Yucca necopina was originally described based only on plants from a single locality in Somervell County. Shinners’ sketchy description compared it with Y. arkansana, and he suggested that it might be a hybrid between Y. pallida and Y. arkansana. More recently, G. M. Diggs et al. (1999) reported new locations of Y. necopina from Hood, Parker, and Tarrant counties, and noted that molecular evidence provided to them by K. H. Clary supports its separate recognition.

Yucca necopina ( englanti )

tarjonnut wikipedia EN

Yucca necopina Shinners,[2] the Brazos River yucca or Glen Rose yucca,[3][4] is a species in the family Asparagaceae. It is a rare endemic native to a small region in north-central Texas.[5]

Description

This plant is a perennial shrub that grows in small colonies of rosettes.[4] The plant grows to a height of 2 feet, with bloom stalks reaching a height of 7 feet.[4] Its flowers are greenish-white and bloom in Spring.[4] The species is similar to Y. pallida and Y. arkansana,[5] and at one time it was thought the species could be a hybrid of the two; later DNA evidence supports it being distinct.[6]

Distribution and habitat

This species grows in river terraces and deep sand, and is native to Somervell, Hood, Parker, and Tarrant Counties in Texas, west of Dallas and Fort Worth.[6][5]
