Nolinoideae is a monocot subfamily of the family Asparagaceae in the APG III system of 2009. It was previously treated as a separate family, Ruscaceae s.l.1] The family name is derived from the generic name of the type genus, Nolina.
The subfamily includes genera previously placed in a range of different families, including Ruscaceae s.s., Nolinaceae, Dracaenaceae, Convallariaceae and Eriospermaceae. Like many groups of lilioid monocots, the genera included here were once included in a wide interpretation of the family Liliaceae.[2]
A possibly incomplete list of the genera included in the Agavoideae is given below. The reference is to the source which places the genus in this subfamily. The genera currently included here
have varied widely in their limits and
assignment to families and subfamilies; some former family placements other than Agavaceae which will be found in the literature are given below.[2][3][4]
Herbs perennial, rhizomatous, monopodial.Rhizomeascendingor less often creeping, thick, stout, sometimes slightly woody. Stem very short or sometimes slightly elongate. Leaves basal or on short stem, usually distichousequitant, sometimes spaced, basally distinctly petiolate or not; leafbladelorate to ovate-elliptic. Scapeaxillary.Inflorescence a terminalspike, several to many flowered, sometimes with several sterilebractsapically; fertile bracts lanceolate to ovate, often longer than flowers, sometimes shorter. Perianthsegments 6, connate into a tube for 1/2--2/3 their length, fleshy, sometimes with a ringlike, fleshy appendage in throat; lobes often spreading, sometimes incurved,
sometimes fimbriate at margin.Stamens 6; filamentsproximallyadnate to perianth tube,
free part short to long; anthers positioned as high as or higher than stigma, dorsifixed.Ovary 3-loculed; ovules 2--4 per locule.Style 1, to 1(--3.5) mm; stigma small, 3-lobed. Fruit a berry, 1--3-seeded.[1][more]
Herbs perennial, rhizomatous, sympodial, epiphytic.Rhizome horizontally creeping, often branched, moniliform, fleshy.Stemascendingorpendulous, simple. Leaves cauline, alternate, shortly or indistinctly petiolate, entire.Inflorescencesterminal and often also
axillary, racemose or subumbellate, often 1- or 2-flowered, sometimes 3--6-flowered. Flowersbisexual, pendulous, ebracteate.Perianth pinkish or whitish, tubular or campanulate; segments 6, imbricate, subequal, connateproximally for 1/5--5/6 their length.Corona absent. Stamens 6, in 2 whorls, outer ones shorter than or equaling inner; filamentsfiliform, smooth or verrucose, proximally adnate to perianth for most of their length; antherslanceolate to ovate, introrse.Ovaryellipsoid, 3-loculed. Style slender; stigmacapitate or 3-lobed, small.Fruit a berry, orange, globose to ovoid.[2][more]
Otatea is a of clumping bamboos found from Central Mexico to Central America. The name derives from the nahuatl otatl, meaning "bamboo". The genus comprises 3 species, of which the best-known is of the Mexican weeping bamboo. [more]
