He is not sure whether he has seen Subularia flowering above the water, but thinks it probably is an aerial flowerer, at least sometimes.

Has been unable to find an anonymous book on pigeons in the University Library.

Summary

Discusses the flora of Porto Santo in relation to that of Madeira. While these islands have some 20 endemic species in common, there are 7 or 8 species endemic to Porto Santo alone, and 25 common to Porto Santo and Europe that are not found on Madeira. Believes the great difference in soil and climate is enough to explain this: plants common on one island cannot be made to grow on the other. Believes J. D. Hooker has underestimated the number of species endemic to Madeira. There are some remarkable endemic species of common plants in the Dezertas.

The eel is the only freshwater fish on Porto Santo and Madeira.

Summary

Asks readers of Gardeners’ Chronicle to give evidence "showing either that Leguminous crops, when grown close together do sometimes cross or on the other hand that they may invariably be grown close together without any chance of deterioration".
