MR. G. BENTHAM’S SYNOPSIS OF DALBERGIES, 
$ 2. OBLONGA. 
13. M. GRACILE (Benth. in Ann. Mus. Vind. ii. p. 98, et in Mart. Fl. 
Bras. Leg. ined.), stipulis demum indurato-spinescentibus, foliolis 
35-51 parvis oblongis obtusis mucronulatis, venulis arcuato-anastomo- 
santibus, racemis axillaribus pedicellisque subfiliformibus, staminibus 
monadelphis.—Foliola 3-5 lin. longa. Racemi plerique simplices et 
solitarii. Pedicelli 14-2 lin. longi. Flores vix 4 lin. 
Hab. Brazil, Schott. 
A very distinct species in its slender inflorescence and small leaflets, 
which give it something of the look of an /Eschynomene. The pod is un- 
known, but the flowers are quite those of Macherium. | 
14. M. NicTITANS (Benth. in Ann. Mus. Vind. ii. p. 98, et in Mart. Fl. 
Bras. Leg. ined.), stipulis induratis longis validis rectis spinescen- 
tibus, foliolis 11-15 parvis oblongis obtusis rigidulis subtus pubes- 
centibus venulis arcuato-anastomosantibus, racemis leguminibusque 
rufo-pubescentibus.— Nissolia nictitans, Vell. Fl. Flum. vii. t. /5.— 
Foliola iis M. sclerozyli simillima, 10-14 lin. longa, circa 4 lin. lata. 
Hab. Brazil, Pohl. 
Only seen in fruit, and figured also in fruit by Velloso, but distin- 
guished from all others by the straight spines, which are often above an 
inch long. 
15. M. scLEROxYLON (Tul. in Arch. Mus. Par. iv. р. 93), stipulis 
deciduis inerme, foliolis 11-17 parvis oblongis retusis subtus pube- 
rulis, venulis arcuato-anastomosantibus, racemis puberulis, legumine 
glabro.—Foliola 6-10 lin. longa, 3-4 lin. lata, fere M. nictitantis. 
Legumen ad semen non intrusum. 
Hab. Brazil, prov. Minas Geraes. 
This also has only been seen in fruit. It is very near the last, but 
has no spines, and the pod is straighter and glabrous. It appears also 
allied to the Drepanocarpus floridus, which, having as yet been only seen 
in flower, may prove to be a Macherium. 
16. M. sorpipum (Benth. in Mart. Fl. Bras. Leg. ined.), inerme, 
foliolis 21-31 parvis anguste oblongis obtusis subtus pubescentibus 
venulis tenuissimis reticulatis, racemis fasciculatis rufo-pubescentibus, 
vexillo glabro, staminibus monadelphis.—Foliola 8-10 lin. longa, 3 
lin. lata, вере mucronulata. Flores fere 3 lin. longi. Ale parum 
arcuatz. 
Hab. Brazil, prov. Minas Geraes (Claussen, n. 139). 
The specimens which I have seen are not good, but do not sufficiently 
agree with those of the M. sclerozylon to be considered as the flowering 
state of that species, although evidently allied to it. 
17. M. MOoRITZIANUM, sp. n., inerme?, foliolis 19-25 oblongis obtu- 
sissimis retusisve venulis tenuissimis reticulato-subparallelis glabris 
v. minute puberulis, racemis paniculatis rufo-tomentosis, vexillo 
glabro, carina valde arcuata, staminibus isadelphis, legumine tomen-
