Annals of the Royal Botanic Garden Calcutta. Asiatic Palms - Lepidocaryeae Part I - The Species of Calamus

1908

The incompleteness of the specimens of Calami the difference between the male and female spadices or between the flowers and the fruit and iu particular the not infrequent fact that the spadices in herbaria are not from the same plant as the associated leaves have led even the most experienced botanists to propose a few non-existent species: nor am I certain that the present work is entirely f [...] Not infrequently the spines especially when rather strong leave on the surface of the sheaths or oven on the underside of the leaf-rachis a more or less distinct and deep impression of their outline ; this is due to the fact that when the leaves are closely packed in the terminal shoot the spines are turned upwards and aro pressed against the surface of the organ from which they originate whi [...] In the description of the species the term rachis is applied only to that part of the axis of the leaves which bears leaflets it having been decided to term the basal naked portion of the leaf-axis the petiole and the prolongation of the axis beyond the distal leaflets when this occurs the cirrus. [...] When a Calamus has hooked prickles or claws on the leaf-rachis on the primary spathes and the axial parts of the spadix the plant is nevertheless scandent even if there be no cirrus at the end of the leaf since the clawed leaf-rachis together with the leaf-sheath flagella with which in this case the plant is provided take the place of the cirri and perform the functions of climbing organs. [...] The point of insertion of the spadices as of the flagella on the leaf-sheaths is frequently marked by a distinct swelling or callosity and as we have already seen in discussing the leaf-sheaths a slightly raised ridge which marks the course of the fibro-vascular bundles that pass from the stem into the spadices often also runs downward along the whole length of the sheath.
