the flower clusters, and here the descriptions show these to be | 
entirely distinct (see legend to fig. 4). 
Turning to the descriptions and plates left by other botanists 
of the immediately succeeding decades we find in JACQUIN Selec- 
tarum stir pinum Americanarum historia (1763) a plant described as 
D. lignosus: Citations to the D. lignhosus of Linn. Sp. Pl. 726 and 
Linn. Hort. Cliff. 360. t. 20 are given with question marks, indicat- 
ing that the author doubted that the plant he described was the 
same as that described by LinnaEus. An examination of his 
description makes it clear that the two plants were entirely differ- 
ent, for the plant of Jacquin had pilose stems and pods, peduncles 
shotter than the scabrous leaves, white flowers, and pods 3-4 
inches long, containing about 18 seeds, whereas, as we shall see, 
the plant described by LinnaEus had nearly smooth stems, pods, 
and leaves, peduncles longer than the leaves, purple flowers, pods 
1-2 inches long with 7 or 8 seeds at the most. 
Arron (Hort. Kew. 3:31, 33. 1789) recognizes both D. Lablab L. 
and D. lignosus L. and gives practically the same descriptions as 
are given by Linnarus. He states that D. lignosus was introduced 
into England in 1776 by Monr. THOUIN. 
In 1792 Situ (Spicilegium Bot. no. 2, Gleanings of Botany, 
pp. 19 and pl. 21) describes and pictures a plant which he calls 
D. lignosus. Smrru’s plate is here reproduced in fig. 5 and his 
description is so clear and concise that it is quoted in full as follows:
