312 MR. W. GRIFFITH ON THE GENUS GNETUM. 



Fig. 35. The same, the embryo varied in shape. 



Fio-. 36. The same, with one of the cotyledons removed, showing the rudimentary plumule. 



Fig. 37. Portion of the centre of the funiculus, showing the spiral disposition. 



Fig. 38. Portion of inflorescence of G. apiculatum ; the ovules are totally concealed and surrounded by 

 very dense brown hairs. Exsertion of the stamina has taken place. 



Fig. 39. Portion of inflorescence of G. scandens ; the ovules are totally concealed, and the filaments are 

 exserted to a considerable length; the transverse opening through the male perianth is re- 

 presented. 



Fi". 40. A verticil viewed from above, showing the ovules in situ, and partially surrounded with hairs. 

 In this species the ovules are arranged in about two series, and the fissure is visible at the 

 apices of some. 



Fig. 41. Portion of inflorescence of G. Brunonianum, including one verticil with its obsolete ring (invo- 

 lucre). In this species the ovules are completely exposed at this period, their bases being sur- 

 rounded with hairs ; they are arranged in one series ; some of the stamens are exserted. 



Fig. 42. Portion of the spike of G. scandens, representing the ovules fully exposed, and the exsertion of 

 the tubular prolongation of the additional or third membrane. 



Fig. 43. Stamen of G. Brunonianum (?) at an early period; the filaments are still distinct at their bases ; 

 the number, direction, and termination of the vascular fasciculi are shown. 



Fig. 44. Male flower of G. Brunonianum (?) before dehiscence, 



Fi". 45. Stamen of the same, the base of the perianth partly remaining; the anthers have dehisced. 



Fig. 46, Pollen of the same. 



Fig. 47. The same after immersion in water.
