Wood Anatomy of 8 genera of Indian Flacourtiaceae has been described in detail. The study indicates that type of ray-vessel pitting and perforation plate are of diagnostic value in separating the genera Hydnocarpus and Gynocardia. The remaining genera have more or less similar anatomical features. However the important anatomical features have been tabulated for facilitating specific identification.

Wood Anatomy of the Indian Myristicaceae viz. Gymnacranthera, Horsfieldia, Knema and Myristica has been described in detail. The study indicates that the four Indian genera can be easily distinguished from each other on the basis of their wood structure. Woods of some foreign genera both African and American have also been investigated for a better understanding of their relationship with the Asiatic members Of the family and to confirm certain observations made by earlier workers. The occurrences of reticulate, irregular anastomosing type of vesselperforations in Pycnanthus and scalariform type in Cephalosphaera (both African genera) has been recorded for the first time Observations also show that oil cells and crystals in the rays are completely lacking in the, African and Indian representatives. Other observations which are contrary or in agreement to the findings of the earlier workers have also been recorded.- Wood Anatomy of Indian Species of Michelia with Particular Reference of their Identification

The wood structure of eight Indian specics of Michelia have been studied in detail with a view of determining features of diagnostic value for their identification. The study indicate that various anatomical characters viz. frequency, size and shape of vessels, presence/absence of oil cells in rays and presence/absence of spirals in vessels are likely of value for their specific delimitation. A tentative key has also been given.Full Text

Anatomical studles carried out on Boswellia serrata Roxb, Garuga pinnata Roxb., Lannea coromandelica Merr. and Spondias pinnata Knrz. with a view to ascertaining the diagnostic value of radial gum canals and cell inclusions indicate that features like size and frequency of gum canals, nature of epithelial cells and cell inclusions i e, occurrence of crystals and silica are likely to be of diagnostic value in identification of woods of these species.- Wood Structure of Clethra monostachya Rehder and Wilson

The nature and pattern of distribution of tension wood in rubber wood (Hevea brasiliensis Muell Arg.) has been studied. The studies indicate that tension wood in this species can best be recognized under the microscope only. It has been found to occur both as diffuse and in bands. Staining reactions indicate that it is the S3 (G) layer which is gelatinised and non-lignified. Further, the proportion of tension wood has been found to vary in different planks representing different trees and also along the length within the planks. This erratic distribution of tension wood may be responsible for causing warping of the match splints.- Studuis on the Effects of Spacing and Application of Fertilisers on Wood Quality in Eucalyptus tereticornis Sm.

The results of the study on the effect of spacing and application of fertilise on wood specific gravity, fibre rength and tree groth in 8-year-old experimental plantations of Eucalyptus tereticornis Sm. Laid out in West Bengal and Gujarat are reported here. Spacing as well as application of fertilisers do not show any significant effect on specific gravity. Though the fibre length has heen found to differ significantly among the treatments, the trend is not consistent for any of the treatments in the two localities. While close spacing adversely affect the height and girth of the trees. The effect of application of fertilisers is not significant.- A Note on the Occurrence of Radial Vessels in Combretum latifolium Bl.
