III. GNETOIDEAE (i P tubular, A 2 sessile on thread-like 

 elongated axis; 9 P pipe-like, ov. with i integuments. 

 Usu. climbing ; fls. in spikes, P becoming fleshy) : 

 Gnetum. 



Gnetales, a class of Gymnospermae ; only fam. Gnetaceae. 



Gnetum L. Gnetaceae. 15 trop. Most are climbing shrubs, a few erect 

 shrubs or small trees. L. decu>sate, exstip., simple, evergr., leathery. 

 Fls. dioec., in spikes which are frequently grouped into more com- 

 plex infls. The spike bears decussate bracts, in wh< se axils are 

 condensed partial inrls. of a large number of flrs. (cf. Labiatae), about 

 3 8 in the ?, but more (up to 40) in the <?. These fls. form whorls 

 round the stem, and are intermingled with numerous hair-structures. 

 At the top of each nodal group of the 3 infl. in most is a single ring 

 of? fls., usu. with only i integument and infertile, sometimes with 2 

 or even 3 integuments and fertile. The 5 has a tubular (2-leafed) P, 

 from the top of which the axis projects ; at the tip of the axis, right 

 and left, are two sessile i-loc. anthers. The ? has a tubular P like 

 that of Ephedra, surrounding a single orthotr. erect ovule with two 

 integuments; the inner of these projects at the apex of the fl. But 

 there is much difference of opinion as to the morphology of these 

 three envelopes. After fert. the P becomes fleshy, the outer integu- 

 ment woody, forming a drupe-like fr. G. Gnemon L. (Malaya) and
