Vahl s. X. carolinianam Walt. — quae tamen jam foliis cartilagineo-marginatis 

 carinaque sepalorum lateralium ciliata (haud fimbriato-serrulata) differt. 



Xyris valida Malme n. spec. — Caespitosa rhizomate brevi, adscendente, 

 radices crassas, spongiosas emittente. Folia manifeste disticha, rigida, linearia, 

 22 — 32 cm longa, 3 — 4,5 mm lata, oblique acuminata, summo apice saepe cur- 

 vato, crebre nervoso-striata, glabra, laevia (haud ruguloso-scabrida), nitida, 

 obtuse angusteque cartilagineo-marginata, sensim in vaginam dilatata satis 

 arctam, 8 — 10 cm longam, inferne castaneam nitidissimamque, margine superne 

 crebre minuteque ciliatam, inferne autem glaberrimam. Scapi axillares, saltem 

 usque 75 cm alti, ancipites v. crasse bialati, circiter 2,5 mm lati, laeves glabrique, 

 alis scabridulis, basi circumdati vagina subaph5dla, crasse acuteque mucronata, 

 usque 15 cm longa. Spica satis multiflora, obovoidea v. subglobosa, 8 — 10 mm 

 longa, 6 — 9 mm crassa; bracteae infimae duae carinatae acutaeque, ceterae 

 obovatae v. obovato-oblongae, 6 — 7 mm longae, 3 — 4 mm latae, omnino ecari- 

 natae, apice rotundatae et saepe crasse brevissimeque mucronatae, concolores, 

 obscure castaneae, superne opacae, inferne nitidae, nervis percursae 9 apice 

 tantum anastomosantibus, margine tenui subintegerrimo v. paullulum lacerato. 

 Sepala lateralia libera, subaequilatera, sublinearia v. anguste lingulata, circiter 

 6 mm longa, i — 1,5 mm lata, apice obtusissima, dorso carinata, carina satis 

 angusta praecipue superne crebre minuteque ciliata, in mucronem brevem, ob-

Species inter africanas fere maxima, perdistincta foliis rigidis, striatis, 

 nitidis, cartilagineo-marginatis, vagina margine superne ciliata, scapo bialato, 

 spica subglobosa, bracteis obovatis, satis angustis, area dorsali nulla. X. hato- 

 kanae N. E. Brown, mihi tantum e descriptione bona notae, forsan sit affinis, 

 at multis notis gravibus differt.

Eriocaulon Volkensii Engl. var. Mildbraedii Ruhl. n. var. Differt a typo 

 pedunculis longioribus, 18 — 21 cm altis, folia longe superantibus, capitulis majo- 

 rioLs ,5 — 12 mm latis, jam primo intuitu albo-villosis, floribus magis nigri- 

 cantibus.

 Sabinjo und ]\Igahinga, quellige Stellen auf Lichtungen im Bambuswald (bliihend
