Much of the apparent variation derives from the different ways the floral tube has been expressed. E. jambolana seeds can be used for its antibacterial, antifungal, aphrodisiac, anti-inflammatory, antioxidant, antipediculosis, and antiulcerative properties. ... Knowing the Plant Family can tell you where the seed pod will be - on the stalk side of the flower (called an Inferior Ovary - such as in Amaryllidaceae, Cannaceae) or … Economic importance includes important timber trees, especially Eucalyptus spp., edible fruits (e.g., Psidium guajava, guava), spices (e.g., Syzygium aromaticum, cloves, Pimenta dioica, allspice), oils (e.g., Eucalyptus spp. The family consists of about 85 genera and 1500 species among which 111 species found in India.

The leaves are evergreen, alternate to mostly opposite, simple, and usually entire (i.e., without a toothed margin). Ways to interest and involve students in the study of plants through flower structure have been suggested over many years (e.g., Bernadette, 1958; Flannery, 1987; Marquard & Steinback, 2009). The basic chromosome number for the genus is x = 11 and allspice is a diploid with 2n = 22 (Purseglove et al., 1981). shivanesh m November 16, … The fruit is used fresh and processed (juices, frozen pulps, jams, sweets). Flowers of seven species are also presented to show various aspects of floral structure and floral formula construction. Investigating floral structure is an important part of the biology curriculum, but students often examine only a very limited diversity of species and have limited opportunities to revise this material before examinations. In effect, long-term administration for 90 days revealed significant effects on hemoglobin, red blood cells, platelets, and granulocytes as well as an insignificant reduction of total white blood cells [90]. The Virtual Floral Formula is a Web site that lets students practice their floral structure interpretation skills using detailed dissection photographs of the flowers of 12 species. … Species of the genus Pittosporum are commonly known as Australian laurel. In most dicotyledonous plants the food conducting cells of the vascular system, the sieve elements of the phloe… The LD50 for both intraperitoneal and oral routes of the extract (263 and 2500 mg/kg, respectively) were the indications of its toxic potential [90], suggesting that its prolonged usage must be avoided (Figure 22.8). The Virtual Floral Formula Web site provides students with a unique resource for practicing their floral structure interpretation skills.
