Abstract

Cabralea canjerana (Vell.) Mart. is a tree that occurs frequently in secondary forests of Maringá, Paraná, Brazil and presents a valuable wood. Its flowering time occurs from August to October and the anthesis occurs during the night. Its flowers are visited by Lepidoptera-Noctuidae. The flowers are unisexual and solitary or arranged in panicles. The perianth presents a papillose epidermis with striate cuticle and a parenchymatic mesophyll. Ten stamens constitute the androecium and are arranged in a staminal tube with anthers. The anthers present epidermis, endothecium, two median layers and secretory tapetum with binucleate cells. The semi-inferior ovary presents anatropous, bitegmic and crassinucleate ovules. The nectaries are located in the base of the ovary and staminal tube and they present papillose epidermis with stomata and secretory parenchyma with a conspicuous phloematic tissue.

摘要

卡布拉雷阿樟(Cabralea canjerana (Vell.) Mart.)是一种常见于巴西巴拉那州马林加次生林的树木,其木材具有很高的价值。它的花期为8月至10月,开花发生在夜间。其花朵会吸引鳞翅目夜蛾科昆虫。花为单性,单生或排列成圆锥花序。花被具有具乳头状表皮和条纹状角质层以及薄壁叶肉。十枚雄蕊构成雄蕊群,排列成带有花药的雄蕊管。花药具有表皮、药室内壁、两层中层和具双核细胞的分泌型绒毡层。半下位子房具倒生、双珠被和厚珠心胚珠。蜜腺位于子房基部和雄蕊管,具有具气孔的乳头状表皮和带有明显韧皮组织的分泌薄壁组织。
