Are both Calodendrum and Echeveria genus of trees?
no
Calodendrum
Calodendrum is a genus of medium-sized evergreen trees comprising two species from Africa. "
Calodendrum capense" (Cape Chestnut) is a well known tree that is widely cultivated, while "Calodendrum eickii" is a rare forest tree from Tanzania.
 The botanical name comes from Greek, "kalos" means beautiful and "dendrum" means tree.
 Both species are harvested for their timber in Africa.
Echeveria
Echeveria is a large genus of flowering plants in the Crassulaceae family, native to semi-desert areas of Central America, Mexico and northwestern South America.
Alphitonia
Alphitonia is a genus of arborescent flowering plants comprising about 20 species, constituting part of the buckthorn family (Rhamnaceae) of the rosid eudicots.
 They occur in tropical regions of Southeast Asia, Oceania and Polynesia.
 These are large trees or shrubs.
 In Australia, they are often called "ash trees" or "sarsaparilla trees".
 This is rather misleading however; among the flowering plants, "Alphitonia" is not closely related to the true ash trees ("Fraxinus" of the asterids), and barely at all to the monocot sarsaparilla vines ("Smilax"). Spruce
A spruce is a tree of the genus Picea , a genus of about 35 species of coniferous evergreen trees in the family Pinaceae, found in the northern temperate and boreal (taiga) regions of the earth.
 Spruces are large trees, from about 20–60 m (about 60–200 ft) tall when mature, and can be distinguished by their whorled branches and conical form.
 The needles, or leaves, of spruce trees are attached singly to the branches in a spiral fashion, each needle on a small, peg-like structure.
 The needles are shed when 4–10 years old, leaving the branches rough with the retained pegs (an easy means of distinguishing them from other similar genera, where the branches are fairly smooth). Cola (plant)
Cola is a genus of trees native to the tropical rainforests of Africa, classified in the family Malvaceae, subfamily Sterculioideae (or treated in the separate family Sterculiaceae).
 Species in this genus are sometimes referred to as Kola tree or Kola nut for the caffeine-containing fruit produced by the trees that is often used as a flavoring ingredient in beverages.
 The genus is related to the South American genus "Theobroma", or cocoa.
 They are evergreen trees, growing up to 20 m tall (about 60 feet), with glossy ovoid leaves up to 30 cm long and star shaped fruit. Tilia
Tilia is a genus of about 30 species of trees native throughout most of the temperate Northern Hemisphere.
 Commonly called lime trees in the British Isles, they are not related to the lime fruit.
 Other names include linden, and basswood for the North American species.
 The genus occurs in Europe and eastern North America, but the greatest species diversity is found in Asia.
 Under the Cronquist classification system, this genus was placed in the family Tiliaceae, but genetic research summarised by the Angiosperm Phylogeny Group has resulted in the incorporation of this genus, and of most of the previous family, into the Malvaceae. Tibouchina
Tibouchina Aubl.
 is a Neotropical flowering plant genus in Melastomataceae Juss.
 that contains approximately 240 species.
 Species of this genus are herbs, shrubs or trees and typically have purple flowers.
 They are native to Mexico, the Caribbean, and South America where they are found as far south as northern Argentina.
 Members of this genus are known as glory bushes, glory trees or princess flowers.
 The name "Tibouchina" is adapted from a Guianan indigenous name for a member of this genus .
 A recent systematic study has shown that this genus is paraphyletic. Mora (plant)
Mora is a genus of large trees in the subfamily Caesalpinioideae of the legume family Fabaceae, (or in some classifications the family Caesalpinaceae of the order Fabales).
 There are seven to ten species, all native to lowland rainforests in northern South America, southern Central America and the southern Caribbean islands.
 These are large, heavily buttressed rainforest trees up to 130 feet (40 meters) in height (to 200 feet (61 meters) in the case of M. excelsa ).
 The genus is particularly noteworthy for the exceptional size of its beans, which are commonly acknowledged to be the largest known dicot seeds, in the instance of M megistosperma being up to seven inches (18 cm) in length, six inches (15 cm ) in breadth and three inches (8 cm)in thickness, and a weight of up to 2.2 pounds (1000 grams).
 The beans of Mora spp.
 are edible if boiled, and are also the source of a red dyestuff.
 The species M. excelsa is one of the few rainforest trees to grow in pure stands. Cinnamomum
Cinnamomum is a genus of evergreen aromatic trees and shrubs belonging to the laurel family, Lauraceae.
 The species of "Cinnamomum" have aromatic oils in their leaves and bark.
 The genus contains over 300 species, distributed in tropical and subtropical regions of North America, Central America, South America, Asia, Oceania, and Australasia.
 The genus includes a great number of economically important trees. Echeveria lilacina
Echeveria lilacina, common name Ghost Echeveria or Mexican Hens and Chicks, is a species of succulents in the genus "Echeveria" belonging to the family Crassulaceae.
 The genus name "Echeveria" was given in honor of the 18th century Mexican botanist and painter Atanasio Echeverría y Godoy, famous for his paintings of plants.
