All of these Shoreas, 8 . leprosula, S. rigida, S. macro p-tera, and S. bracteolata, have epigeal cotyledons with short petioles;but the Indian 8. robusta, Roxb., differs greatly from them inhaving cotyledons capable of being hypogeal, with greatly elongat-ing petioles, in which characters it approaches Dipterocarpus. In the Botanic Gardens, Singapore, where S. macroptera isparticularly abundant, many abnormal seedlings appeared in of these had three cotyledons, followed by three leaves in awhorl: some had three cotyledons followed by what may be calledtwo and a half leaves (fig. 15) or by three and a half leaves(figure 16) ; and sometimes abnormally split leaves would followthe normal number of cotyledons (fig. 17). Notice was particular-ly taken of these in the wish to ascertain how Anisoptera (see thisJournal p. 44) has a whorl of four leaves following the cotyledons. KALEVIM
