"3. oPHioaLossm^ § ecophioglossuil 44-5 



§ Enophioglossmn. Fertile spike single, arising from the base of the barren 

 segmaU. Sp. 1-6. 



1. O. Jmif'ir.iatm, L. j notstock s%htly tuberous; fr. 1-3 in. 1., the sterile 

 diTision placed below the centre, ^1 in. 1., 1^2 lin. br^ linear-lanceolate, the point 

 binntish, the base narrowed ; textwre thick, no midrib, and the yeins indistinct ; 

 fertile spike J-J in. 1., the pedunde firm, J-1^ in. 1. when mature. — Mi. B. P.

Habk SSiores of the Mediteiranean, and as fax nortli as Gnemsey, Azores, Hadeita, 

 Guinea Coast. — The Emopean plant ia developed in winter, whilst in Britain O. vul- 

 gatam is not matore till Jnne. 0. gramiKemm, Willd., from North and Feninsnlar India, 

 is probablj identical, and the same may be said of the Anstralian and New Zealand 

 0. grammeam, B. Br. The Xew Zealand 0. mmimmn, Golenao, is not more than 1 in. 

 high, with the barren segment 3 lin. L by half as broad ; and three closely-allied forms 

 have been ga^iered by Dr. Welwitsch in Angola, — O. gememanam, Wdw., 1-1| in. L, 

 barren segm. near the base, i-f in L, 2 lin. br. ; O. luso-afrieamim, Welw., 4 in. ]., barren 

 e^m. central, 1| in. L, 2 Im. br. ; and 0. graeSliaam, Welw., 1| in. L, barren s^m. 

 central, tmly linear, acnte, 1 in. or le^ L, nnder 1 lin. br. The African forms have 

 lately been monographed by Dr. A. Biann in Kohn's Alices Africanae. 



2. O. tiAdbm, Wdw. MSS. ; rootMode slightly tnberons ; fr. 1-2 in. L, the 

 sterile diyision placed very near the base, roundish, ^ in. each way, without a 

 haft, often adpr^sed to the surface of the ground, diick in texture, the veining 

 hidden ; fertile spiie J-f in. 1., the reddish peduncle f-1 in. 1. when fully 

 matured. 



Hab. Fongo Andongo, Angola, 2,400-3,800 fi. ; Wdmiteh 33.— Most like 0. bulbotum 

 bnt smaller, with the barren segment snb-basaL 



3. O. tmlbosum. Hichx. ; rootstock tuberous, |-f in. thick ; Jr. 2-t in. L, the 

 sterile division placed considerably below the middle, ^1 in. L, ^ in. br., ovate, 

 without a haft ; texture stouter than in O. vulgctum, the midrib and veining 

 quite indistinct ; fertile spike ^-k ™- l-> the peduncle 1^2 in. when fully 

 developed.. — O. crotalophoroides, fFaU. O. tuberosum, Hk. Sf A. O. opacum, 

 R. Br. Hk. <fi Gr. t. 60. O. stipatnm, CoUa. 



Hab. Iionisiana and Florida to Chili and Tristan d'Acnnha ; and a Malay specimen 

 &om ProL De Vriese agrees with the American plant. 



4. O. midicaule, L. fil. ; roatstodt slightly tuberous ; fr. 2-4 in. L, the sterile 

 division placed not far &om the base, |-1^ in. 1., ^-^ in. br., ovate or oblong, 

 without a haft or with only a slight one, the texture thin bnt the veins not 

 distinct ; yerfife spike f in. 1., the peduncle often 2-3 in. 1., very slender. —

Hab. America from the Sontbem ITnited States southward to Brazil ; Xew Caledonia, 

 Malaccas, Peninsular India, Guinea Coast, Angola. — Whether this be tile origin^ iRuZi- 

 emdt is not qnite dear, bnt it is the plant figured under that name by Swartz and Eunze. 

 To the type bdong 0. gpoRemeage, Mart f . 73, 0. suriaameme, Beich., and O.fiaviemde, 

 Elotzsch, and probably 0. mobwcanum, Schlecht. Ennze's fig. a, 0. Wightii, Hk. ft 6r., 

 and O. etUptUnaa, Hk. ft Gr. t. 40, are larger in size, with the sterile s^ment as thin 

 and the venation as plain as in refuiiiafim, 2 in. or more I., |-f in. br., and the stem 

 longer. 0. maerorbizum, Eze. t. 29. fig. 1 (&om Guiana and Branl), is a mnch-reduced 

 variety, not more than l{-2 in. hig^ witii the sterile division not more than 4 in. L, 

 iin.br. The Sandwich Island 0. toneimtum. Brack, t. 44, is most like this, bat the 

 barren s^ment is farther from the base of the stem ; and this also appears to be the 

 case with the Chilian 0. mdipUleme, Bemy. 



5. O. mi^atum, L. ; rootstock not tnberons ; fr. 6-9 in. L, the sterile division 

 generally placed about the middle, 2-4 in. 1., J-2 in. br., ovate or OTateH)blong
