20. LINDSAY A, EULINDSAYA. 105 



Hab. S. Camarines, Malay Archipelago ; gathered by Cuming. Much resembling 

 small unbranched forms of L. nitens, but recognizable by its simple venation. 



4. L. ovata, J. Sm. ; rhizome short-creeping ; st. 2-3 in. 1., wiry, flexuose, 

 black ; Jr. 4-6 in. 1., f in. br., simply pinnate ; pinnce 4 lin. 1., 2 lin. deep,^n6T 

 imbricated, the lower ones with their own breadth between them, horizontally 

 oblong, the point very blunt, the lower side obliquely truncate at the base, the 

 upper slightly auricled ; texture subcoriaceous ; sori in a continuous marginal 

 line. Hk. Sp. 1. -p. 205. t. 64. A. 



Hab. Same station as L. adiantoides ; gathered also by Cuming. 



5. L. concinna, J. Sm. ; rhizome short-creeping ; st. 2-4 in, 1., wiry, erect ; fr. 

 -12 in, 1., | in. br., simply pinnate ; pinnce 4 lin. 1., 2 lin. deep, very blunt on 

 the outer edge, the upper edge very slightly crenate, the upper ones close together, 

 but scarcely imbricated ; texture pellucido-herbaceous ; sori in a continuous or 

 slightly interrupted line along the upper edge. Hk. Sp. 1. p, 205. t. 61. B. 



Hab. Philippine Islands and Borneo. 



6. L. Seemanni, J. Sm. ; rhizome short-creeping ; st. wiry, flexuose, 3-6 in. 1. ; 

 fr. 6-12 in. 1., about 1 in. br., simply pinnate ; largest pinnae ^-| in. 1., ^ in. 

 deep, the same shape as those of L. cultrata, but the teeth, especially the lower 

 one, deeper and the texture thinner. J. Smith in Bot. Herald, p. 239. 



Hab. Bay of Choco, Panama, discovered by Dr. Seemann. Perhaps an American 

 form of L. cultrata. 



7- L- cultrata, Swartz ; rhizome short-creeping ; st. wiry, flexuose, 3-6 in. 1. ; 

 fr. 6-12 in. 1., about 1 in. br., simply pinnate ; largest pinnce ^-f in. 1., ^ in. 

 deep, not imbricated, the lower margin straight or slightly curved, usually 

 upwards, the upper edge slightly lobed, so that the continuity of the line of the 

 fructification is broken, sometimes nearly entire, lower pinnae stalked ; texture 

 coriaceo-membranaceous. Hk. Sp. 1. p. 203. Hk. Sf Gr. Ic. t. 144. Hk. Fil. 

 Exot. t. 67. L. Lobbiana, Hk. Sp. 1. p. 205. t. 62. C. L. gracilis, Blume, Hk. 

 E. C. j3, japonica ; fr. 2-3 in. 1. ; pinnce nearly triangular, with the point at 

 the base, upper edge nearly entire. 



Hab. North of India, ascending in the Himalayas to 4,000 ft. ; Neilgherries, 

 Malayan Peninsula and Islands, Bourbon ; and gathered lately by Mr. Hill in Queens- 

 land, by Dr. Meller in Madagascar. /3 is a remarkable variety discovered by Mr. Oldham 

 in Japan. 



8. L. botrychioides, St. Hil. ; st. 4-6 in. 1., wiry, erect, polished, dark chesnut- 

 brown ; fr. 9-12 in. 1., 1-1^ in. br., simply pinnate ; pinnce ^ in. each way, with 

 only the inner third of the lower half cut away, the lower line more or less 

 decurved, the upper line broadly rounded, scarcely lobed, and the outer margin 

 broad and blunt ; texture herbaceous ; rachis naked, polished ; sori in a continuous 

 line round the upper and outer edge and the inner half of the lower one, the 

 outer valve projecting beyond the inner. 



Hab. Brazil. Burchell, 4402. Probably this is only an unbranched form of L. 

 flabellulata, which, however, is not known to occur in the New World. Our description 

 is taken entirely from Burchell's specimens named by Metteniua. 



9. L. dubia, Spreng. ; rhizome short-creeping ; st. close together, wiry, 3-6 in. 

 1. ; Jr. 4-8 in. 1., 1^-2 in. br., simply pinnate ; pinnce f-1 in. J., not more than 1 in. 

 br., the upper edge crenated towards the gradually narrowing point, even the upper 

 ones with usually -| in. between them, often not truly dimidiate, but with the 

 costa becoming central towards the point ; texture pellucido-herbaceous ; line & 

 the sori not interrupted till it reaches the cremations of the outer third of the 

 upper margin. //. bp. I. p. 209. t. 64. C.
