Author of several books, his magnum opus was "A Manual of Indian Timbers". He was also the author of many papers on forestry and botanical subjects in the "Indian Forester", of which he was a founding editor. Another major work was the "Flora of the Presidency of Madras" (1915) of which five parts were published during his lifetime and he was working on the seventh at the time of his death. This was a major work and required obtaining specimens from the botanical gardens at Calcutta, the forest herbarium at Travancore, the Agricultural College at Coimbatore and the Royal Botanic Garden at Edinburgh. He also made use of the specimens in the Madras Herbarium at Kew presented by Sir Alfred Gibbs and Lady Bourne. The work was completed by C.E.C. Fischer. It remains a major guide for the region.
