 campanulatus, profunde 5-partitus, persistens. Corolla rotata, 

 tubo brevi, limbo S-partito^ laciniis oblongis, acuminatis, sesti- 

 vatione valvata. Stamina 5, erecta ; filamenta filiformia, brevia, 

 paulo supra basin corollse inserta, imo repente triangulariter 

 dilatata, et hinc in annulum fere coalita; anthercB oblongse, 

 2-loculares, basi emarginato-cordatse, loculis connectivo an- 

 gusto dorsali parallele connatis, longitudinaliter dehiscentibus.

 pimento adnatis. Stylus simplex, longitudine staminum, apice 

 iucrassatus, fistulosus. Stigma subintegrum, glandula gluti- 

 nosa 2-loba semi-immersa. Bacca ovata, calyce aucto tecta.

 nidulantia, testa scrobiculata, subscabra, hilo perforate in sinu 

 marginali. Embryo in albumen carnosum, subspiralis : coty- 

 ledonibus semiteretibus_, radicula 3-4-plo brevioribus. — Fru- 

 tices Brasilienses, dichotome ramosce-, folia alterna, vel gemina 

 altera minori [in twnonibus subfasciculata) , integra ; flores pe- 

 dunculati, axillares, vel in dichotomiis solitarii^ bini, vel plures

To tbe long and excellent description of Von Martins above 

 referred to, it is quite unnecessary to offer the smallest additional 

 remark, except that Gardner^ s plant which I collected at the same 

 time does not appear to me to offer any difference from that 

 figured by Martins, and that it is a little more hairy* : if 

 therefore it does not belong to this species, it most probably is 

 referable to W. pogogena. Of the following seven species I have 

 no knowledge whatever, beyond the short notice extracted by 

 Dr. Walpers from Dr.ySeudtner's description, to which I refer 

 the reader. >t --tft h;

* As Dr. von Martius's admirable work is within the reach of few per- 

 sons, and as it may be desirable to compare the above with its analogous 

 genera, I have given a figure with full details of the structure of this species, 

 which 1 first collected at Tejuca in 18;}3, and afterwards with Mr. Gardner 

 in 1837 (Gardn. no. 237) ; it will be shown in the * Illust. S. Anier, Plants^' 

 pi. 35.
