lower half, usually not more than a line long, comphcate, digitate, subacute, clothed Appendix I. 



with hairs similar to those of the branches, but shorter. Flowers copious, solitary, 



or rarely geminate on a thread-like, nearly naked, ascending peduncle 3-4 lines 

 long. Calyx | line deep, densely firmly pilose ; teeth deep, linear. Corolla red- 

 dish, three times as long as the calyx, externally pilose. Stamiual sheath ^ inch 

 long. Pod cylindrical, sessile, |-| inch long, at first obscurely hispid, finally gla- 

 brescent, dark-brown, straight, many-seeded, not at all torulose. 



I. dissitiflora; Bakei: Suffruticosa, ramulis gracillimis teretibus obscure pilosis, 

 stipuHs setaceis, fohis petiolatis pinnatis, foliolis 1-4-jugis lineari-subulatis oppo- 

 sitis pallide viridibus setis paucis adpressis, racemis laxe 3-5-floris pedunculatis, 

 calyce minuto dense griseo-hispido dentibus lanceolatis, petalis parvis purpureis, 

 ovario cylindrico raultiovulato. 



Belongs to section Bissitijlorce, next I. pentaphylla, Linn., which it closely resem- 

 bles in the flowers, but differs entirely in its leaflets and shrubby habit. 



Stem erect, suffruticose, with copious, very slender erecto - patent branches clothed 

 only with a few scattered, adpressed, bristly hairs. Stipules minute, setaceous, 

 persistent. Leaves of main stem an inch long, distinctly stalked, with 3-4 distant 

 pairs of opposite, linear - subulate leaflets, which are \ inch long, gray -green, 

 pointed, narrowed at the base, rather thick in texture, clothed only with a few 

 obscure adpressed hairs like those of the branches. Leaves of branches often 

 with only 3-5 leaflets. Eacemes about as long as the leaves, laxly 3-5-flowered, 

 distinctly stalked. Bracts minute, subulate. Pedicels nearly or quite as long as 

 the calyx. Calyx ^ a line deep, densely bristly ; teeth lanceolate, as long as the 

 broadly funnel-shaped tube. Corolla purplish, three times as long as the calyx, 

 shortly bristly. Ovary cylindrical, multiovulate. Ripe pod not seen. 



L Cameroxi, Baker. Fruticosa, ramulis gracillimis teretibus obscure pilosis, stipulis 

 minutis setaceis, foliis pinnatis breviter petiolatis foliolis 2-3-jugis oblongis sub- 

 coriaceis utrinque tenuiter pilosis, racemis densis brevibus conicis sessilibus folio 

 brevioribus, calyce, minuto oblique campanulato argenteo-sericeo dentibus deltoi- 

 deis, petalis angustis elongatis extus brunneo-sericeis, ovario cylindrico multiovu- 

 lato. 



Belongs to section Tmctoriw, next /. tondosa, Baker, from which it differs by its 

 pilose leaves and branchlets, argenteous calyx, etc. 



Habit quite shrubby. Branches slender, terete, thinly clothed with minute, adpressed, 

 white hairs. Stipules and stipellae setaceous. Leaves short-stalked, 1^2 inches 

 long ; leaflets 2-3-jugate, oblong, subcoriaceous, mucronate, i-f inch long, rounded 

 at the base to a short petiolule ; side ones opposite; both surfaces, especially the 

 lower, clothed with short, minute white hairs. Flowers in dense racemes, an inch 

 long, which are sessile in the axils of the leaves. Bracts lanceolate-navicular, 

 minute, argenteous, caducous. Pedicels very short. Calyx obliquely campanulate, 

 scarcely h a line deep, densely argenteo-sericeous ; teeth deltoid. Corolla ^ inch 

 long, densely brown-silky. Ovary cylindrical, multiovulate. Ripe pod not seen. 



Erioseiia rhynchosioides. Baker. Yolubilis, dense griseo-pubescens, stipulis parvis 

 lanceolatis persistentibus, foliis longe petiolatis ternato - pinnatifidis subcoriaceis 

 conspicue venulosis, foliolo terminali oblongo distincte petiolulato obtuso minute 

 mucronato, floribus 4-8 in racemum capitatum densum longe pedunculatum dispo- 

 sitis, pedicellis brevissimis, calyce campanulato dentibus magnis lanceolatis, petalis
