654 MONOCOTYLEDONEA. THEMEDA . 
Racemi faseieuliformes in apice culmi ramorumque panieuls 
folios® solitarii, cum pedunculo continui nec articulati. Spicularum 
paria dua infima homogama, c' v. neutra, mutica, ita arcte sibi 
approximata ut eorum spiculz vertieillum forment spurium, tetrame- 
rum, reliquas spieulas involuerantem ; spiculze involucrantes florem c 
unum triandrum foventes v. raro neutrz, in quoque pari aut ambze 
sessiles aut altera brevissime pedicellata. Paria superiora heterogama 
1—3, summum cum spicula terminali c ternionem efficiens ; eorum 
spiculæ pedicellatze involuerantibus simillimze, sessiles vero 8, formå 
ab illis diverse, sepissime aristatze, cum rhachi oblique artieulatze, 
disjunetze basi callum ssepe acutum barbatum exhibentes. Harum 
gluma I= plerumque coriacea, fructifera indurata, spadicea v. atro- 
fusca; II“ dorso late rotundato-carinata; carina coriacea, juxta cari- 
nam utrinque profunde sulcata, marginibus membranacea; IM 
hyalina; IV* plerumque a basi hyalina uninervi in aristam validam 
perfectam abiens, raro linearis, mutica v. imperfecte aristata. Palea 
nulla v. obsoleta. Lodieule cuneate, glabrz. Stamina 3. Stigmata 
infra spieule apicem v. prope ejus medium exserta. Caryopsis lineari- 
obovata, utrinque convexa, latere embryonis bisulea, embryone 
caryopseos medium quante. 
Gramina sepius elatiora, robustiora, plerumque perennia, panicula 
foliosa, racemis erebris abbreviatis singulis pedunculo intra spatham 
propriam ineluso v. raro exserto fultis insignia, zonam tropicam atque 
 Subtropicam orbis antiqui incolentia.— Culmi multinodes. Vaginæ infe- 
riores et medii arctz, internodiis breviores, superiores florifer® dila- 
tate, laminam ferentes. Laminz lineares v. sublanceolato-lineares. 
Panieula culmi dimidium v. plus oceupans. Spathze proprize eymbifor- 
mes, aphyllz, carinatze, multinerves. Spiculæ in quovis racemo 7—11 : 
4 involucrantes per paria dispositze, quze vero in quibusdam speciebus 
ita arete sunt superposita, ut eadem altitudine enasci videantur. 
Cujusque paris spicula altera sessilis, altera aut subsessilis (tum callo 
longiori a sessili distinguenda) aut pedicellulo inserta eodem prorsus 
modo ae in speciebus quibusdam Andropogonis sect. Cymbopogonis 
(e. gr. A. diplandro, A. multiplici, A. arrhenobasi, anthistiroidi aliis). 
Spieule involuerantes post delapsas fructiferas aut omnes in apice 
pedunculi persistunt aut ez qua pedicellulo fuleiuntur, ab hoc dis- 
junguntur. Earum gluma I™ herbaceo-chartacea, plurinervis, dorso 
plana, marginibus anguste carinato-implieata ; II membranacea, I^ 
subzquans, lanceolata v. lineari-lanceolata, acuta, 3-nervis, margini- 
bus implicatis hyalinis ciliatis; IIP illis paullo—'/, brevior, hyalina,
