what is LAU 1116 ?

this is LAU 116 sowed by "ento" ennio toso - savona

I am sure you mean L 1116 as L 116 is Submatucana ritteri.

When Lau collected L 1116 in 8-4-77, he named it M.sp. Later he gave it the name M.lanata. Hunt then showed that lanata was a redescription of M.supertextea.

How much the above young plant is to the original plant that Lau collected in 1977 remains to be seen.

Yes, i wanted to say LAU 1116. sorry.

have you an old LAU 1116 to show me?

This plant doesn't look much like M. supertexta to me, not with those very obvious central spines. M. supertexta is one of those old names into which people have put a range of plants, some with other names. The description allows for 2 central spines, only 3mm long, some dark tipped. Other populations appear to broaden the description with central spines up to 5mm long, darker. Yet again, other populations seem to have no central spines, and these appear to have been called M. lanata.

The photo of the plant from Ento has 4 central spines, so is quite different from the description, at least. I have a plant labelled L1116 that I grew from Mesa Garden seed 917.9, germinated in 1992. Here is what this plant looks like - if indeed it is true! To me, this has a bit of crucigera in it, though it certainly isn't that plant, or even huitzilopochtlii.



Lau found L1116 west of Cuicatlan, on the Rio Obos, in Oaxaca. This fits pretty well with the distribution of M. supertexta. His L1158 is believed tt be the closest plant found to the original description is also from that area. It would be good to have that plant as a comparison. Has anyone got it still?

I sowed Maurillio plant in 2007, De Hert seeds, from the catalog " sp.Lau1116 de Tres Picos-Cuicatlan/oax"
I have two other plants sp, Lau1116, a gift from a friend on the label "sp. Lau 1116 crucigera"
and other plant purchased a Italian nursery , label " sp. Lau 1116 supertexta"


sp Lau 1116 de Tres Picos-Cuicatlan/Oax

sp. Lau1116 crucigera

sp. Lau1116 supertexta

A very variable plant? or hybridised seed?
Very strange!!

this is LAU 1116 from prof. carlo zanovello private collection in flower to-day 08 february 2011..


LAU 1116 - de tres picos, cuicatlan - oaxaca - mexico

In the CACTUS AND SUCC. J. (U.S.) Vol.63 3/1991 you'll find a original foto from LAU of his L1116 in habitat. The plant looks like the third one from ento (supertexta).
LAU compares L1116 with M.conspicua. APPENZELLER, who wrote the article, recognize a great similarity to M.huitzilopochtlii and to M.crucigera.

Had a word with TAM this week about my L1116 and ROG139b both purchased from him early in May/June. I was generally checking over my recent acquisitions and noticed the similarity of the above plants. In L1116 my plant looks like Entos third plant with many more central spines, which are about 5mm. long, looking very much likeROG139b labelled Dixanthocentron ! Normally,my perseption of Supertexta is a tight, white spined plant .

I'd agree, my perception of supertexta is a short spined, tight plant, with a variable number (0 to 2) central spines very short, usually shorter than the raidals.

I think that there must be, in habitat, a lot of intermediate forms, between supertexta, crucigera (in all its currently accepted subspecies), huitzilopochtlii, and even haageana.

I have travelled through this area in southern Puebla and northern Oaxaca, and made a number of stops, but nowhere near enough to form any firm opinions.

But the plants shown in the photos earlier in this thread, to my mind, show how easy it is to mix up seedlings, lose labels, make mistakes etc. Which is the right one? Probably the one referred to in the 1991 CSJA, but I'm away from home so can't chekc it out until after I return from ELK.
