Exempel på hur du använder STAMEN i en mening

• Synapomorphies (a character that is shared by two or more groups through evolutionary development) include the presence in the plants of oligosaccharide inulin, a nutrient storage molecule used instead of starch; and unique stamen morphology.
• Connective (botany), in the stamen of flowers, the sterile tissue that connects the anther chambers to one another and to the filament.
• A stamen typically consists of a stalk called the filament and an anther which contains microsporangia.
• There is one fertile stamen and two staminodes, which are often joined into a petal-like labellum, a structure that is inconspicuous in some species and quite showy in others.
• Many species have only a single stamen and that stamen has only a single locule, an oddity they share only with the genus Canna.
• The female flower has a small anther (‘without pollen’) and a short stemmed sari, whereas, the male flower has a long dangling stamen around the vestigial ovary.
• The classification of Salvia has long been based on the genus' unusual pollination and stamen structure, which was presumed to have evolved only once.
• Its pistils have a recurved style and a three lobed anther and each flower has 5 stamen, 5 petals, and 5 sepals.
• A small species; green foliage, oval shaped, white margin, branching habit; spikes of flowers are erect, self-coloured pink, staminodes are long and narrow, edges regular, labellum is pink, stamen is pink, style is pink, petals red with farina, fully self-cleaning; fertile both ways, self-pollinating and also true to type, capsules ellipsoid; rhizomes are thick, up to 3 cm in diameter, coloured white and pink; tillering is prolific.
• Flower parts occur in multiples of four (tetramerous), but the four tepals are fused into a long, narrow perianth-tube topped by a closed cup (the limb); the filament of each stamen is fused along its entire length with the midrib of a tepal, so that the anthers appear almost sessile, trapped within the limb; and the four carpels form a single compound pistil, the apex of which is also trapped within the limb.
• Their rarely seen flowers originate from a cavity on the upper surface of the frond, and each flower has one stamen and one pistil.
• Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positioned so that the pollen can land on the flower's stigma.
• The floral formula is ✶ K4 A4+4+1* G0 for staminate (the apical stamen /*/ may not be present) and ✶ K4 A0 (4) for pistillate flowers.
• Ray florets in the Symphyotrichum genus are exclusively female, each having a pistil (with style, stigma, and ovary) but no stamen.
• The copper plate from this early botanical treatise adds the following details: Figures 3 and 4, the male fertilizing organ (stamen) composed of filaments capped by pollen-containing anthers; Figures 5 and 6, the flower's female reproductive part (pistil), containing a cup-like ovary topped by pollen-receptive tip (stigma), whole and cut lengthwise; Figures 7 and 8, the mature berry (ovule) protected by outer petals and sepals, whole and sliced; and Figures 9 through 12, the mature berry holding seed, natural size and enlarged, then sliced on two axes.
• The original describers of the species, Aaron Goldberg and Cirilo Nelson, considered that each staminate flower was basically just a single stamen, with a flattened filament about 3–5 mm long grading into an anther about 2.
• Canna Italian Group 'Roma' is a tall aquatic Italian Group cultivar, equally at home as a water marginal or in the border; large green foliage, oval shaped, white margin, upright habit; round stems, coloured green & purple; flowers are open, yellow with orange blotches, throat red-orange, staminodes are large, edges lightly frilled, stamen is orange-red, petals red, fully self-cleaning; seed is sterile, pollen is low fertile; rhizomes are long and thin, coloured white and pink; tillering is prolific.
• Canna 'Bengal Tiger' is an Italian Group canna cultivar with variegated foliage; plant height 190 cm; foliage height 140 cm; upright stems and gently spreading leaves; ovoid foliage, background of green (137A); veins variegated yellow (mostly 13B), but paler in places (13D); maroon edge to leaf; staminodes, labellum and stamen bright orange (28B) blushed a darker, reddish (32A) in places; yellow (15A) on edges; stigma deep orange-red; petals strongly flushed red.
• Wallace' is a medium sized, Crozy Group canna cultivar; green foliage, oblong shaped, white margin, spreading habit; round stems, coloured green; flowers are open, pale yellow with red spots, staminodes are large, edges regular, stamen is rose-red with small yellow flecks; fertile both ways, not self-pollinating or true to type, capsules round; rhizomes are thick, up to 3 cm in diameter, coloured white and pink.
• The sepal, petals and stamen have a similar structure and form to the red poppy (Papaver rhoeas), except the sepals are not hairy.
