NATURAL ORDER LEGUMINOS2. 
Sub-order—PaPILIONACES. Tribe—Lotesz, 
Puate VIII.—Lupinus reticulatus. Deso. Grenier and Godron. 
Not given by Woods. 
Geveric.—Style subulate, ascending, having the stigma slightly bent 
forward. Pod large, oblong, divided in the interior by partitions form- 
ing shallow cavities containing the seeds. Seeds having the funicle 
narrow at the hilum. Stamens monadelphous. Calyx deeply divided 
‘into two separate lips. Leaves digitate, having stipules united to the 
petiole. 
Speciric.—Pod wavy on the upper edge. Seeds 5 to 7, speckled with 
grey, and marked with black and white streaks. Calya furnished on 
either side with a small linear. appendage; upper-lip short, bifid. 
Flowers alternate, bright purplish blue. Leaves linear-obtuse, chan- 
nelled. 
ExpLANATION OF PiaTE VIII.—This plate represents Lupinus reticu- 
latus, a plant about which there has formerly been some confusion. Fig. 
1, half of a nearly ripe pod of the natural size, showing the partitions, 
with seeds in them. Fig. 2, Calyx, with the ovary removed, showing 
the linear appendage. Fig. 3, the lanceolate, deciduous bract, which 
falls as soon as the flower begins to open. 
Remarks.—There is no other Lupine known as growing at Mentone, 
but I believe that the present species may be distinguished from any 
other by its narrow channelled leaflets. Papilionaceous plants are gene- 
rally considered as a sub-order of that great Leguminous Order, which is, 
after the Synantheraceze or Composite plants, the largest in the world. 
Among the productions of the present sub-order are the indigo of com- 
merce (Indigofera tinctorea and cerulea), liquorice (Glycyrrhiza glabra), 
peas, beans, clover, &c. ; also, many showy garden plants, as Laburnum, 
Wistaria, Robinia, &c. The two other sub-orders are the Czesalpinex and 
Mimose. The former contains the Cassia, which yields the senna of 
the drug-shops, and the Carob-tree (Ceratonia siliqua) to be seen com- 
monly at Mentone; the latter, Acacias, species of which (A. vera and 
arabica) yield gum-arabic, and the genus Mimosa, from which the 
sub-order is named. The specimen figured was brought to me on April 
7th, when the flowering was commencing ; the pods were gathered in 
May.
