from Linnseus's original illustration (9) considerably, and one may 
seriously doubt whether it is the same species. 
Two other illustrations of Dolichos Ugnosus. both colored, re- 
semble Linnseus's original much more closely, namely. Smith's (18) 
and Curtis's (4). Each of these illustrations depicts a plant with 
red flowers and with small leaflets, as in Linneeus's illustration (9). 
The plant of Smith shows the leaflets acuminate, not acute, as 
drawn by Linnseus and by Curtis. Smith says the mature pods are 
" an inch long, a little recurved, brownish, smooth.*' Xone of these 
three illustrations agrees with any of the 60 varieties of the bonavist 
grown at Arlington Farm, and they may well represent another 
species. Indeed, Smith's plant may be distinct from that of Cur- 
tis. The latter was considered a new species by Don (5) , who named 
it Dolichos curtisii. Smith's plant may perhaps be Dolichos jac- 
quinii DC. 
The opinions of many later botanists who did not have much 
first-hand knowledge on which to decide whether Ugnosus was 
really a different species from labial) may be disregarded. The 
opinions of botanists who studied the flora of India are, however, 
entitled to greater weight, inasmuch as both species are supposed to 
be from that region. 
Roxburgh (15) differentiates Dolichos labial) from D. Ugnosus 
as follows : 
Legumes horizontal, compressed, semilunar, with a straight 
scabrous back ending in a straight, daggered point labial). 
Legumes linear, oblong, slightly incurved, torulose, both 
margins turned and rugose, with a subulate, recurved 
apex Ugnosus. 
Of the former, Roxburgh cites seven varieties, with three of 
which he identifies plates 136, 137, and 141 of Rumphius (16). Of 
the latter, he lists six varieties, with one of which he regards plate 
25 in Kaempfer as identical. 
Plate 136 of Rumphius (16) has already been referred to. 
Plate 137 gives an oblique view of full-grown pods that apparently 
are oblong, but probably are broadest toward the apex, as in ordi- 
nary varieties of the bonavist. 
Plate 141 is clearly a species of Canavalia. 
Plate 25 of Kaempfer (7) has the immature pods falcate, while 
the mature ones are nearly straight and not broader toward the apex ; 
in other words, they are linear and not different in form from those 
on plate 136 of Rumphius (16), except that the tip is incurved. 
Judging from the plates cited, Roxburgh seems to have given great 
weight to the form of the tip of the pod, but this character is of 
little significance. In our opinion, plates 136 and 137 of Rumphius 
(16), as well as plate 25 of Kaempfer (7), all clearly represent the
