 sufferrugineo-pubescentia; stipulae parvae, su- 

 bulatae. 



aa. Capsulae pars seminifera ellipsoideo-globosa; 

 arillus semen aequans; rami teretiusculi; 

 foliola supra sublaevigata, intus fibris crebris 



instructa 59. P. ferruginea. 



ßß. Capsulae pars seminifera fusiformis; arillus 

 quam semen dimidio brevior; rami costati; 

 foliola supra quoque reticulata, intus fibris 

 raris instructa, epidermide inferiore crystal- 

 lophora 60. P. fusiformis. 



Sect. IV. Pachytoechus Radlk. 11. cc. — Capsula exalata, ovata vel subglobosa, longe 

 stipitata, glabra vel tomento brevissimo adpresso induta, mesocarpio parenchy- 

 matico crasso paucinervi, endocarpio sat crasso sed minus tenaci, Capsula sicca inde 

 plerumque crassius crustacea (unde sectionis nomen), attamen sat fragilis, reticulato- 

 venosa, longitudinaliter leviuscule 6-costata (in 2 speciebus — P. linearis et platy- 

 misca — ignota); semina ovoidea vel e trigono depresse globosa vel hemisphaerica, 

 fere tota arillosa, arilli marginibus dorso valde approximatis (P. pterophylla, mar- 

 ginata, grandifolia, ingaefolia, pachycarpa, xestophylla, venosa) vel supra testae 

 areolam et ipsam strato arilloso tenui obtectam plicatim conniventibus et contiguis 

 (P. carpopodea); embryo oleosus vel oleoso-farinosus, cotyledonibus crassis, parum 

 curvatis, superpositis (cf. Fig. 5); flores sat robusti, sepalis subcoriaceis, 3. et 5. 

 usque ad medium vel altius (in P. pterophylla interdum — forsan in P. xestophylla 

 quoque — basi tantum) connatis; thyrsi solitarii vel paniculatim congesti; corpus 

 lignosum simplex; folia imparipinnata, raro bijuga (P. olivacea, platymisca, xesto- 

 phylla, venosa), plerumque 3-(4-) juga, tumque jugo infimo plerumque (excepta 

 P. pterophylla) utrinque ternato, rarissime depauperato (P. marginata, carpopodea), 

 petiolo rhachique saepius insigniter alatis, stipulis plerumque conspicuis; foliola 

 nunc (in sp. 61 — 65) glandulis malleoliformibus, nunc glandulis subscutatis immersis 

 tumque prope paginam superiorem fibris sclerenchymaticis instructa (sp. 66—71); 

 epidermis non mucigera. (Species plures brasilienses, 2 guianensi-brasilienses — 

 P. ingaefolia, venosa — , 2 peruvianae — P. olivacea, linearis — , 1 in Columbia et 

 Nicaragua indigena — P. pterophylla). 

 A. Foliola glandulis stipitatis malleoliformibus obsita, fibris 



sclerenchymaticis prope paginam superiorem nullis. 



a. Folia pinnatim composita. 



aa. Folia 3 — 4-juga, foliola serrato-dentata; Capsula 



tomentella (sp. columbiano-nicaraguensis) . . . . 61. P. pterophylla. 

 bb. Folia 2-juga, foliola remote obtuse dentata; Capsula 



(juvenilis) glabra (sp. peruviana). ....... 62. P. olivacea.
