MICROPTERYGIUM. 385 
Pedicellus validus brevis. Capsula magna cylindraceo-oblonga, triplo 
fere longior quam lata. 
Amenta ¢ in planta propria, ramum posticum breviorem longioremve 
terminantia, circinnata, julacea ; braceteze ad 12-jugee, imbricate, 
subrotund, cymbiformi-complicatze (arte explicate paulo latiores 
quam long), acuminulate bidentuleve, subdenticulate, valde 
pellucidee. Bracteolee oblongo-rotundze bifidulee ubique obvie. 
Specimina subnom. “Micropterygium vulgare Nees,” acel. Montagne 
recepta, ad hancce speciem spectant. Folia e cellulis alte et subacute 
conicis asperrima, toto margine serrulata et celluloso-erosa. Foliola 
quadrato-rotunda, apice subtridentata, valde celluloso-serrulata, ramorum 
tenuiorum oblonga ovaliave, bifidula. Perianthia omnino eadem ac in 
nostra. 
In M. Campana aderat forma dense late czespitosa, ex albido-viridi 
tufula; foliis confertis laxe complicatis cymbiformi-concavis abrupte 
acutis, lamella inferiore latiore, ovato-lanceolata, ala breviore, cellulis 
supra subtusque in conum truncatum verruculosum alte prominulis.

3. MICROPTERYGIUM ANGUSTISTIPULUM, Spruce. 
Hab. ad saxa in M. Campana ceterisyue Andibus Peruvianis inferioribus, 
alt. circiter 1000™. 
F. lobus *6 x °33, lobulus 5 x °15, ala ‘5 x °125, ¢ <4, ; foliola °35 x 15mm, 
Ceespitosa pallide rufula. Caules vix pollicares, basi brevi repentes, dein 
assurgentes et arcuato-decurvi, vage vel laxepinnatim ramosi, ramique 
(seepius elongati) subzequifoliati, solum basi apiceque subparvifolii ; 
hic illic, basin versus preecipue, rarius e medio tergo apiceve, flagella 
pallida tenuia flexuosa centimetrum longa, primo visu aphylla sed 
radicellosa, proferentes. Alia flagella autem apice normaliter foliosa 
interdumque ramulosa. 
Folia pulchre disticha, eequitanti-subimbricata, arcte complicata ; lobus 
(s. lamina superior) duplo fere longior quam latus, oblique ovato- 
oblongus vel subrhomboideus, truncato-obtusatus, basi dilatatus 
subinde subsemicordatus, margine e cellularum tuberculis minutis- 
sime asperulo, superne angulato-repando rarius grosse subdenticulato ; 
lobulus (s. lamina inferior) dimidio lobo subangustior, eidem margine 
suo inferiore adnatus, haud tamen ad lobi ipsum marginem sed paulo 
intra (sicuti limbus alave lobulum superstet), paulo ante folii apicem 
sensim vel subabrupte desinens, margine superiore scaberulo repando ; 
ala semilunari-lineari-lanceolata, lobulo subaquilata. Cellule pree- 
minute, subguttulate, subquadratee rhombezve (medium folii versus 
distincte subhexagonze) parum prominule, tota superficie crebre 
minute tuberculose, unde folia asperula evadunt.—Folia flagellorum 
foliolaque minuta, subequimagna, distantia, squameformia, apice vel 
integra vel digitatim fissa ; radicellz (seepius 8), omnibus foliis adjectie, 
4-10-fasciculate, filiformes, pallide. 
Foliola dimidio folio sublongiora, concava, subappressa, vix imbricatula, 
ovato-ovalive-lanceolata, apice spinoso-bidentula vel 3-4-dentata, 
raro integra et acuminata. 
Flores dioici: 9 subbasales, ramulo brevi sistentes (imperfecti solum 
visi).
