation patterns, with protodioscin (P) and dioscin (DS) predominant in mature rhizomes. Statistical analysis confirms significant variation (p=0.001) in saponin levels across developmental stages with chemical constituent protodioscin (P=4.03±0.03–15.76±0.14 mg g‐1, PAve=9.79±3.03 mg g‐1) and dioscin (DS=1.23±0.06–3.93±0.07 mg g‐1, DSAve=2.59±0.70 mg g‐1) with acceptable power (p=0.738; |δ|>0.5) statistics for effective sample size (n=27 samples used in the study) of T. govanianum. Principal Component Analysis (PCA) and Euclidean clustering further highlighted chemotype distinctions.
