A species resembling Krhcfflira hhincoi Merr.. hut (liHeriug from that species 

 in its elongated branches, larger heads and more numerously-celled fruits, those 

 in /S'. blancoi being usually, if not always, 5-celled. It is apparently more closely 

 allied to »S'. cephalotes Harms, of the Malay reiiinsula. than to S. hUuicoi, but 

 seems siiiriciently distinct from that s|)ecies. The niatuic fruits or heads are 

 very suggestive of those of some species of r<ni(hiiiiis in the group of /'. jiiscicularis 

 L;im.
