Question: What countries do the genus Calamusu and Asperula both grow in?

full_context: Document 1: Galiasperula: × " Galiasperula is a monotypic genus of flowering plants in the Rubiaceae family. The genus contains only one species, i.e. Galiasperula ferdinandi-coburgii", which is a hybrid of "Asperula" and "Galium". It is found in Greece.
Document 2: Calamus (palm): Calamus is a genus of the palm family Arecaceae. These are among several genera known as rattan palms. There are an estimated 400 species in this genus, all native to tropical and subtropical Asia, Africa, and Australia. They are mostly leaf-climbing lianas with slender, reedy stems. To aid scrambling some species have evolved hooks on the underside of the midrib, or more commonly by modified "pinnae" or tendrils in the form of stout, backward-pointing spines. These stems may grow to lengths of 200 metres.
Document 3: Arecaceae: The Arecaceae are a botanical family of perennial climbers, shrubs, acaules and trees commonly known as palm trees (owing to historical usage, the family is alternatively called Palmae). They are flowering plants, a family in the monocot order Arecales. Currently 181 genera with around 2600 species are known, most of them restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts.
Document 4: Asperula: Asperula, commonly known as woodruff, is a genus of flowering plants in the Rubiaceae family. It contains about 195 species and has a wide distribution area from Europe, northern Africa, temperate and subtropicale Asia to Australasia.
Document 5: Climbing palm: Climbing palms are genera in the family Arecaceae that grow as lianas. "Initially erect, the slender stems seek out trees for support and climb up into the forest canopy by means of recurved hooks and spines growing on the stem, leaves and inflorescences. In all climbing palms the leaves are pinnate and grow along the stem instead of forming a dense crown. The stems of climbing palms, more often referred to as canes, are solid in contrast to bamboo poles which are almost always hollow." "The majority of climbing palms are also clumping palms <nowiki>[and sympodial]</nowiki>, sending out new shoots from <nowiki>[below ground as suckers]</nowiki>." "About 600 species of palms in <nowiki>[16]</nowiki> genera have a climbing growth habit. Most noteworthy is the genus "Calamus"--the largest genus in the palm family with approximately 350 described species--source of nearly all commercial rattan."
Document 6: Pandanus: Pandanus is a genus of monocots with some 750 accepted species. They are palm-like, dioecious trees and shrubs native to the Old World tropics and subtropics. Common names include pandan ( ), screw palm, and screw pine. They are classified in the order Pandanales, family Pandanaceae.
Document 7: Acorus calamus: Acorus calamus (also called sweet flag or calamus, among many common names) is a tall perennial wetland monocot of the Acoraceae family, in the genus "Acorus".
Document 8: Arenga: Arenga is a genus of palms, native to Southeast Asia, southern China, New Guinea, and northern Australia. They are small to medium-sized palms, growing to 2–20 m tall, with pinnate leaves 2–12 m long. Arenga palms can grow in areas with little sunlight and relatively infertile soil.
Document 9: Ruscus: Ruscus is a genus of six species of flowering plants, native to western and southern Europe (north to southern England), Macaronesia, northwest Africa, and southwestern Asia east to the Caucasus. In the APG III classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). Like many lilioid monocots, it was formerly classified in the family Liliaceae.
Document 10: Asperugalium: x " Asperugalium" was a genus of flowering plants in the Rubiaceae family but is no longer recognized. It has been sunk into synonymy with x "Galiasperula", which is an artificial hybrid of "Galium" and "Asperula".
Document 11: Borassus: Borassus (Palmyra palm) is a genus of five species of fan palms, native to tropical regions of Africa, Asia and New Guinea. These massive palms can grow up to 30 m high and have robust trunks with distinct leaf scars; in some species the trunk develops a distinct swelling just below the crown, though for unknown reasons. The leaves are fan-shaped, 2–3 m long and with spines along the petiole margins (no spines in "B. heineanus"). The leaf sheath has a distinct cleft at its base, through which the inflorescences appear; old leaf sheaths are retained on the trunk, but fall away with time. All "Borassus" palms are dioecious, with male and female flowers on separate plants; male flowers are less than 1 cm long and in semi-circular clusters, sandwiched between leathery bracts in pendulous catkins; female flowers are 3–5 cm wide, globe-shaped and solitary, sitting directly on the surface of the inflorescence axis. The fruits are 15–25 cm wide, roughly spherical and each contain 1-3 large seeds. Depending on species, fruit color varies from black to brown, yellow or orange; the fibrous pulp is aromatic and sweet to taste. Each seed is enclosed in a woody endocarp, which protects it when the fruit is consumed by elephants, monkeys and other frugivores. At germination, the young seedling extends downwards into the soil and only a few leaves are visible above ground; this provides some protection against frequent fires in its savanna habitat; after an indeterminate number of years (the establishment phase), the seedling forms a stem and quickly grows above the savanna vegetation, where it is then less vulnerable to fire.
Document 12: Ravenala: Ravenala is a genus of flowering plants with a single species, Ravenala madagascariensis, commonly known as traveller's tree or traveller's palm, from Madagascar. It is not a true palm (family Arecaceae) but a member of a monocotyledonous flowering plant family, Strelitziaceae. The genus is closely related to the southern African genus "Strelitzia" and the South American genus "Phenakospermum". Some older classifications include these genera in the banana family (Musaceae). Although it is usually considered to be a single species, four different forms have been distinguished.
Document 13: Asparagus (genus): Asparagus is a genus of flowering plants in the family Asparagaceae, subfamily Asparagoideae. It comprises up to 300 species. Most are evergreen long-lived perennial plants growing from the understory as lianas, bushes or climbing plants. The best-known species is the edible "Asparagus officinalis", commonly referred to as just "asparagus". Some other members of the genus, such as "Asparagus densiflorus", are grown as ornamental plants.
Document 14: Rubieae: Rubieae is a tribe of flowering plants in the Rubiaceae family and contains 969 species in 14 genera. The genus "Galium" is responsible for more than two thirds of the species in the tribe. The second largest genus is "Asperula", which contains about 200 species. Unlike the rest of the Rubiaceae family, the tribe contains predominantly perennial and annual herbs with pseudowhorls of leaves and leaflike stipules and is centered in temperate and tropical-mountain regions.
Document 15: Asperula arvensis: Asperula arvensis, known as blue woodruff, is a species of flowering plant in the Rubiaceae family. It belongs to the genus "Asperula". It is native to most of Europe plus Algeria, Morocco, and southwest Asia from Turkey to Kyrgyzstan.
