The plant grows up to 0.4 m (1.3 ft). The flowers are white, pedicellate, with six obovate petals and bloom from May to July. [3] After it flowers, it bears dark blue/purple fruit with a white powdery coating from June to August. [4] Its stems are terete and grow 30–60 cm (12–24 in) long.
The villi begin to branch and contain blood vessels of the embryo. Other villi, called terminal or free villi, exchange nutrients. The embryo is joined to the trophoblastic shell by a narrow connecting stalk that develops into the umbilical cord to attach the placenta to the embryo.
The habit of a plant provides important information about its ecology: that is, how it has adapted to its environment. Each habit indicates a different adaptive strategy. Habit is also associated with the development of the plant. As such, it may change as the plant grows and is more properly called its growth habit.
The connecting stalk, or body stalk, is an embryonic structure that is formed by the third week of development and connects the embryo to its shell of trophoblasts. The connecting stalk is derived from the extraembryonic mesoderm. [ 1 ]
Hibiscus trionum, commonly called flower-of-an-hour, [2] bladder hibiscus, bladder ketmia, [2] bladder weed, puarangi and venice mallow, [2] is an annual plant native to the Old World tropics and subtropics. It has spread throughout southern Europe both as a weed and cultivated as a garden plant. It has been introduced to the United States as ...
Hatiora salicornioides grows to about 1 m (3 ft) tall with an erect to pendent growth habit. Its stems are composed of segments 1.5–5 cm (0.6–2.0 in) long. Each segment is shaped like a club or bottle, with the narrower end at the base. The stems branch from the end of a segment, with up to six branches forming a whorl.
Datura innoxia is quite similar to D. metel, to the point of being confused with it in early scientific literature. D. metel is a closely related plant, believed until recently to be of Old World provenance (though now thought to have been brought to Asia from the Antilles no earlier than the sixteenth century) and misconstrued as being referred to in the works of Avicenna in eleventh century ...
Intestinal villi (sg.: villus) are small, finger-like projections that extend into the lumen of the small intestine. Each villus is approximately 0.5–1.6 mm in length (in humans), and has many microvilli projecting from the enterocytes of its epithelium which collectively form the striated or brush border .
