OROBUS. 



into -. 1. no more than nature, to be expelled by any amount 



Ordbus, a beautiful family, leaking into Lathyrus, but almost all 

 of the highest value in the rock-garden. Lathyrus now tending to 

 possess th< ramping trailers., while the neater-habited stay-at-home 

 plants sit quiet under the shadow of Orobus. All can be raised as easily 

 from seed as all peas, and the clumps divided in spring or autumn — 

 all the species blooming in spring and early summer. 



O. alius. See 0. pamionicus, Jacq. 



0. alpe-stris has one-sided flower-spikes, and may be seen on Rilo. 



0. ar menus stands about a foot high, and has purple flowers. 



0. aurantiacus has much the same habit, but the flowers are 

 of orange-yellow, a little tawny in their tone. It is hardly, if at 

 all, to be separated from 0. luteus. unless in the deeper tone of its 

 blossoms. 



0. aureus (0. luteus. Sibth.) differs from 0. luteus of the Eastern 

 Alps in having broader leaflets, which are not glaucous underneath, 

 while the stems and pedicels are hairy. Otherwise it is the same 

 .y plant that you see as you mount from Cortina to the Falzarego, 

 in the meadow and coppice, amply suited for some such spacious corner 

 at home, which it will occupy with its two-foot growth, with generous 

 loose spikes of large pale-golden Pea-flowers in summer. 



0. canescens (0. filiformis, Lam.) is a common sight in Southern 

 Europe, belying its name by being glabrous, and standing 18 inches 

 tall, with beautiful blue-and-white blossoms, four or nine to a head. 

 There is also a leafier form, 0. variabilis, from Eastern Cilicia, with 

 still larger flowers of rich blue-violet. Both plants are of extreme 

 beauty, and run freely in any light soil in a sunny place. 



0. cyaneus {Lathyrus) comes from Siberia and the stony places of 

 Alpine Anatolia. Caucasus, &e., and is a dwarf treasure of the best, 

 emerging quite early in the year with crumpled leaflets of bright glossy 

 green, from which soon appear handsome sprays or heads of large 

 blooms in the richest and clearest sapphire-turquoise blue. This 

 needs no more trouble than the ugliest weed, but. like many an 

 Orobus, is designed by nature for rather cooler places on the fringe 

 of brushwood. In all catalogues this is Lathyrus cyaneus. 



0. Fischeri has unbranching stems of about a foot, sparingly 

 furnished, with very narrow and pointed leaflets, only one pair going 

 to a leaf. The flowers are purple, and crowded into one-sided racemes 

 in early summer. (Siberia.) 



is the finest of all the yellow-flowered species. It
