The generic name Henckelia Sprengel (1817: 402) was proposed in honor of Leo F. V. Henckel von Donnersmark (1785–1861), a German administrator and passionate botanist. However, even though the genus had priority over Didymocarpus Wallich (1819: 378), in view of its wider usage the latter name was conserved (Vitek et al. 2000). Henckelia Sprengel (1817: 402) was resurrected from synonymy of Didymocarpus by Weber & Burtt (1997), separating them by an array of morphological characters, to give a more natural taxonomic unit. The genus Henckelia has about 180 species distributed from south India and Sri Lanka over Sumatra, southern Thailand, Malaya Peninsula, Borneo to the Philippines, Sulawesi and New Guinea. It accommodates most of the south Indian species formerly placed in Didymocarpus (Middleton et al. 2013). At present, 30 species are known to occur in India, of which 13 are endemic to the Western Ghats (Janeesha & Nampy 2015).

In India the economic rôle played by insects of the order Thysanoptera, popularly known as “ thrips,” has not become so conspicuous as in some other parts of the world. The different kinds of thrips affecting specific crops such as wheat, oats, tobacco, fruits, onions, cacao and hot-house plants, in Europe, America, the West Indies and many tropical areas, are insects of established notoriety, and some of them cause severe and extensive damage to valuable crops from time to time ; but so far no species of Thysanoptera has as yet gained such prominence in India. Neither Lefroy in his book on “ Indian Insect Pests ” (1904), nor Fletcher in his publication on “ South Indian Insects ” (1914), has recorded any insect of this group as a definite pest among the numerous forms listed as injurious. In his other and more voluminous text-book, “ Indian Insect Life ” (1909), however, Lefroy, in the course of a brief chapter devoted to Thysanoptera, just refers to the three Indian species which were the only ones recorded till then, viz. : Idolothrips halidayi and Phloeothrips anacardii, described by Newman in 1856, and Panchaetothrips indicus, described by Bagnall in 1912 ; and only one of these, the last, had any economic importance, having been noted on turmeric in Madras.

Modern Tool

Systematics must be perceived as a science that can hold its own image in the current information era, rather than as an old fashioned stamp collecting exercise and this perception must be presented to both the general and public.To build up a natural system of classification of plants, it is necessary to compare one form with another, such parts like stem, leaf, root, flower, fruits and seeds. These superficial examinations are helpful to a certain extent in identifying and classifying the plants. The phenotype of each and every taxon is unique and this uniqueness itself is a clear identifying feature for a taxon. To a certain extent cytological, palynological, anatomical features seen to go in hand with the external morphological features.

The present publication provides a comprehensive wood anatomical survey of woods of Indian tree species of the family Anacardiaceae. Thirtyfive species belonging to 19 genera are described as per the feature list of IAWA. Intrusive fibre cavities and perforated ray cells have been reported in Holigarna arnottiana and Pistacia terebinthus respectively. Two species, Choerospondias axillaris and Rhus hookeri, lacked helical thickening despite being ring-porous. Most tribes of the Anacardiaceae appear to be heterogeneous wood anatomically, except Semecarpeae which are homogeneous. The tribes Mangiferae and Semecarpeae are quite similar and may be placed together. Interesting findings were made regarding Indian species of Rhus, which can be divided into two groups. It is suggested to recognise Rhus Group II as a separate section. The ecological trends suggest that anatomical differentiation exists between tropical and temperate species as well as deciduous and evergreen species.
