the end of which functions :is a triclionyne, and a cluh-shaped antheridium. Papulospora 

 imuj/i ijii-n iloison is :m asexual Btage of Ascobolus magnificus Dodge. The intrahyphal my- 

 celium found in old cultures is simply a case of "Durchwachsungen" or "cordon interne." 

 The strains here reported, winch were obtained from germinated papulospon-s or ascospores, 

 were self-sterile in the experiments conducted, but always produced papulospores. Sexual 

 reproduction occurs in cultures containing two si rains properly chosen." ■ //. /,*. Rosen.

772. Sawhney, Kali Das. The vascular connections and the structure of the tendrils 

 in some Cucurbitaceae. Jour. Indian Bot. 1 : 254-262. 7 fig. 1920. — The author has exam- 

 ined the vascular anatomy of the node and the vascular connections of the nodal appendages 

 of 12 species of cultivated Cucurbitaceae. Tendrils, buds, and floral axes are connected with 

 the nodal plexus of the inner ring of 5 cauline bundles, while the leaves are connected with 

 the outer rings of cauline bundles. He concludes that the vascular connections and struc- 

 ture of the basal part of branched tendrils show that they are homologous with ordinary shoots; 

 that the arms of branched tendrils and the upper part of simple tendrils are homologous with 

 leaves; and that simple tendrils have been derived from branched tendrils. — Winfield Dudgeon.
