Abstract

The massive, terminal inflorescences of Arthrophyllum diversifolium and Arthrophyllum crassum show four orders of branching; Arthrophyllum montanum and Arthrophyllum stonei three orders of branching and Arthrophyllum alternifolium two orders of branching. The tree architecture of A. alternifolium conforms to Chamberlain's model while the other 4 species belong to Leeuwenberg's model. The structure of the pedicel in the 5 species studied is similar; the epidermis shows the presence of multicellular, glandular trichomes and the vascular tissue is composed of 10 free bundles. The vascular cylinder of the bigger inflorescence branches is made up of a varying number of free bundles and often enclosing several medullary bundles except in the secondary inflorescence branches of A. montanum and the primary inflorescence branches of A. diversifolium. Perivascular fibres occur as bundle caps other than in the secondary inflorescence branches of A. stonei. The cortex and pith are scattered with secretory ducts and druses.
