of the Parisian botanists; Koch's O. militaris is probably the same as 

 that of the ' Suppl. to Eng. Bot.' t. 2675. O. variegata has been said 

 to have been found near Rouen, but this appears to be erroneous. 

 Other plants which I observed in this walk were Lithospermum pur- 

 pureo-caeruleum, in a lane below the church at Canteleu ; Fedia ca- 

 rinata, Linaria supina, Bromus tectorum and Geranium rotundifolium, 

 almost everywhere. Sedum album was not unfrequent on the walls, 

 and Aristolochia Clematitis by the side of the lower road from Rouen 

 to Canteleu. In all this walk the scenery is delightful, commanding 

 the valley of the Seine, and a rich variety of wood and cultivation, — 

 fertile plains, and steep and broken banks, and the Seine winding 

 among them and giving life and spirit to the whole. 



On the 19th I went in an omnibus to Damethal, a manufacturing 

 town about a league from Rouen. These omnibuses, or gondoles as 

 they are here called, run every half hour. Two valleys unite at the 

 lower part of the town ; I took that to the right, and then ascended 

 the hills on the left, where, on some rough uncultivated ground below 

 the woods, I had on a former occasion, in company with my friend T. 

 Corbyn Janson, found abundance of Orchis odoratissima. It is a late 

 Orchis, closely resembling O. conopsea in its general appearance, and 

 this time I failed to identify it. Hereabouts, too, I think we found 

 Stachys alpina : Anemone Pulsatilla and Stachys recta are very abun- 

 dant. Tilia parvifolia, Pyrus torminalis and Mespilus germanica are 

 found in the woods, but the two latter seem rather shy of flowerino-. 

 Luzula Forsteri grows here, almost to the exclusion of L. pilosa ; Phy- 

 teuma spicatum and Convallaria majalis are in considerable abundance. 

 Passing through these woods, and a cultivated tract through which 

 runs the road to Gournay, I again entered the forests, and, in a hollow 

 found a large plot of intermixed Orchis fusca and O. militaris. When I 

 speak of O. militaris, I mean a plant with pale purplish-grey acumi- 

 nate sepals, like those of O. Simia, but with a broader lip, which is 

 always rough with little tufts of short purple hairs. I have sketched 

 (fig. 4, 5, 6, p. 789) some of the lips of the O. militaris here found, one 

 of which is very remarkable, as the two upper lobes, the arms of the 

 monkey, are entirely wanting. On the same bank grew Euphorbia 

 dulcis and Cineraria integrifolia, which here, drawn up in the woods 

 has an appearance very different from that which it assumes upon the 

 downs of Sussex. 



On the recommendation of M. Pouchet, Professor of Botany, I went 

 on Saturday to the hills rising from the Seine above Rouen. I did 

 not go far enough to reach the Rocks of St. Adrien, which are chalk
