150 GYMNOGRAMJlJE, § DICTYOGRAMME. 



§3. Stegnogramme. — Veins pinnated from the costule, connivenf, the lower 

 ones at least, in opposite pairs {as in Eunephrodium among Aspidieae). — Gen. 

 Stegnogramme, Bl. Hook. Gen. Fit. t. CXX. B. {from Presl.) 



50. G. (Stegnogramme) aspidioides. Hook, (not Klfs.) ; 

 caudex ascending more or less paleaceous-subrepent, whole 

 plant on both sides especially on the veins hairy (except the 

 caudex) sometimes densely villous, stipites terminal on the 

 caudex tufted a span to a foot long at length glabrous glossy, 

 fronds 1-1 i foot long 5-6 inches wide ovato-lanceolate acu- 

 minate pinnated pinnatifid at the apex firm-membranaceous, 

 pinnae opposite or alternate sessile subtruncate and more or 

 less adnate at the base .3-4 inches long rarely an inch wdde 

 oblongo-lanceolate lobato-pinnatifid, superior ones confluent, 

 veins 5-6 pairs from each costule simple 3 lower ones united 

 to those opposite and forming an excurrent spurious vein 

 reaching to the sinus, those in the lobes free all soriferous, 

 sori linear-oblong occupying nearly the whole length of the 

 veins.— Hook. Gen. Fil. t. 120. B., and Ic. PL x. /. 950 {or 

 Cent, of Ferns, t. 50). G. Stegnogramme, Bl. Fil.Jav. p. 98.

Hab. Banks of rivers, Java, alt. 3-4000 feet, Blume, Thos. Lobb, De Vriese and 

 Teijsmann, n. 612. Eastern Bengal, Khasya, alt. 6000 feet, Griffith, Hooker fil. 

 and Thomson. Ceylon, Gardner, n. 1292. — The Java specimens are generally the 

 largest and most copiously villous. Stegnogramme Sandvicensis, Brack., is Poly- 

 podium (Goniopteris) Sandvicense of this work. 



§ 4. DiCTYOGRAMME. — Veins uniting so as to form costular irregular areoles, 

 ultimate veinlets near the margin, free. — Gen. Dictyogramme, Fee. 



51. G. (Dictyogramme) amhigua. Hook. ; caudex ?, stipes ?, 

 fronds H foot and more long 6-12 inches wide sparsely pi- 

 lose on both sides with long brown jointed hairs membrana- 

 ceous ovate or ovato-lanceolate acuminated pinnated pinnati- 

 fid at the extremity, pinnae sessile or nearly so distant in 

 subopposite pairs 4-6 inches long ^ an inch (in some oi the fer- 

 tile pinnae to l-H i"ch long) in the sterile ones oblongo-lan- 

 ceolate pinnatifid rather more than halfway down to the costa, 

 segments oblong subfalcate obtuse entire, veins anastomosing 

 so far as to forn) a series of costal areoles and 2 or 3 costular 

 ones nearly all the rest free simple or forked soriferous, sori 

 oblong subpulvinate simple on the simple veins forked on 

 the forked veins rarely suborbicular. — Digrammaria ambigua.
