Hooker "Good Heavens what insect can suck it[?]" By November, a specimen of the exotic South American Catasetum orchid Hooker had given to Darwin had shown its "truly marvellous" mechanism, by which it shot out a pollinium at any insect touching a part of the flower "with sticky gland always foremost". This plant had astonished botanists in 1836 when Robert Hermann Schomburgk stated that he had seen one plant growing three distinct flowers which usually grew separately and had wrongly been categorised as three distinct genera, namely Catasetum tridentatum, Monachanthus viridis, and Myanthus barbatus. John Lindley had remarked that "such cases shake to the foundation all our ideas of the stability of genera and species." One of Darwin's correspondents told of delight at growing a beautiful specimen of Myanthus barbatus imported from Demerara, then dismay when the plant flowered the next year as a simple Catasetum. In view of this interest, Darwin prepared a paper on Catasetum as an extract from his forthcoming book, which was read to the Linnean Society of London on 3 April 1862. Darwin solved the puzzle by showing that the three flowers were the male, female, and hermaphrodite forms of a single species, but as they differed so much from each other, they had been classified as different genera. Publication Darwin sent the incomplete manuscript to his publisher John Murray on 9 February 1862, while he was still working on the last chapter. Although anxious that the book might not sell, he could "say with confidence that the M.S. contains many new & very curious facts & conclusions". When the book was printed, he sent out presentation copies to all the individuals and societies who had helped him with his investigations, and to eminent botanists in Britain and abroad for review. On 15 May 1862 the book was published under the full title of On the Various Contrivances by Which British and Foreign Orchids Are Fertilised by Insects, and On the Good Effects of Intercrossing. In August, Darwin was "well contented with the sale of 768 copies; I shd. hope & expect that the remainder will ultimately be sold", but the book sold slowly and less than 2,000 copies of the first edition were printed. An expanded edition translated into French was published in Paris in 1870, and in 1877 Murray brought out a revised and expanded second edition, with the shortened title The Various
