440 69. ANGIOPTERIS. 70. MARATTIA, EUMARATTIA. 



GEN. 69. ANGIOPTERIS, Hoffm. 



Caps, opening by a slit down the side, sessile, very close to one another but not 

 concrete, arranged in linear-oblong or boat-shaped sori near the edge of the frond. 

 TAB. IX. fig. 69. 



1. A. evecta, Hoffm.; caud. erect, 2-6 ft. high, l|-2 ft. thick ; st. swollen and 

 articulated at the base, furnished with two large leathery auricles, which remain 

 attached to the caudex after it falls ; fr. 6-15 ft. 1., bipinnate ; pinnce 1-3 ft. 1., 

 spreading, the lowest the largest, the rachis swollen at the base ; pinnl. 4-12 

 in. 1., -! in. br., linear-oblong, sessile or short-stalked, the point acuminate, 

 the edge entire or slightly toothed ; texture subcoriaceous ; both sides naked, 

 smooth, shining; veins subparallel ; sori consisting of 8-15 caps., in close rows 

 near the edge, almost hiding the inferior fimbriated involucre. Hk. & Gr. 

 t.36. HLFil.Ex.t.15. 



Hab. Himalayas and Japan to Ceylon, Madagascar, New Caledonia, Queensland, and 

 Society Isles. We cannot determine more than one clearly-marked species, but Presl 

 defines ten, and De Vriese sixty. There is a considerable range of varLuion in the tex- 

 ture of the pinnae and closeness of the veins and sori, and tbe number ot capsules which 

 compose the latter; and in many of the forms there is a free veiulet, which is very 

 variable in length and distinctness, which begins at the edge of the frond in the inter- 

 space between the veins proper. Psilodochea salici/olia, Presl, is an entirely obscure 

 plant, supposed to have been gathered in Lahore, said to be like A ngiopteris, but without 

 an involucre. 



GEN. 70. MARATTIA, Sm. (See page 525.) 



Caps, sessile or stalked, 4-12, concrete in boat-shaped synangia, which consist 

 of two opposite rows of capsules, and open by slits down their inner faces. A 

 well-marked genus, extending all round tlie world within the Tropics, and a little 

 beyond the southern one. TAB. IX. fig. 70. 



Eumarattia. Synangia furnished with an obscure fimbriated inferior invo- 

 J lucre. Sp. 1-2. 



1. M. fraxinea, Smith ; st. 1-2 ft. 1., 1-1^ in. thick, smooth, deciduously scaly 

 and swollen in the lower part ; fr. 6-15 ft. 1., bipinnate or casually tripinnate ; 

 pinnce 1-2 ft. 1., often 1 ft. br., pinnl. oblong- lanceolate, 4-6 in. 1., -l in. br., 

 the apex acuminate, the edge entire or serrulate, the base cuneate or slightly 

 rounded ; texture coriaceous ; surfaces naked ; veins simple or forked, the rachis 

 of the pinnae sometimes slyjhtly winged ; synangia usually submarginal, in close 

 rows, J-l^ lin. 1., the sidi/s vertical, the receptacle linear, with 6-12 caps, on 

 each side. 



Hab. Guinea Coast, Angola, Zambesi-land, Mascaren Isles, Natal, Cape Colony, Neil- 

 gherries, Ceylon, Philippines, Malaccas, Polynesia, New Zealand, Queensland, Norfolk 

 Island. The typical plant (Smith, Ic. inedit. t. 48 ; Beddome, t. 79) has pinnules l-l^ 

 in. br., serrulate principally at the apex, numerous forked veins, and submarginal synan- 

 gia, with 10-12 caps, on each side. To this belong M. sorbijolia, Bory, and M. eleyans, 

 Endl. From this we cannot separate clearly many plants which have been regarded as 

 distinct ; of which the principal are M. salicifolia, Schrad. (Kze. t. 38), including M. Dre- 

 giana and natalensis, Presl (South Africa), pinnules sharply toothed throughout, often 

 only i-t i- br., reins more distant, synangia with about 6 caps, on each side, not so 

 close or so near the edge ; M. salicina, Sm., De Vriese, tab. 3. fig. 18 (Society Isles), 



species, and give nine large folio plates to illustrate the characters of these and the ana- 

 tomical structure of the genera. In all of them the caudex is a succulent irregularly- 

 shaped tuberous mass, upon which the stems are articulated, and the latter are furnished 

 at the base with a pair of large flap-like auricles, which are leathery in texture when dry.
