Adansonia perrieri ist eine Pflanzenart der Gattung Affenbrotbäume (Adansonia) in der Familie der Malvengewächse (Malvaceae). Sie ähnelt Adansonia digitata, hat aber aufrechte, gelbe Blüten.
Adansonia perrieri sind mittelgroße bis große, massige, 20 bis 25 Meter (selten 30 Meter) hohe Laubbäume mit blassgrauer glatter Rinde. Ausgewachsene Blätter sind handförmig geteilt mit 5 bis 9 Teilblättern und sitzen an bis 13 Zentimeter langen Blattstielen. Die filzige Blattspreite ist verkehrt eiförmig-spatelig, 8 bis 12 Zentimeter lang und 3 bis 4,5 Zentimeter breit. Der Blattrand ist ganzrandig.
Die einzelnen Blüten sind aufrecht. Ihre Kelchblätter sind 15 Zentimeter lang und 1 bis 1,5 Zentimeter breit. Die gelbe, schmal eiförmige Blütenkrone ist 17 Zentimeter lang und 3 bis 4,5 Zentimeter breit. Die zahlreichen Staubblätter sind zu einer bis 12 Zentimeter langen Röhre mit 1,5 bis 2,5 Zentimeter langen freien Spitzen verwachsen.
Die Blütezeit reicht von November bis Dezember.
Die im Oktober und November reifenden länglichen Früchte werden bis 16 bis 22 Zentimeter lang und 8 bis 14 Zentimeter breit. Sie enthalten nierenförmige, seitlich abgeflachte Samen.
Adansonia perrieri ist endemisch an der Nordspitze von Madagaskar verbreitet. Es sind nur wenige Populationen bekannt.
Die Erstbeschreibung wurde 1960 von René Paul Raymond Capuron vorgenommen.[1] Die Art wurde zu Ehren von Henry Perrier de la Bâthie benannt.
Die Chromosomenzahl ist 2 n = 88 {displaystyle 2n=88} .
Die Früchte werden gegessen.
Adansonia perrieri wird in der Roten Liste gefährdeter Arten der IUCN als „Critically Endangered (CR)“ vom Aussterben bedroht eingestuft.[2]

Adansonia perrieri, or Perrier's baobab, is a critically endangered species of deciduous tree, in the genus Adansonia. This species is endemic to northern Madagascar.[1] It has been documented in only 10 locations, including Ankarana, Ampasindava, Loky Manambato and Montagne d'Ambre protected areas. Most populations, however, are outside of protected areas. Each location has few individuals (the largest subpopulation has 43 trees). With an estimated population of fewer than 250 mature individuals and ongoing habitat decline due to fire and cutting for charcoal and timber or clearing for mining, this species has been assessed by IUCN as Critically Endangered.[1] There are three species of baobab found in northern Madagascar, all sharing the common name "bozy".[2]
Perrier's baobab is a medium to large deciduous tree, growing to 30 m tall, occurring in evergreen rainforests and forming an important component of dry deciduous forest.[1] The trunk is roughly cylindrical and the bark a smooth, pale grey. Baobab trees have two types of shoots – long, green vegetative ones, and stout, woody reproductive ones.[2]
This is a deciduous tree, with leaves throughout the wet season (November to April) but none in the dry season. Leaves are palmately compound in mature trees, with 5 to 11 leaflets (usually 9 or more leaflets per leaf on reproductive shoots).[2] Seedlings and regenerating shoots may have simple leaves. The transition to compound leaves comes with age and may be gradual. Stipules occur at the base of the leaves, are triangular or linear and up to 15 mm long. In most baobabs, stipules are soon shed, but they are persistent in A. perrieri.[2]
Baobabs have large, showy flowers that in Perrier's baobab emerge with or just before the leaves, flowering November to December. Flowers are born near the tips of reproductive shoots, in the axils of the leaves. There is usually only a singe flower in an axil, but sometimes flowers occur in pairs. The flowers are reproductive for a maximum of 15 hours. They open around dusk; opening so quickly that movement can be detected by the naked eye and are faded by the next morning.[2] The flower is made up of an outer 5-lobed calyx, and an inner ring of petals set around a fused tube of stamens.[2] The calyx is green with short stiff hairs outside and cream or pinkish with long, soft hairs inside.[2] It is made up of 5 lobes that in bud are joined almost to the tip. As the flower opens, the calyx lobes split apart and become coiled or bent back (reflexed) at the base of the flower. Sometimes the lobes do not separate cleanly, distorting the shape of the flower as they bend back. The calyx lobes remain fused at the base, leaving a feature (calyx tube) that has nectar-producing tissue and fits tightly around the petal base.[2] The flowers have a long, narrow central tube (staminal tube) made up of fused filaments (stalks of stamens), with around 200 unfused filaments above. A densely hairy ovary is enclosed in the staminal tube with a long style tipped with a red or pink stigma emerging from the filaments. Petals are set near the base of the staminal tube and are pale yellow, becoming darker with age.[2] Flowers of Perrier's baobab are pollinated primarily by long-tongued hawkmoths (Coelonia solani and Xanthopan morganii).[2]
The fruits are large (up to 25 cm long), oblong to egg-shaped and berry-like. They are ripe in October and November. They have a tough 8–9 mm thick outer wall and hold kidney-shaped seeds in a dry, pulpy matrix. The fruits are buoyant and at least in some populations may be dispersed by floating along water courses.[2]
Fruits are collected for their edible pulp,[2] and trees are cut for charcoal or timber.[1]
The specific Latin epithet of perrieri refers to the French botanist Joseph Marie Henry Alfred Perrier de la Bâthie (1873–1958), who studied plants in Madagascar.[3] It was first described and published in Notul. Syst. (Paris) Vol.16 on page 66 in 1960.[4]

El baobab de Perrier (Adansonia perrieri) es una especie en peligro de extinción perteneciente al género Adansonia. Es originaria de Madagascar.
Es un árbol que puede alcanzar 20 m de altura. Dispone de un gran tronco cilíndrico en cuyo vértice se coloca una corona de ramas irregulares que salen a los 45 °, completamente desnudas en la estación seca. En la temporada de lluvias (de noviembre a abril) se cubren con hojas , compuesto por 5-11 folíolos obovados -elípticas, de unos 2 cm de ancho. Las flores son amplias e intensamente aromáticas, de color amarillo claro a anaranjado y eclosionan durante la noche. Florece entre los meses de noviembre y diciembre. Los frutos, en forma de huevo, son de hasta 30 cm de largo y contiene numerosas semillas reniformes.
Crece también en el norte de Madagascar donde quedan pocos ejemplares de esta especie en peligro de extinción. No supera los 15 metros de altura y puesto que está en el hemisferio sur echa hojas entre noviembre y abril, como el resto de baobabs de Madagascar.
Adansonia perrieri fue descrito por René Paul Raymond Capuron y publicado en Notulae Systematicae. Herbier du Museum de Paris 16: 66, f. 1. 1960.[2][3]
Adansonia es nombre genérico que fue otorgado en honor al botánico Michel Adanson, y perrieri significa epíteto

Il baobab di Perrier (Adansonia perrieri Capuron, 1960) è un albero appartenente alla famiglia delle Malvacee, endemico del Madagascar.[2]
L'epiteto specifico è un omaggio al botanico francese Henri Perrier de la Bâthie (1873-1958).
È un albero che può raggiungere i 30 m di altezza. Presenta un grosso tronco cilindrico al cui apice è disposta una corona irregolare di rami che si staccano a 45°, del tutto spogli nella stagione secca.
Nella stagione umida (da novembre ad aprile) si ricoprono di foglie, composte da 5-11 foglioline obovate-ellittiche, larghe circa 2 cm.
I fiori, grandi ed intensamente profumati, sono di colore dal giallo chiaro all'arancio e si schiudono durante la notte. Fiorisce tra novembre e dicembre.
I frutti, di forma ovoidale, sono lunghi sino a 30 cm e contengono numerosi semi reniformi.
Questa specie è segnalata in appena 5 località del Madagascar settentrionale (provincia di Antsiranana); la popolazione più numerosa, ubicata nei pressi di Ambondromifehy, è di poco più di una dozzina di esemplari.[1]
La Lista rossa IUCN classifica Adansonia perrieri come specie in pericolo critico di estinzione (Critically Endangered).[1] È probabilmente la più minacciata delle specie del genere Adansonia.
Alcuni esemplari si trovano all'interno del Parco nazionale della Montagna d'Ambra e della Riserva speciale dell'Ankarana.
