The above masterly account of the subjects represented in plates 248 and 249, the reader will observe, is from the 
pen of Professor Von Martius of Munich ; and I have further to thank that excellent friend for the following 
valuable Synopsis of the families Eriocaulee and Ayrideæ (formerly comprised under Restiaceæ) in the Herbariums 
of the Hon. East India Company at present under my charge.

Character naturalis. Flores minuti, plurimi in capitulum andro- 
gynum per spiras arctissimas compacti, super rhachin (receptaculum) 
(planum aut convexum, nudum aut pilosum), persistentes, singuli 
fulti bracteå (squamå, Br.), quarum extime sæpð vacuæ involu- 
crum constituunt. Calyx triphyllus: foliis binis anticis, tertio 
postico (A); aut diphyllus. Corolla tripetala (y), aut dipetala, sub- 
stipitata, aut petalis (in â ) deorsum longiusculé connatis tubæformis 
vel infundibuliformis, in floribus fæmineis semper distinctis. Masculi 
in disco capituli. Stamina sena aut quaterna, longiora corollæ divi- 
sionibus opposita. Antheræ basifixæ, ovato-didymæ, bilocellares, 
locellis medió longitudinaliter bivalvibus. Pollen globosum. Fæminei 
in ambitu capituli. Ovarium (superum) triloculare, globoso-trilobum, 
loculis duobus posticis (y), aut biloculare, didymum (rarissime, in 
speciebus brasiliensibus, quadriloculare). Ovula solitaria, pendula. 
Stylus centralis, basi simplex, sursum in crura tria (rarô duo, raris- 
simé quatuor) subulata, cellulis longiusculis stigmatosa, divisus, per- 
sistens. Capsula tenuiter membranacea, globoso- ovato- aut oblongo- 
triloba bilobave, dehiscentiá loculicidá, petalis in sinubus valvularum 
persistentibus cincta, tandem hygroscopicé se contorquens. Semina 
minima, oblonga aut cylindracea, solitaria, pendula, ad hilum acu- 
tiuscula. Testa simplex, cristis longitudinalibus (semper 12?), quee 
pilis tenuissimis pellucidis apice clavæformibus instruuntur. Albu- 
men farinaceum, album, semini conforme. Embryo ovato-globosus, 
minimus, in extremitate hilo opposita, hinc teste, indé albumini con- 
tiguus.—Herbæ annuæ perennesvê, acaules ; rarius herbæ aut suffru- 
tices caulescentes. Radices plurime fasciculatæ, albidae. Caulium 
loco in pluribus rhizoma, nunc tenue, nune crassum, carnosum, 
ubique phyllophoron ; in paucioribus caulis adest fluitans radicans, | 
aut erectus divaricato-ramosus, foliosus, subinde inter pedunculos 
lateraliter proliferus. Folia numerosa, in acaulibus speciebus omnia 
radicalia rosulata, caulina alterna, sessilia, basi membranaceá va- 
ginantia, angusta, parenchymate regulari rectangulo sæpð quasi fe- 
nestrata, rard ob lacunas centrales seriatas quasi fistulosa, lætè viridia, 
basi membranaceo-albida. Scapi e rhizomatibus aut pedunculi e cau- 
libus, solitarii, pluresvé aggregati, certo angulorum numero distincti, 
e vagina prodeuntes, ipsorum basin amplectente, cylindrica, ore 
transversé aut oblique truncata ; singuli singulum ferentes capitulum 
multiflorum. Bracteæ (squamæ, Br., convenientes paleis Composi- 
tarum) periphericæ plerzeque vacuæ, firmiores siccioresque involucrum 
formantes, nude; interiores teneriores singule florem emittentes atque 
fulcrantes, anticé barbatæ aut villosæ pilis albis opacis, rard glabræ. 
Calyces sæpð cinerascentes aut plumbei. Corollæ laciniæ aut petala 
sepé cristulis forme varie (palmatis, lobatisque, quasi essent pili 
confluentes et connati) apice dorsove ornata. 
Observatio. Præeunte cel. Richardio (Annal. du Mus. d'Hist. Nat. 
tom. 17. p. 52), quem jam cel. Kunthius (Nov. Gen. vol. i. p. 251) 
insequutus est, Eriocauli genus, unà cum Tonina Aubl. (Hyphydra 
Vahl.) proprium plantarum ordinem efformare judico, inter Restia- 
ceas et Xyrideas medium. De hujus notis affinitatibusque disserere 
heic locus non est. Id unum moneo, cardinem diagnoseos versari 
in partium perianthii dispositione, antherarum fabrica, ovulorum di- 
rectione, ovarii loculis monospermis distinctis, placentatione imme- 
diata, seminum hirsutie singulari, embryonis situ, habitu. Calycis 
dispositio in Eriocauleis et Xyrideis: A, in Restiaceis: v ; quam 
quidem perianthii partem verum esse calycem neque bracteas ap- 
proximatas (quod Tonine levis inspectio indigitare videretur) autumo. 
In illis porró ordinibus antheræ bilocellares, in Restiaceis ferè omni- 
bus (quas examinevi) unilocellares. Conveniunt Eriocauleæ cum 
Restiaceis ovarii loculis monospermis, ovulis pendulis, eåque notå 
differunt a Xyrideis, quæ ovula in longis funiculis peritropia plurima 
erigunt, intra capsulam unilocularem (attamen tribus phyllis factam). 
Hec sufficiant.
