John, I think you are putting too much emphasis on this business of having a channel, or not having a channel. The plant growth habit is much like a stalk of celery except that on most leaves the groove/channel at the adaxial base usually quickly disappears, but not always completely. Adding to the confusion, some leaves show distinct, micro-longitudinal lines which are not channels.
This plant was one of those found at the Koko Crater, Hawaii (USDA # 19471) and tested for fiber production by the U.S.Dept. of Agriculture.
I'm attaching 2 closeup pictures that show this unique plant a little better.

Hermine I went into the group library and looked in your book Schweinfurthii pg 34 and ripped the picture (not the best in the world). This clearly shows a round leaf plant with a channel so I don't think this is schweinfurthii/erytraeae.
Sansevieria schweinfurthii Täckh. & Drar, Fl. Egypt 3: 305 (1954), contrary to Art. 36.1 ICBN. This name is a synonym.
Sansevieria erythraeae Mattei, Boll. Stud. Inform. Giardino Colon. 4: 170 (1918).

I did not recognize the description and picture John G. posted we seem to now be calling S. erythraeae aka S. schweinfurthii. I do have this plant, and my clone has no channels or grooves which I think shows in the attached picture. This species, according to J. Chahinian in his latest book might show a "round, shallow channel". Chahinian also says the leaves show "several longitudinal deeply impressed lines", but that could come from specimens that are dry. The leaves are normally upright and do not 'weep'.

How about a pic ?
there is a pic in my book somewhere which, after a brief search, I
believe has become buried in a drawer full of dog pedigrees. I know there
is a drawing of it with a broken leaf. the leaves are cylindrical and
do not fan at all, they are slightly wiggly but almost entirely
vertical.
