84 NEPHRODIUM, ^ LASTREA. 



§ Lastrea. — Vebis and veinlets free, not connected or conniuent, except in some 

 very rare or exceptional cases. Lastrea, Pr. and others. (See my remarks on 

 the limits of the genera of Aspidiaceae at p. 5 of this vohime, and p. 6, for my 

 views on Aspidium and Neplirodium.) 



* Fronds not compound ; that is, the divisions do not extend quite to the 

 racliis. Sp. 38, 39. 



38. N. (Lastrea) pedatum. Hook. ; caudex short thick sub- 

 horizontal paleaceous, stipites tufted 4-6 inches long rather 

 stout ebeneous^ fronds coriaceous 3-5 inches long cordate 

 pedato-trilobate or tripartite, lateral lobes dimidiato -cordate 

 with the lower margin only lobed, terminal one uniformly 

 pinnatifido-lol)atc, veins free or occasionally anastomosing, 

 sori scattered, involucres reniformi-cordate. — Aspidium, Desv.

Hab. West Indies: Jamaica, Wilson. Bancroft, etc. ; Cuba, Linden, n. \^^&, 

 Wright, n. 997. — A small plant with the habit of Euaspidium or Sagenia (and 

 hence Mettenius places in the same section with Aspid. cicutarium), but the 

 veins very rarely anastomose. 



39. N. ? (Lastrea?) Braunianum, Hook. ; '' frond membra- 

 naceous cordato-ovate acute deeply bipinnato-partite pilose 

 on the costa and veins, primary segments lanceolate acumi- 

 nate diminishing in size upwards, the lowest ones oblique, 

 all of them confluent with a broad wing, secondary segments 

 connected by acute sinuses, superior ones falcato-ovate en- 

 tire, lowermost ones oblong acute serrate, lowest ones of the 

 inferior side of the lowest segments elongated pinnatipar- 

 tite, tertiary veins generally forked soriferous at the apex of 

 a superior branch and generally abbreviated, sori in the mid- 

 dle Ijetween the costules and the margins of the segments, 

 involucre glanduloso-pilose horseshoe-shaped or auriculate." 

 Aspidium Braunianum, Kurst. Fil. CoJomb. p. 63. t. 31. 



Hab. On trees and stones in shady woods of the eastern Cordillera of Bojiota, 

 near Villavizenceo, Karsten. — This is quite unknown to me. The beautiful ligure 

 represents a frond rather n>ore than a foot long, with somewhat of the habit of 

 the Sagenia-^vow]) of Euaspidium, but with free veins, and, however deeply bipin- 

 natifid, it is still a simple (,not a compound) frond, all the segments being united 

 l)y a broad and acutely-lobed wing. The involucre (at least at f. 7, though not at 

 f. 6) represents that kind with a decurrent lobe, common in many species of 

 Athyrium, especially Ath. (or Asplenimn) Filix-fcemina. 



** Pinnate, pinna pinnatifd. Stipites jointed ahove or l/eloiv the middle. 

 Arthropteris, /. Sm. Sp. 40-42. 



40. N. (Lastrea) albo-punctatum, Desv. ; caudex very long
