Bactris is a genus of spiny palms which is native to the Mexico, South and Central America and the Caribbean.
 Most species are small trees about 2 m tall, but some are large trees while others are shrubs with subterranean stems.
 They have simple or pinnately compound leaves and yellow, orange, red or purple-black fruit.
 The genus is most closely related to several other spiny palms—"Acrocomia", "Aiphanes", "Astrocaryum" and "Desmoncus".
 The fruit of several species is edible, most notably "B. gasipaes", while others are used medicinally or for construction.
This is a list of Aiphanes species.
 "Aiphanes" is a genus of spiny palms which is native to tropical regions of South America, Central America, and the Caribbean.
Aiphanes is a genus of spiny palms which is native to tropical regions of South and Central America and the Caribbean.
 There are about 26 species in the genus (see below), ranging in size from understorey shrubs with subterranean stems to subcanopy trees as tall as 20 m .
 Most have pinnately compound leaves (leaves which are divided into leaflets arranged feather-like, in pairs along a central axis); one species has entire leaves.
 Stems, leaves and sometimes even the fruit are covered with spines.
 Plants flower repeatedly over the course of their lifespan and have separate male and female flowers, although these are borne together on the same inflorescence.
 Although records of pollinators are limited, most species appear to be pollinated by insects.
 The fruit are eaten by several birds and mammals, including at least two species of amazon parrots.
The Maputaland-Pondoland bushland and thickets is one of the ecoregions of South Africa.
 It consists of the montane shrubland Biome.
 The ecoregion occupies the foothills of the Drakensberg mountains, covering an area of 19,500 km2 in South Africa's Eastern Cape and KwaZulu-Natal provinces.
 It is bounded on the east by the KwaZulu-Cape coastal forest mosaic, which lies in the humid coastal strip along the Indian Ocean; to the west it is bounded by the higher-elevation Drakensberg montane grasslands, woodlands and forests.
 To the south, it transitions to the drier Albany thickets, which are characterized by more succulent and spiny plants.
Aiphanes minima is a spiny palm tree which is native to the insular Caribbean from Hispaniola to Grenada, and widely cultivated elsewhere.
 Usually 5 - tall, it sometimes grows as an understorey tree and only 2 m in height.
The Cairo spiny mouse ("Acomys cahirinus"), also known as the common spiny mouse, Egyptian spiny mouse, or Arabian spiny mouse, is a nocturnal species of rodent in the family Muridae.
 It is found in Africa north of the Sahara, where its natural habitats are rocky areas and hot deserts.
 It is omnivorous and feeds on seeds, desert plants, snails, and insects.
 It is a gregarious animal and lives in small family groups.
Cymbalaria is a genus of about 10 species of herbaceous perennial plants previously treated in the family Scrophulariaceae, but recently shown by genetic research to be in the much enlarged family Plantaginaceae.
Aiphanes horrida is a palm native to northern South America and Trinidad and Tobago.
 "Aiphanes horrida" is a solitary, spiny tree.
 In the wild it grows 3–10 metres tall (9–30 feet) tall with a stem diameter of 6–10 centimetres (2–4 inches); cultivated trees may be as much as 15 m (49') tall with a 15 cm (6") diameter.
 The epicarp and mesocarp of the fruit are rich in carotene and are eaten in Colombia, while the seeds are used to make candles.
 In parts of the Colombian Llanos endocarps are used to play games.
The golden spiny mouse ("Acomys russatus") gets its name from the reddish-orange spiny fur that covers it body from head to tail.
 This coarse, inflexible fur is thought to protect it from predation.
 Aside from the golden fur that covers its head and upper parts, its flanks are yellow and its underside is pale.
 It has gray legs with pale feet and black soles.
 It is also described as having a small, but distinct white spot under each eye.
 It is often found in the wild missing a part or all of its tail because it is able to shed this as a defense mechanism.
 However, it is not known how this is done, how often it can occur, or under what conditions.
 It lives an average of three years in the wild.
 It is omnivorous and feeds on seeds, desert plants, snails, and insects.
 Living in desert regions, it is a xeric animal that obtains water from the plants that it eats and produces very concentrated urine in order to conserve water.
 "A. russatus" is naturally nocturnal, but adapts to being diurnal when it shares a habitat with "A. cahirinus".
Aiphanes acaulis is a spiny palm endemic to western Colombia.
 it is acaulescent, as the specific epithet ""acaulis"" implies, – that is, the stem is short to the extent that it is difficult to see at all, and mostly subterranean.
 Plants have 8 to 10 leaves which are up to 1.5 metres (5 feet) long.
 The flowers are purple and are borne on an erect inflorescence.

Question: Are Aiphanes and Cymbalaria both spiny plants?
