Bell 4797 (holotype, CAL!, Acc No. 8312).	en	Das, Piu, Padhye, P. M., Mazumdar, Jaideep (2019): A new fern species Pteris subiriana (Pteridaceae) from India. Phytotaxa 391 (4): 247-252, DOI: 10.11646/phytotaxa.391.4.1, URL: http://dx.doi.org/10.11646/phytotaxa.391.4.1
0380C463E62EFFC8959BD9BF588AF9CB.taxon	diagnosis	Diagnosis: — Pteris subiriana (Fig. 1 A – H, 3 A – B) is similar to P. blumeana (Fig. 2 A – E, 3 C – D) in gross morphology and growth habit, but the former has a sub-erect rhizome (Fig. 1 E), bicolorous rhizome scales (Fig. 1 D, D 1, D 2) and distinct arcuate foldor band near to the leasurae in proximal surface of the spores (Fig. 3 A). In contrast P. blumeana has erect rhizome (Fig. 2 A), concolorous rhizome scales (Fig. 2 C, C 1, C 2) and tuberculate to fused verrucate ornamentation in proximal surface of the spores (Fig. 3 C, D). The stipe is glossy in P. subiriana, but matt in P. blumeana.	en	Das, Piu, Padhye, P. M., Mazumdar, Jaideep (2019): A new fern species Pteris subiriana (Pteridaceae) from India.

0380C463E62EFFC8959BD9BF588AF9CB.taxon	description	Description: — Plants terrestrial (Fig. 1 A), 61 – 104 cm tall. Rhizomes short, sub-erect, 2 – 3 cm long, 0.5 – 1.5 cm in diameter (Fig. 1 E). Stipe as long as the lamina, stout, scaly at the base, smooth, grooved above, 35 – 60 cm long, 0.4 – 0.6 cm in diameter, stramineous; rhizome scales same as stipe-scales, narrowly lanceolate, bicolorous, base cordate, margin ciliate, the central part composed of thick walled dark brown cells, margin pale brown. Laminae 32 – 40 long, 18 – 23 cm wide, bipinnatifid throughout except basally, imparipinnate apically, lowest pinnae pinnate-bipinnatifid with one or sometimes two developed basiscopic basal pinnules; pinnae 5 – 12 pairs, alternate to opposite, 9 – 16 cm long, 1.5 – 3 cm wide, sessile, basal pairs shortly stalked, lanceolate, acuminate (Fig. 1 A); costae bearing a short adaxial spine at the base of each segment midrib, spine more than 1 mm (Fig. 1 B); pinna-lobes (ultimate lobes) 20 – 30 pairs, 1.1 – 1.5 cm long, 2 – 3 mm wide, oblong to linear, narrower, apices rounded, entire, widely joined at their bases, base of sinus reaching to about 2 mm from the costa, without a sinus-tooth, lowest pair of veinlets between pinna-lobes and beneath the sinus free and curving evenly up to just above the base of the sinus, 8 – 14 pairs of veinlets above (Fig. 1 C). White or pinkish setae above the adaxial surface of the midribs, setae narrow, 1 mm long, triangular to lanceolate, pointed (Fig. 1 B). Sori sub-marginal, elongated, extending nearly towards the sinus and not reaching of the pinna-lobe; pseudoindusium hyaline, 87.5 × 12.5 μm, slightly elongated to irregular in shape (Fig. 1 F, G); sporangial stalk very long, biseriate; capsule globose, 550 μm long, 200 μm wide; annulus 18 - celled (Fig. 1 H); paraphyses pale, long, septate, 200 μm long, 10 μm wide. Spores golden brown in colour, trilete, triangular in polar view, margin continuous, corner rounded, size 40 – 42 μm, on proximal surface distinct arcuate fold or band present near to the leasurae and outside leasurae slightly tuberculate (Fig. 3 A), distal surface rugate, formed inside deltoid base, and smooth, apparently perispore is thick and single-layered (Fig. 3 B).	en	Das, Piu, Padhye, P.
