without the flower, the genus cannot be ascertained, I have refrained from giving 
it a specific name. 
32. Puaca candidissima, sp. n., decumbens, tota pube adpressa subsericea candidissima, stipulis

semilineam longee, acut#. Calyx 2 lin. longus. Corolla glabra, (violacea?); vexillum calyce triplo longius ; 
ale paullo breviores, prope basin intus concavo-gibbe, carine equilongee leevissime adbeerentes, non plicatee. 
Stamen vexillare a basi liberum, ceetera alte connata. Antheree inter se consimiles, oblonge, versatiles, eglandu- 
lose. Legumen valde inflatum, 9 lin. longum, sutura seminali breviter intromissa. Semina plurima, orbiculari-

culatisve, pedunculis folio longioribus, spica oblonga laxa, bracteis parvis, calycis ovati dentibus late 
subulatis brevibus, ovario sessili villoso.—Bay of Magdalena, and San Quentin. 
Habitu preecedenti affinis, et pariter candidissima, sed pubes minus appressa. Stipule inferiores 3-4 lin. 
Jongee, acute, ad medium concrete, superiores multo minores. Folia demum 4-pollicaria. Foliola inferiora 
3-4 lin. longa, acutiuscula, superiora gradatim minora et latiora ; ultima fere orbicularia, obtusa, 1-14 lin. longa, 
omnia mollissima, basi rotundata, Flores fere P, candidissime sed in spica minus densi, et corolla ex sicco flava 
videtur. Legumen non vidi. 
34. Puasroius (Drepanospron) jfiliformis, sp. n., volubilis, glabra, ramis gracillimis, foliolis 
hastato-trilobis lobo medio productiore oblongo, vel rarius ovato-deltoideis subrhombeisve, pedun- 
culis folio longioribus supra medium interrupte paucifloris, bracteis bracteolisque minimis lanceo- 
latis, pedicellis calyce minimo vix duplo longioribus, calycis labio superiore truncato vix emarginato, 
dentibus lateralibus latis brevibus, infimo acuto tubo dimidio breviore, legumine pendulo falcato 
glabro.— Bay of Magdalena. 
Affinis P. leptostachyo. Annuns videtur, ramulis filiformibus. Stipule minute, oblonge, striate. Petioli 
1-1}-pollicares, tenues, Foliola seepius profunde triloba, lobis oblongis, intermedia 6-12 lin. longa, lateralibus 
dimidio brevioribus, interdum late subrhombeo-ovata, integra vel sinnato-triloba, 6-9 lin. longa, ramulorum 
sepe multo minora. Stipelle minute, oblonga, acutiuscule, striate. Pedunculi filiformes, 2-24-pollicares. 
Florum nodi pauci, distantes, 2-3 flori. Pedicelli floriferi lineam longi, fructiferi paullo longiores, recurvi. 
Bractewe minutissime, lanceolate. Calyx linea brevior, bracteolis dimidio brevioribus appressis. Corolla fere 
P. paniculati, sed multo minor. Vexillum late orbiculatum, basi intus biappendiculatum, medio leviter 
callosum. Ale vexillo paullo longiores, oblique oblonge, Carina apice anfractibus completis spiraliter torta, 
acuta. Stamen vexillare basi geniculatum, inappendiculatum. Ovarium puberulum. Stylus apice valde 
incrassatus, stigmate laterale. Legumen forma fere P. Jwnati sed quadruplo minus, vix enim semipollicem 
longum, lunatum, utrinque acutum, glaberrimum, Jeve, intus nudum, 6-8-spermum. Semina reniformia, 
subquadrata, leevia.
