Parasia debilis (Welw.) Hiern in Catal. Welw. Afr. PL I (1898), 708 a . 



Ausserordentlich schmächtig und zart, mit zum Teil dem Boden an- 

 liegenden zarten Zweigen und einem fast fleischigen Wurzelstock, die 

 zahlreichen, fleischigen blütentragenden Stengel höchstens 5 cm hoch. 

 Die wenigblutigen, oft auch nur zwei- oder einblütigen Infloreszenzen 

 sind, wenn sie überhaupt verästelt sind, cymös verzweigt. Die Kelch- 

 abschnitte der « milchweissen » Blüten sind 4 bis 4 1 /» mm lang und 



apice rotundato vix apiculalis; stigmate elongato-clavato, glanduloso-pubescente ; 

 quam Stylus longiore, apice obtusiusculo bilobo. 



Herbula perparva, forsitan parasitica, habitu Sebœœ pusillœ (Lagenias pus. 

 E. M.) non absimilis, 1 — 2 pollices alta. Rhizoma carnosulum, oblique descen- 

 des, fibrillis admodum fragilibus elongatis limum humidum perrepens, e collo 

 caules paucos debiles vix bipollicares, simplices vel fastigiatim ramosos emittens. 

 Folia in uno eodemque specimine varia, plerumque lanceolata et acuminata, 

 rarius ovata et obtusiuscula, summa hinc inde anguste lanceolata vel linearia. 



Cymulae fastigiatse, pauciflorae, hie depauperatee bi-uniflorse. Flores una cum 

 calyce 6 — 7 lin. longi, erecti. Calycis alae brèves, ejusdem segmenta basi late 

 membranaceo-marginata, apice subulata et divergentia. Corolla alba, tenera, tubo 

 calycem constanter superante, faucem versus modice ampliato; limbi 5-fidi lobi 

 campanulatim patuli, tubo duplo subtriplove breviores, apice rotundata-obtusi, 

 absque ullo mucrone vel apiculo. Stamina, antherarum fabrica et stigma nee 

 non Capsula et semiua fere omnino speciei antecedentis, a qua tarnen praesens 

 rhizomatis natura, corolla alba duplo minore, tubo corollino elongato et limbi 

 lobis rotundato-obtusis inapiculatis sine difficultate distinguitur. 



Observatio. — Quoad herbulae durationem incertus permaneo ; habitus quidem 

 et cauliculorum tenuitas plantam annuam indigitant, ast rhizoma crassiusculum 

 et subcarnosum forsitan stirpern biennem vel imo per plures annos durantera 

 sustentât. 



2 Pungo Andongo. — A flaccid, parasitical little herb, 1 to 2 in. high, appa- 

 rently not annual ; rhizome rather thick, whitish, somewhat fleshy, brittle. 

 creeping obliquely among marsh herbs ; stems numerous, rather fleshy, very 

 brittle. subtetragonal; flowers milk-white, pentamerous, cymosely fastigiate; 

 calyx deeply cleft ; corolla thin-fleshy ; the lobes obovate-oblong or obovate, not 

 mucronate, obtuse; the limb campanulate-spreading ; stamens inserted at the 

 middle of the corolla-tube or a little higher, included ; anthers introrse, 2-celled, 

 biglandular at the base; the connective fleshy, tumid, produced far beyond the 

 cells:ovary 2-celled; style straight; stigma elongated-clavate, velvety; capsule 

 globose, many-seeded. In grassy muddy places nearly dried up at the time, at 

 the Lagôa de Quibinda on the right bank of the river Guije, sparingly ; fl. and fr.
