Description: Nolina longifoliaSN|33540]]SN|33535]] is a woody, slow-growing pachycaul plant which becomes arborescent with time and develops a curious, massive base to its 4 to 5 m tall stems.
Stems: Erect, 10-20 cm in diameter, with 1-6 branches.
Leaves 150 to 200 per rosette, persistent. Sheets (lamina), 1 (-1.5) m long, (8-) 10-15 (-20) mm wide, lanceolate, base 5-6 cm long and 4-5 cm wide, ovate, apex acute, long attenuated, arched with age, margin finely thoothed, green-yellowish, smooth.
Inflorescences: Paniculate, erect, 1.5-2 (-3) m long, peduncle 1.5-2.5 cm thick at base, primary branches, 20-30 cm long, numerous, with few buds (up to 5 buds per shoot, but usually developing 2 and fructifying only one) Fertile portion, 1-1.5 m long, bracts in the middle part of the
inflorescence greater than 30 cm long (up to 50 cm), apical ones up to 15 cm long, leaf-like, narrow. Pedicels, 7-12 mm long, articulated in the first third mear the base, sometimes very close to it.
Flowers: Unisexual. Tepals free, 2.5-3 (-4) mm long, 1.5-2 (-2.5) mm wide, elliptical to ovate. Inner ones slightly smaller, whitish, sometimes with green or brown spots and hyaline margin. Fertile stamens 6, free, shorter than tepals, up to 3 mm long, filaments ca. 2 mm long, anthers ca. 1.5 mm long.Ovary 3-lobed, lobes rounded at apex, ca. 2 mm long. Sstigma 3-lobed, lobes ca.1 mm long.
Fruits (capsules): 7-1 (-12) mm long, 9-14 mm wide, pericarp thin, with ovoid to ellipsoidal lobes.
Seeds: 1 (-2) in each capsule, 3-4 mm long, 3-3.5 mm wide, ellipsoidal to ovoid, reticulated or dotted, brown.
Phenology: In habitat it flowers from February to May. Fruit from April to November.
Taxonomy notes: N. longifolia is similar and often synonymized with Nolina parvifloraSN|33535]]SN|33540]], but N. parviflora has bracts a little longer, (up to 50 cm). On the other hand the leaves of N. parviflora are more erect, while those of N. longifolia are arched, wider, very long and once the plants form a trunk will weep to the ground. However most authors believe that these evidences are not sufficiento maintain N. parviflora and N. longifolia as distinct species. More likely they are one and the same species.
