OF THE MATTO GROSSO EXPEDITION, 1891-92. 479 
BROSIMOPSIS, Artocarpearum, e tribu Euartocarpearum, gen, nov. (Pl. XXXI.) 
Flores dioici, omnes globoso-capitati, capitulis basi bracteis perpaucis parvis instructis. 
Flores 3: Perianthium subscariosum, tubulosum, 4-partitum, segmentis æstivatione 
imbricatis. Stamina 4, declinata, basi ipsi perianthii segmentorum inserta; 
filamentis dein longiuscule exsertis, sstivatione rectis; anthere subeylindrice, 
Ovarii rudimentum 0. Flores 2: 2-4 circa «equatorem receptaculi dispositi, eorum 
perianthium receptaculo. Ovarium receptaculo inclusum basique ei adnatum, 
sursum in stylum e receptaculo exsertum desinens ; stigmata 2, elongata, crassius- 
cula, a basi divergentia, apice acutata ; ovulum ab apice loeuli pendulum, anatropum ; 
micropyle supera. Fructus globosus vel subgloboso-didymus, exocarpio (se. recep- 
taculo ampliato) carnoso, endocarpio tenuiter crustaceo exocarpio deorsum concretum. 
Semina solitaria vel bina (et tune fruetus subgloboso-didymus), a dorso compressa, 
ambitu late elliptica vel suborbieularia; funiculus latus; hilum conspicuum, circu- 
lare; testa membranacea; albumen 0; cotyledones carnosze, una alterà duplo 
major; radicula supera.—Arbor lactescens. Folia ampla, breviter petiolata, indivisa, 
penninervia, tenuiter coriacea ; stipule laterales, firme, diu persistentes. Florum 
receptaeula in axillis plerumque solitaria, erecta vel patula, breviter peduneulata. 
Bractez exiguee, ovatee, receptaculo multoties breviores. Bracteolæ parve, peltatee, 
receptaculum femineum obtegentes et floribus masculis intermixtee. Flores masculi 
receptaculo hemisphzerico basi brevissime immersi. 
Genus singulare ob naturam fructus Brosimum in mentem revocat, ab eo equidem 
longe abhorret de receptaculo unisexuali, et floribus masculis toto colo disparibus, et 
floribus femineis zequatorialibus, nec apicalibus vel subapicalibus. Ab omnibus generibus 
reliquis. Brosimearum—scilicet Lanessania, Baill., Bosquiea, Thou., Scyphosyce, Baill. 
—(iffert, prseter alia, receptaculis unisexualibus, et ab Olmedieis receptaculis haud basi 
bracteis amplis -serialibus cinctis. Inter .Ewartocarpeas, Helianthostyli, Baill., e 
regione Amazonicá, videtur proxima, cujus flores masculi attamen rudimento, feminei 
apice stylo elongato instructo gaudent, et flores feminei solitarii. Cudrania, Tréc., genus 
gerontogzeum, floribus masculis aliquanto similibus, tamen flores femineos omnino 
dispares ostendit, qui etiam longe diversi in Treculiá, Decne., ex Afr. Trop. Itaque flores 
masculi Parartocarpi, Baill., stirpis Borneensis, perianthio carent et flores feminei 
perianthium contra praebent. Receptacula feminea Batocarpi, Karst., hucusque sola 
cognita, floribus dense aggregatis, perianthio instructis, necnon bracteis intermixtis obte- 
guntur. Moreis ab omnibus differt primo obtutu filamentis in alabastro rectis. 
(sp. nov.). Arbor elata ( 9 ) vel arbuscula ( 3 ) foliosa, ramulis 
subteretibus minute pubescentibus, dein glabris, cinereis irregulariter rimosis, crebro 
lenticelliferis, cicatriculis elliptieis eminentibus foliorum evanidorum abundanter 
instructis, vulgo 0:2-0:4 cm. diam. Stipuke erectee, circa 0*6 em. long., lanceolatee, 
acuminate, dorso puberul:e, membranace:e, longitrorsum  nervosee, decolores. 
Foliorum lamina oblonga vel oblon go-lanceolata, plerumque breviter cuspidata, 
basi leviter obliqua, obtusa, szepe leviter rotundata, margine revoluta, obsolete 
undulata, minute pubescens, cito glabra, usque 17:0 cm. long. et 7:0 cm. lat.
