Validation of Calochortus ownbeyi (Liliaceae), a new species from northwestern Mexico
Phytotaxa, 2017 The name Calochortus ownbeyi has been extensively used even though it was not validly published. Accordingly, we are here validating and illustrating this species. Calochortus ownbeyi can be confused with C. venustulus, but there is morphological and molecular evidence that they are distinct species.

, 2022 168 pages ; A key goal of evolutionary biology is to understand the processes that drive and maintain biodiversity across heterogeneous landscapes. My dissertation leverages a highly polymorphic system in Calochortus, C. venustus, to identify and to interpret the evolutionary significance of geographical patterns of floral trait variation, genetic ...

HEAVY METAL ACCUMULATION AND THE NATURE OF EDAPHIC ENDEMISM IN THE GENUS CALOCHORTUS (LILIACEAE)
American Journal of Botany, 1985Bulb and leaf tissues from five species in the genus Calochortus and the soils from collection sites were analyzed for cation and trace element concentrations. All five species, only three of which are considered ultramafic endemics, possessed high concentrations of nickel and copper in both ...

Related species of similar morphology can differ greatly in distribution and abundance. Elucidating reasons for such differences can contribute to an understanding of intrinsic limiting factors and the causes of rarity. We studied sympatric populations of two terrestrial lilies with contrasting distributions: Calochortus lyallii, which is ...

(1) Edaphically-restricted rare species differ in some aspects from closely related, widespread congeners, but not in others. Characteristics that do not differ between three rare mariposa lilies (Calochortus obispoensis Lemm., C. tiburonensis Hill, and C. pulchellus Dougl. ex Benth.) and one common species (C. albus Dougl.

Calochortus occidentalis (Liliaceae), a new species from western Mexico
Phytotaxa, 2018Calochortus fuscus Schultes (1829: 131) was described based on material collected by Wilhelm Friedrich von Karwinski in Mexico, who participated in two excursions in Mexico (1827–1832, 1841–1843). His collections were purchased by European institutions, especially by Botanische Staatssamlung München (M) in Munich, Germany.

Seed Morphology and Taxonomic Relationships in Calochortus (Liliaceae)
Systematic Botany, 1989Seeds of 37 species of Calochortus were examined using scanning electron microscopy. Two major seed forms were observed. "Calochortoid" seeds are irregular in shape with roughly tetragonal to irregular testa cells lacking secondary thickenings in the outer cell walls.
