494. MR. SPENCER LE M. MOORE—PHANEROGAMIC BOTANY 
pedunculatee. Flores parvi, intra spatham solitarii vel bini, pedicellati. Capsula e 
spathà exserta. 
Genus memoratu dignum, habitu ad Calydoream accedens, ab eà vero abhorret, prseter 
alia, styli ramis longe disparibus (itaque generibus ab omnibus e tribu Sisyrinchiearum 
stylis staminibus antipositis). Ob antherarum appendices singulares plane diversa 
videtur ab omnibus Morearum, quarum habitus insuper plus minus alienus. 
ZYGELLA GRAMINEA (sp. nov.); bulbo subgloboso, parvo, tunicis bruneis in collum 
supra bulbum longiuscule productum dense obtecto; foliis radicalibus anguste 
linearibus, acuminatis, satis ample vaginatis, nune elongatis, nune brevibus, non- 
nunquam ad vaginam meram fere vel omnino reductis; caule breviusculo vel sat 
elato, gracili; foliis floralibus majoribus solemniter florem infimum suffulcientibus 
foliis radicalibus subsimilibus ; pedunculis gracilibus; spatharum valvulis lanceo- 
latis, valvulà inferiore acutá, superiore pedicello arcte circumvoluto truncata ; 
perianthii segmentis spathulari-obovatis obtusis, antheris filamentis «equilongis; 
stylo filamentis fere 2-plo breviore, ramis sursum ampliatis. 
Hab. Crescit ad Santa Cruz, ubi mens. Nov. florescit. (N. 733.) 
Bulbus circa 1-0 em. long. et lat., basi parce radicifera, radices debiles, simplices, rarius 
breviter ramos. ; collum 1:0-1:5 cm. long. Folia radicalia majora 8:0-12:0 cm. long., 
01-0'15 cm. lat, vagine ad 0'3 cm. lat., sursum angustate, scariosee. Caulis 
infra folia floralia ad 24-0 em. alt., modicus circa 16:0 cm., erectus, ad 0'1 em. diam., 
apice leviter geniculatus. Folia floralia 5:0-9:0 em. long., ad 0:2 cm. lat., basi sat 
ample vaginata. Pedunculi usque ad 9:0 em. long. (plerique vero breviores), erecti. 
Spathæ valvula inferior circa 1:5 cm., superior circa 2:5 em. long. Pedicelli ad 
3'0 cm. long. Perianthii segmenta nunc cyanea, nunc ceerulea, basi dilute lutescenti- 
viridia, ibidem purpureo-maculata, ad 0:1 cm. connata ; segmenta exteriora 1:5 cm., 
interiora 1:2 em. long. Filamenta 0:25 cm. long. Anthera tota 0'4 cm. long. 
Pollinis grana globosa, tuberculata. Stylus vix 0-2 cm. long., imá basi leviter 
incrassatus, rami quam ipse 2-21-plo longiores; lamellae 0°15 em. long. Capsula 
ad 0:5 cm., extra spatham exserta, 0°5 em. long. vix 03 em. lat, ejus valve 
obtuse, modo 0-1 em. long. Semina tota 0:075 cm. long. ovoidea, brunea, alá quam 
corpus ipsum seminis 23-plo longiore appendiculata. 
This is a curious genus, apparently not very closely allied to any other. In habit and 
floral structure it is unlike most genera of Moraee, coming closest probably, in these 
respects, to Alophia. The habit is that of the subtribe Cipurese of Sisyrinchiee, the 
distinctively American portion of the order, so much so, indeed, that the plant might easily 
be mistaken for a species of one of that subtribe’s genera until dissection should reveal the 
difference. From all these genera Zygella is at once distinguished by its curious stamens, 
and, among them, Nemastylis alone has divided style-arms, but style-arms which are 
subulate and quite unlike the lamelliform organs of Zygella. "There can, I think, be no 
reason to doubt our plant’s claim as being an example of a new genus, which seems to 
connect in some measure the two tribes Moreee and Sisyrinchiew, since it unites in itself 
. the anti-staminal style-arms of the former and the habit of the latter tribe—hence its 
proposed name, from ¿¿yów, to join together.
