|discussion=<p>Species ca. 30 (14 in the flora).</p><!--
--><p>In areas of west Texas, New Mexico, and Arizona, the species of Nolina are not always well defined. There is variation in the presence or absence of marginal teeth on the leaves and placement of the inflorescences within or beyond the leaves. Collectors should take good notes about the plant habit and morphology and include these with their collections. Further study is needed on Nolina throughout its range. Some species of Nolina are extremely infrequent. Some are on federal and/or state rare and endangered species lists, and possibly some of those listed with a state should be listed federally.</p><!--
--><p>J. C. Dice (1988) studied section Arborescens of Nolina in the United States, and presented extensive descriptions and discussion of N. bigelovii, N. parryi, N. cismontana, and N. interrata.</p>
