The rosettes are persistent and conspicuous during the early development of the main stem. 2. Mature Plants.—The mature plants, m. high, have a spreading habit (Fig. 2) with long side branches. Stems chiefly green (brownish below), the papillate glands at the base of long hairs also green. Basal leaves on the main stem narrowly elliptical, about 16 cm. long (Fig. 3), leaves above lanceolate. 3. Inflorescence.—Bracts lanceolate, less than half the length of the buds (Fig. 4). 4. Buds.—About cm. long, the cone 4-angled (Fig. 4). Sepals clear green, their tips not markedly Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bussey Institution.
