36 ILLUSTRATIONS OF 



oblong, acuminated gradually, and sharply attenuated at the 

 apex, rounded or subtruncated, and somewhat insequilateral at 

 base, 3 inches long, 1| inch broad, upon a thick short petiole 

 of 2 lines in length. The flowers, sometimes in pairs, grow late- 

 rally at the base of the petiole ; the peduncle is refracted, | to 

 1 inch long, and covered with long glandular hairs mixed with 

 shorter stellate pubescence ; the calyx, also tomentose, is 8 lines 

 long, 6 lines across, inclosing a small globular berry 4 lines in 



diameter*. 



Marckea. 



Of this genus no further information has hitherto been re- 

 corded beyond the short account first published by Uichard, and 

 so little has its affinity been understood, that it was considered 

 by Endlicher as related to the Nicotianece. Its alliance however 

 is evidently with Solandra and JuanuUoa, agreeing with the latter 

 genus in the structure of its calyx and fruit, and diflFering in the 

 hypocrateriform shape of its corolla, with broad, expanded and 

 almost rotate border, and in its scarlet colour. 



From a plant in Sir William Hooker's herbarium, with only a 

 single flower and fruit, I have been able to make the following 

 analysis, which in some respects is incomplete, as I was anxious 

 not to injure the specimen. 



Marckea, L. C, Richard, Lamarckea, Pers, — Calyw 5-sepalus, 

 persistens, vix augescens : sepala lanceolata, acuminatissima, 

 imo angustata, primum ultra medium, marginibus ciliatis, in 

 tubum pentagonum valvatim conniventia, hinc superne lineari- 

 attenuata, erecta, libera, dein in fructu omnino sejuncta. Co- 

 rolla hypocrateriformis, tubo elongato, cylindrico, fauce sub- 

 inflato, limbo 5-partito, laciniis oblongis, rotundatis, rotato- 

 expansis, subreflexis, sestivatione imbricata. Stamina 5, sequa- 



lia, paulo supra basin corollse orta, basi lanata, filamenta erecta, 

 tenuia, antherce in faucem corollse inclusse, 2-loculares, lineari- 

 oblongse, lobis disjunctis, puncto medio affixis, rima marginali 

 longitudinaliter dehiscentibus. Ovarium 2-loculare, placentis e 

 dissepimento utriuque eruciatim tenuiter partientibus, hinc in- 

 crassatis undique ovuhgeris, ovulis angulo basali nexis, adscen- 

 dentibus. Stylus tenuis, longitudine staminum. Stigma in- 

 tegrum? Bacca fere capsularis, exsucca, evalvis, pericarpio 

 tenui indehiscente, sepalis persistentibus tecta, oblonga, 2-sul- 

 cat^, 2-locularis. Semina plurima, imbricatim disposita, ob- 

 longa, acuminata, imo gibba, hilo in angulo basali, adscen-
