myself. For the last three years I have been unable to do as much as I could wish, and this must be the excuse for the meagreness of the collection, and also for the large proportion of plants being from division IV. Those for division I. have also been collected by myself, as Marlborough is just near enough to the northern boundary of that division to enable me to collect there occasionally.

The Herbarium is still unfit to be considered in any way a county Herbarium, and I should therefore thankfully acknowledge the receipt of any contributions to it. It is clearly impossible for one person to do all this work of collecting, and as will be seen from the subjoined Table, some districts are very poorly represented, if indeed they can be considered to be represented at all.

Total No. of Species represented, 598

It will be seen that the same species is sometimes represented in more than one division, I shall be happy to send a marked list to anyone who may feel inclined to assist: but still it may be interesting to know some of the more important species which are not at all represented :

My only fear in publishing this list, long as it is, is that it may lead intending contributors to imagine that the above are all that are required. The fact is, that of Erythræa Centrurium alone are there representatives from each of the five divisions. I have merely indicated those species of which we have no representatives at all, and which cannot be easily procured near Marlborough, but as will be seen from the Table above given, every division is most inadequately represented, and I can only repeat that I shall gladly enter into correspondence with anyone who is anxious to help in the work. In conclusion and as an encouragement to intending contributors, a few of the more interesting points of the collection, as already formed, may be mentioned.

What are called the Batrachian Ranunculi will, I trust, be well

represented, and of these I shall unhesitatingly insert all good specimens which may be sent. They are the water-plants which cover the ponds in early summer with their white flowers, and present a great variety of forms. The collection already possesses several very interesting forms, and some of the species not recorded in Mr. Flower's "Flora." The ponds in which they grow often dry up in summer, yet the plants are not destroyed, but re-appear when there is sufficient water in the spring. A series from a succession of ponds on the Overton Downs will interest those who are paying attention to the subject. Specimens of Thlaspi perfoliatum, Sinapis muralis, Silene noctiflora, Caucalis daucoides, Carduus tuberosus, Cineraria campestris, Monotropa Hypopitys, Polemonium cæruleum, Orobanche elatior, Euphorbia platyphylla, Ornithogalum pyrenaicum, Alopecurus fulvus, together with some Rubi and Salices not recorded in the "Flora," will also be found, some of them quite new to the county, and not known hitherto to occur so far south. Still these are but very few of the rarities of Wiltshire, which I hope to increase ere many months have passed.
