The study presents the morphology, anatomy and mathematical modelling in Benguet lily (), a threatened species from the Cordillera Central Range and was often misidentified with the weedy . The plant is an annual herb with linear, spiral leaves; pure white, perfect, funnel-shaped, showy flowers; septicidal elongated capsule; and, brown, light, winged seeds. New findings in the study include the description of the capsule and seeds, biometric measurements of the different plant organs, the significant correlation and regression model of plant height and stem diameter for certain floral measurement, and its diagnostic characteristics vis-à-vis . Interesting findings on the taxon's anatomy show a cross between a typical monocot and a typical dicot anatomy. It has a bifacial leaf structure (a common dicot character) but its spongy layer is not as widely spaced like in dicot leaf. The stem has a distinct cortex and pith (a dicot character) but has a scattered vascular bundles (a monocot character). Lastly, some roots have a narrow pith at the centre of the stele (a monocot character) while some roots have metaxylem elements at the centermost structure (a dicot character). Further studies need to be conducted to determine the ecological significance of these features.
该研究展示了本格特百合（）的形态学、解剖学和数学模型，本格特百合是来自中科迪勒拉山脉的一种濒危物种，常被误认作杂草。该植物为一年生草本，具线形、螺旋状叶片；纯白色、完全花、漏斗状、艳丽花朵；室间开裂的细长蒴果；以及棕色、轻质、具翅种子。该研究的新发现包括对蒴果和种子的描述、不同植物器官的生物特征测量、特定花部测量中株高与茎直径的显著相关性和回归模型，以及与……相比的诊断特征。关于该分类群解剖学的有趣发现表明，它具有典型单子叶植物和典型双子叶植物解剖结构的交叉特征。它具有双面叶结构（常见的双子叶植物特征），但其海绵层不像双子叶植物叶片那样间隔广泛。茎有明显的皮层和髓（双子叶植物特征），但维管束呈散生状（单子叶植物特征）。最后，一些根在中柱中央有狭窄的髓（单子叶植物特征），而一些根在最中央结构有后生木质部成分（双子叶植物特征）。需要进一步开展研究以确定这些特征的生态意义。
