lanceolatis subrhombeis acuminatis utrinque pilis appressis supra raris pubescentibus, bracteis basi 
latis Jonge acuminatis ante anthesin comosis, calycis laciniis lanceolatis acuminatis, leguminis 
articulis 5-8 hirsuto-scabris.—Columbia. 
Species D. Limensi valde affinis, at planta subscandens videtur, foliola majore (2-4-pollicaria), stipule et 
bracteee multo majores, longius acuminatee, et pili caulis ut in D. uncinato hamato-prehensiles nec ut in 
D. Limensi molles.

racemis paniculatis, floribus minutis, calycis laciniis setaceo-acuminatis suprema bifida, legumine

173. Desmoprum (Nephromeria) Barclayi, sp. n., caule flexuoso hirtello, stipulis brevibus latis 
deciduis, foliolis ovato-rhombeis acutiusculis utrinque preesertim subtus puberulis, racemis panicu- 
latis, leguminis stipitati demum glabri articulis 1-2 orbiculato-reniformibus submembranaceis glabris, 
margine seminali intrusa, isthmis angustissimis.—Central America. 
Species, ex diagnosi brevissima Candollei, D. infracto affinis, sed hujus leguminis articuli semi-orbiculati 
discrepant. Specimina nonnisi fructifera adsunt. Ramuli crassiusculi, virides, obtuse angulati, Stipule 
desunt nisi in gemmulis ubi breves sunt, latee, brevissime acuminate, striate. Stipelle parvee, lanceolate, 
acutissime. Petioli 2-3-pollicares. Foliola 2-3-pollicaria, lateralia minora, breviter petiolulata. Racemi in 
axillis superioribus et ad apices ramorum paniculam formant laxam divaricatam basi foliosam. Pedicelli 2 lin. 
longi. Bractez et flores desunt. Leguminis stipes 2 lin. longus, articuli 6 lin. longi et lati consistentia 
subchartacea, reticulati ; sutura dorsalis tres partes circumferentiee occupat, seminalis sinu acutangulo profunde 
intrusa. Semen parvum, ovato-reniforme. 
Although the old Linnean Hedysara have been broken up by modern botanists 
into several distinct genera, yet some of these, and especially Desmodium, have 
become so very numerous in species as to require further division into sections. 
De Candolle had distributed them provisionally according to their native coun- 
tries, but that is of less convenience in this instance than in many others, as — 
(owing probably to the prehensile nature of the hairs of the pods) the commoner 
tropical Desmodia are so wide spread that it is often difficult to say what is pro- 
perly their native station. I have attempted to establish sections on the forms of 
their fruit, which, though in some degree artificial, are the best I have been able to 
devise. Those above mentioned may be thus characterized. . 
Scorpiurus. Legumen angustum, elongatum, maturum yvix compressum, equilatum vel ad articulos
