C. (Physapteris) Lindheimeri— Phy-sap'-ter-is ; Lind-lieim'-er-i (Lind- 



heimer's), Hooker. 



A very pretty, greenhouse species, native of Western Texas, New Mexico, 

 and Arizona, growing probably in crevices of exposed rocks ; it has also 

 been collected in the Sierra Madre of Mexico and near San Luis Potosi. Its 

 fronds, Sin. to 6in. long, l^in. to 2in. broad, are produced from a thin, slender 

 rootstock, several inches long, very nearly black, and bearing a few rusty- 

 coloured scales at the base, and are borne on wiry, dark chestnut-brown 

 coloured stalks 3in. to 6in. long and thinly clothed with narrow- spear -shaped 

 scales. The leaflets are numerous, spear-shaped, and cut into many linear- 

 oblong pinnules (leafits), which are again cut into numerous minute, roundish 

 segments. The upper surface is webby with slender branching hairs, which 

 are much entangled and constitute a heavy tomentum of exceedingly delicate 

 hairs having no evident articulations. When the frond is very old this 

 webbiness partly wears oiF, while the colour of the scales of the lower surface 

 gradually becomes deeper. The whole under- surface is densely clothed with 

 imbricated, ferruginous (overlapping and rusty coloured) scales. The outer 

 margin of the segments is so revolute as to make them appear almost pouch - 

 hke. The sori (spore masses), disposed a few to the margin of each pinnule, 

 are entirely hidden beneath the scaly and woolly covering. — Hooker^ Species

C. Lindigii — Lin-dig'-i-i (Lindig's), Mettenius. 



A stove species, from the Andes of Granada, with lanceolate (spear-shaped) 

 fronds, 4in. to Sin. long and about lin. broad, borne on densely-tufted, naked 

 stalks lin. to 4in. long and chestnut-brown in colour. The leaflets are sessile 

 (stalkless) and cut down below to a narrow wing into oblong, blunt pinnules 

 (leafits) of a thin, yet firm texture, and pale dull green on both surfaces. 

 The sori (spore masses) are closely set, six to eight to the lowest pinnules. —
