sometimes nearly as thick as broad, conseqaently the sori at 

 length not confluent.— Examp. : Bull. Dép. Agr. L N., 1908, XXI,

Vittaria (genuina), J.Sm.^ Mém. Acad. Tur., V, 413(J. Sm., 

 Journ. of Bot., IV, 67) differs from Scleroglossum in having the 

 sori immersed in relatively shallow marginal or submarginal grooves 

 with the lips as broad, or the outer lip produced only a little 

 beyond the inner, the inner lip not consisting of thickened costal 

 parenchyma, consequently the fronds not especially thickened 

 in the fertile région, and the sporangia intermixed with para- 

 physes. — Examp.: V. elongata, Sw., Bau. & Hook., Gen. Fil., 

 tab. LXVIII B] Bedd., Perns South. Ind., tab. XXI;- this Bull, 

 tab. V, fig. 5. 



Taeniopsis (Vittaria §), J. Sm. (l.c, 67) differs from Vittaria 

 (genuina) in having the sori submarginal or intramarginal, when 

 young protected by the recurved margin of the frond or by 2 

 latéral outgrowths of leaf tissue (lips) with the inner lip con- 

 spicuously narrower than the outer one or even obsolète and 

 the outer often rolled over the sorus when young, or, the outer 

 lip is ca as broad as (or narrower than) the inner one but then 

 distinctly diff'erentiated from the margin of the frond.— Examp.:

Monogramma (genuina) Schk., Krypt. Gew^, I, 82 (J. Sm., 

 1. c, 45) has the sori linear, single or double, parallel and close 

 to the Costa, if double then ultimately confluent, at length forming 

 a single continuons or interrupted sorus covering and hiding 

 the Costa, superficial or immersed, whether or not protected by 

 1 — 2 latéral outgrowths not consisting of thickened and widened 

 costal parenchyma; latéral veins wanting. — Examp. : M. furcata,
