Der Blütenstand wird 2 bis 3 m hoch mit zahlreichen langen variablen, Verzweigungen. Die weißen bis tanfarbenen Blüten sind 3 mm lang und im Durchmesser. Die Blühperiode reicht von Mai bis Juni.

Die in der Reife holzigen Kapselfrüchte sind 8 bis 10 mm lang und im Durchmesser. Die hellbraunen, kugelförmigen bis länglichen Samen sind 2 bis 3 mm im Durchmesser.

Nolina nelsonii ist bis minus 12 °C frosthart. Sie ist kaum bekannt.

Verbreitung und Systematik

Nolina nelsonii ist in Mexiko im Bundesstaat Tamaulipas verbreitet. Sie ist mit Dasylirion-Arten vergesellschaftet.

Nolina nelsonii ist Mitglied der Sektion Arborescentes. Sie ist selten, geographisch isoliert und weist Ähnlichkeiten mit Nolina parryi auf, jedoch werden Unterschiede in Blütenstand und Struktur der Blätter deutlich.

Nolina nelsonii

provided by wikipedia EN

Nolina nelsonii (Blue Nolina or Nelson's Bear Grass), often misspelled Nolina nelsoni, is a flowering plant in the genus Nolina. The species was first described in 1906;[1] in its genus, it is morphologically most similar to Nolina parryi. This extremely drought-tolerant plant is native to the deserts and montane regions in the State of Tamaulipas in northern/northeastern Mexico. It is known to be cold-hardy to at least −12 °C. It develops a trunk measuring from one to several meters high, making it an arborescent member of its genus. The bluish-green leaves, with finely toothed margins, are borne in dense rosettes, each with up to several hundred stiff linear (narrow) leaves up to 70 centimeters long. It is dioecious; upon reaching sexual maturity, its white-flowered inflorescence appears in Spring. The fruit capsules are around 80 mm in length, containing light-brown, spherical to oblong seeds 2–3 mm in diameter. After blooming, the plant's main trunk dies and multiple lateral trunks emerge to take its place.
