(BOURGEAU 2005. 



long by 7 cm broad al the middle, ovate-lanceolate, acuminate, somewhat narrowed 

 downwards, herbaceous, dark-green. Rachis slender, short-hairy. Pinnæ 7 — 8 to a 



side, sessile, suddenly narrowed into a short, entire 

 apex, 3' i cm long, 1' -' cm broad, the lowest pair 

 generally somewhat shortened and reflexed; costæ 

 on both sides sparsely pubescent by a few longer 

 and more numerous very short hairs, surfaces other- 

 wise glabrous. Segments 9 — 10-jugate, oblong obli- 

 que, connected by a wing IV4 mm broad, the sin- 

 uses between acute, entire or slightly répand, the 

 basal ones of lower pinnæ shortened, of upper ones 

 equal or a little prolongated. Veins 5 — 6 to a side, simple, oblique. Sori a little 

 below the middle of the vein, exindusiale. Sporangia glabrous. 



A very distinct species not easily to be confounded with others. It is not 

 probable that Fournier had seen an authentical specimen of Ph. blancia, since he 

 described his Ph. caespitosa as new; the two are exactly the same species. Fée 

 described the rhizome as "rampant", but on the label to the specimen at Kew is 

 written : "rhizome decumb. terminal fronds". 

 Specimens seen: 



Mexico: Vera Cruz, Jared G. Sehmitli nr. 63 (Wi; Cordova, Bourgeau nr. 200,') (H, W, Mus. Paris. Ph. 



caespitosa Fourn.), H. Fink nr. 96a (W). 

 Guatemala: vicinity of Cacao, Barber nr. 171 (W, pinnæ acuminate). Alta Verapaz, near the Finca 



Sepacuite, Cook and Griggs nr. 57 (Wl 

 Costa Rica: Wercklé nr. 130 (C) — Grenadilla, Finca Hermes, Brade nr. 412 (R).

Syn. Aspidiuin tablanum Christ, Bull. l'Herb. Boiss. II. 5:

Type from Mexico: Chiapas, San Pablo, tierra tempiada 

 "auf Lehmboden", leg. Munch nr. 146 (C!). — The Costa Rican 

 specimen mentioned by Christ belongs lo Ü. bhmda. 



Very like ü. Manda, but larger: stipe 20 cm long, lamina 

 25 X 12 cm, slightly ciliate and costæ above strigose, otherwise 

 entirely glabrous. Pinnæ opposite, linear, shortly acuminate, 

 6— 6'/ä cm long, 12 — 13 mm broad, the lower ones reflexed and 

 not shortened, but below them I find in a single leaf a pair 

 of small auricles. Segments very obtuse, almost with a trun- 

 cate ape.K that is crenato-dentate. Veins 4 — 5-jugate, not very 

 oblique. Sori supramedial with a distinct, glabrous indusium. 

 Sporangia glabrous. — Rhizome erecl, 1 cm thick, 8 cm high, 

 scaleless.
