Flowers are yellow-green, 2.5 mm in diameter, pedicels are nonparticulate;
perianth is 2 mm long; 8 nectaries are yellow, alternating with stamens, being homostyly, that is, self-pollinated flowers; stigmas are capitate.
It is perhaps the most beautiful of all, with round white
perianth and a tiny cup, greeny yellow with a red edge.
In the apical portion is placed the
perianth in decomposition (Figure 1A).
Inflorescence few to many flowered, lateral cymes or glomerules, 1.0-2.5 mm diam., bracts leaf like, 3-5 mm, elliptic, apex blunt, margins crenate-dentate;
perianth 5, greenish, erect, hirsute, glandular, 0.5-0.75 x 0.2.0.3 mm, sessile or sub-sessile; stamens 0-1, stigma 2.
This week's online offer is for 15 Daffodil Merlin, an exciting new introduction to our range which produces broad leaves and a contrasting orangeyellow
perianth.
Involvement of the Ivr2-invertase in the
perianth during maize kernel development under water stress.
The inner and outer
perianth circles are 4 to 6 mm long and elliptical to oval-elliptical.
(2011) this subgenus is characterized by more or less convolute stem leaves, appressed to the stem when dry, spreading when moist; dorsal leaf lobe longer than broad; auricles at leaf base lacking or not similar in size, the dorsal auricle distinctly larger than the ventral one, and
perianth surface smooth.
As an evolutionary old family the Annonaceae exhibit floral morphological characters which they partly share with other representatives of the order Magnoliales and further basal angiosperms, such as hermaphrodititic flowers, a usually trimerous
perianth, and numerous stamens and carpels with a helical arrangement along an elongated, mostly convex receptacle.
Male catkins with 2-4 cm, with acute
perianth lobes.
The main morphological features are focused on leaf shape and insertion, raceme length and its disposition, bract shape, relative bract length, number, shape and size of the
perianth sections and the site of insertion of the staminal filaments on the nectariferous
The segments of the
perianth are yellow with bright red bases, and the fruits are oblong, 3-6 cm long, reddish to purplish-red when mature.
Each flower is borne in a single bract (modified leaf) and has either no
perianth (floral envelope) or one reduced to a series of scales or bristles rather than showy petals.
(Equisetopsida, Magnoliidae, Asparagales, Amaryllidaceae) are terrestrial herbs, not climbing, with a subterranean bulb, umbellate inflorescence, and white
perianth. The genus encompasses 17 species distributed throughout Central and South America, ten of which occur in Colombia: E.
