	His problem is that his catalogue only allows point coordinates but a "nebulous mass" is not described by a point. Hence, he states that there is an extended nebula with the shape of an ivy leaf, which should be drawn by the globe maker so that it contains the three stars listed. Toomer (1984) identifies these stars as 15 (c), 7 (h) and 23 (k) Com. Although only the last one has the term "ivy leaf" in its description, this term refers to an area that encompasses all three (and possibly even more, fainter) stars.
