on which Ingie stands is sandy at the base and clayey at top ; the 

 stratum of clay contains, in other places, beds of a soft calcareous 

 stone. Orchis hircina here grows upon the sand, being less particular, 

 in a warmer climate, in its choice of soil than it is with us or in Nor- 

 mandy. Thlaspi perfoliatum, Holosteum umbellatum and Bromus 

 tectorum are no longer confined to walls and dry banks, but descend 

 into the cultivated land. The other plants were : — 



Cavuui BHlbocastaninii Fumaria pavviflora Hypochasris maculata 



Bupleurum rotimdifoliuin Campanula Speculum Artemisia campestris 



Neslia pauiculata Diautlius prolifer Oruithogalum umbellatuui 



Erysimum orieutale Silene conica Veronica triphyllos 



On the 30th I called by appointment, at 7 o'clock, on M. Jullien, 

 and we set off, accompanied by the premier gargon of the botanic 

 garden and a lad with him, to St. Cyr en Yal. We did not reach the 

 village till near 12, although only about six miles from Orleans ; but 

 my companions were not well acquainted with the grasses and Cari- 

 ces, and found fully as much to do as myself. Beyond St. Cyr is a 

 little valley, if so slight a depression may deserve the name, at first 

 presenting barren banks and pieees of woodland, and becoming after- 

 wards boggy ; and we passed over heaths and through w^oods on our 

 return, the country being everywhere nearly flat. Our plants were: — 



Madia sativa, the relic of Scutellaria liastata Vicia lutea 



cultivation Anarrliinum bellidifolium Trifolium ochroleucum 



Cliondrillajuncea Linaria Pelisseriana Vicia latliyroides 



Hieracium Auricula Piuguicula lusitanica Liipinus tenuifolius 



Litliospermum arvense, flo. Veronica acinifolia Latliyrus augulatus 



Stacliys germanica [roseo Scleranthus perennis Aristolocliia Clematitis 



Brassica Cbeirautlius Lobelia urens Orcbis laxiflora 



Turritis olabra Astrocarpus sesamoides Carex ericetorum 



Herniaria birsuta Heliantbemum umbellatum C. Scbreberi 



Before returning to Orleans we visited the source of the Loiret ; it 

 is a nearly circular basin at the foot of a woody bank, in which the 

 spring boils up with considerable force, and forms at once a river, 

 which, after a quiet course of a few miles, joins the Loire. It is a 

 charming spot, well shaded ^ntli fine trees, and breathing sweetness 

 and repose. In this walk (which exceeded twenty miles) the want of 

 ferns in situations apparently very favourable to them, was very strik- 

 ing. Wo saw only two or three of the most common species, and not 

 many plants of those. This, I apprehend, is tlie most eastern habitat 

 known for Piuguicula lusitanica.
