PURPLE MEDICK OR LUCERNE. 72 



Purple Medick or Lucerne (Medicago sativa.) Plate 73. 



Though the rambler will find this handsome plant growing 

 apparently wild in the hedgerow and on the borders of fields, 

 he must not too hastily conclude it is a native. The species 

 has been largely grown here as a green fodder plant, for 

 which it is highly esteemed, and it has escaped from the fields 

 and reproduced itself without man's aid. A glance at its 

 flowers will show it is a leguminous plant. Its stems are hollow, 

 branched ; its leaves trifoliate, with long-pointed stipules at 

 the base of the leaf-stalk. From the axils of the leaves arise 

 long stalks, whose free ends are crowded with the deep purple 

 (sometimes yellow) flowers. A peculiarity of this genus^ consists 

 in the seed pod being more or less spirally twisted. In the 

 present species it is downy and has two or three coils. It 

 flowers from May to July. 



It has been thought to be a cultivated variety of the next 

 species, M.falcata. The name Medicago is from the old Greek 

 medike^ so-called because it was introduced into Greece by the 

 Medes. The following species also occur in this country : 



I. Yellow Sickle Medick (M. falcata), with yellow (sometimes violet) flowers, 

 and a flat downy pod coiled in the shape of a sickle or a ring. Dry gravelly banks, 

 old walls and sandy wastes in the Eastern Counties. June and July. This and 

 M. sativa are perennials ; the following are annuals : 



II. Black Medick or Nonsuch (M. lupulina). So much like Trifolium pro- 

 cnmbens, described on p. 49, that farmers have given it the name of Hop-Trefoil, 

 which properly belongs to the latter species, from which this may be easily separated 

 by noting that the black kidney-shaped pods are naked, that is, not wrapped in the 

 dried flower. It should also be observed that the pods are marked by prominent 

 veins running throughout their length. Flowers small, crowded, yellow. Waste 

 grounds and cultivated fields. May to August. 



III. Reticulated Medick {M. denticulate?). Stems creeping. Leaflets heart- 

 shaped, toothed. Flowers yellow, in umbels. Pod beautifully covered with network 

 of veins ; broad, flat, and coiled into a spiral ; edges with double row of spines. 

 South and Eastern Counties, and Ireland. May to August. 



IV. Spotted Medick (M. macitlata). Similar to last, but pod more globose, net- 

 work faint, the spines long and curved. Leaflets often with black spot in centre. 

 Leaf-stalk hairy. Gravelly pastures and hedgebanks in England and South 

 Ireland. May to August.
