Waheshimwa wataalam mmeuona mmea wenyewe? Tupeni manondo basi.
Haya mkuu nimejaribu kwa uwezo wangu kutafuta. Botanist anasema pixel hazionekani vizuri (ile reflection ya light) ila anasema inawezekana ni
Macaranga kilimandscharica (Baill.) Benth. ex Sim. Anasema ikiwa ni mti wa asili basi probably utakuwa ni huo Macaranga la kama ni exotic (mti ambao sio wa asili kwa maeneo yetu) hasa atahitaji maelezo zaidi ili kuufahamu. Conclusively, anasema ni Macaranga kilimandscharica.
Note: Utoe senksi please
Maelezo ya ziada ni kama ifuatavyo;

Botany
Macaranga kilimandscharica is a small to medium semi-deciduous tree 4.5-18 m, or large tree up to 27 m, often with a pyramidal crown, much branched, branches ascending, or with a broad, spreading crown. Bark green at first, later becoming greyish white, light or dark grey. Stem smooth or longitudinally striated or fluted, with fluted stems. Young shoots and inflorescence-axes densely ferruginous tomentellous at first, later glabrescent.
Leaves triangular-ovate, base cuneate, rounded, truncate or rarely subcordate, occasionally peltate, apex acuminate, 5-15 cm x 3-10 cm. 3-7 nerved from the base, rusty -tomentellous but glabrescent, densely glandular-punctate beneath.
Inflorescence 2-10 cm long, cyathia yellow-green. Male inflorescence paniculate, bracts ovate-lanceolate, 8-15 cm long, 2-3 mm wide, male flowers subsessile, stamens 2, filaments fused basally, anthers obscurely 4-thecous, 0.5 mm across. Female inflorescence racemose to subpaniculate, female flower pedicels 1-2 mm long, calyx cupular splitting into 2-3 lobes which flatten as the fruit matures, ovary 1-2 lobate, 1-1.5 mm long, 1-2 mm wide, densely yellowish granulate-glandular.
Fruit dull green, subglobose or 2-lobed, 4-6 mm x 5-11 mm densely glandular, 1-seeded.
M. kilimandscarica is placed in the tribe Acalypheae and has close affinities with the genus Acalypha.
The generic name is after a Madagascan native name and the specific epithet kilimandscharica refers to Mt. Kilimanjaro area of Tanzania.
Domestication
This species features in indigenous agroforestry systems, M. kilimandscharica is one of the preserved species in traditional forest reserves of the Nyakyusi of Tanzania , and a component of the complex multistoreyed Chagga homegardens and an significant coffee shade tree in the Ethiopian highlands.
Ecology
M. kilimandscharica is a fast growing pioneer species of montane evergreen forest, and may be locally common to dominant in wetter vegetation types. It regenerates vigorously in clear-felled areas, secondary forest, forest edges, riverine forest and disturbed places. Usually associated with Albizia gummifera, Polyscias fulva or Vernonia subuligera, it often replaces selectively logged Ocotea usambarensis.
Biophysical limits
Altitude: 1 300-3 000 m, Mean annual rainfall: 1 500-2 500 mm, Mean annual temperature: 18-26 deg.C
Soil type: Loamy well drained soils.
Native Range
Democratic Republic of Congo, Ethiopia, Kenya, Malawi, Rwanda, Sudan, Tanzania, Uganda, Zambia

Reproductive Biology
M. kilimandscharica is a dioecious prolific seeder. Three species of turacos the great blue turaco (Corythaeola cristata), the Ruwenzori turaco (Musophaga johnstoni) and the black-billed turaco (Tauraco schuettii) reportedly disperse over 80% of ingested seeds away from parent trees.
Propagation Methods
Direct seeding and use of wildings are the most preferred propagation methods for M. kilimandscharica.
Tree Management
M. kilimandscharica is a fast growing tree with little management needs once established. When still young care should be offered against injury and drought.
Products
Fuel: Macaranga is used as a firewood source.
Timber: Wood pink, soft, straight grained; weight 54-68 kg/cu ft, difficult to saw and apt to split in seasoning. Has been used for boxes and crates in Kenya.
Medicine: Root extracts are drunk for bilharzia treatment, the root decoction is drunk as a cough remedy and the leaf decoction for stomach ailments.
Services
Erosion control: This is a useful pioneer species with potential use in protecting soils on logged sites.
Shade or shelter: M. kilimandscharica has a broad dense crown providing deep shade.
Soil improver: Leaf litter from the tree enriches surrounding soil.
Boundary or barrier or support: Dry wood from macaranga have been used for fencing.
Intercropping: Regeneration of Ocotea usambarensis is good under M. kilimandscharica. Macaranga is one of the species used in the complex multistoreyed Chagga homegardens. The high species diversity in these gardens minimises drought, pest and economic risks associated with monocultural farm systems. The species is also used as a coffee shade tree in the Ethiopian highlands.
