Echeveria Lau 165

[MikeT]

I acquired a couple of Echeverias last year through the Sedum Society cuttings exchange, with the names Lau 165 & Lau 026. The collection numbers actually relate to cacti (Arequipa & Echinocereus according to Ralph Martin's Field Number Database on the Cactus mall site).
Googling for Echeveria Lau 026 gives E. subcorymbosa, but I can't find anything on Lau 165. Does anyone have any info on this? I'll add pics of both. 165 is bluer than the photo suggests.

Lau 26 = subcorymbosa

There's something bizzarre about Alfred Lau's numbers. Lau 26 in the database does, as you say, give Echinocereus brandegeei. I've been sorting/browsing some old journals today and remembered coming across a list of Lau numbers. I've re-found it (National Cactus and Succulent Journal 1980, 35(2), p.47-49) and that lists L026 as Mammilaria brandegeei, which is a real species. One or other must be an error, probably the NCSJ version? (Hard to say as both are supposed to come from Baja California, Mexico, which accompanies the NCSJ listing) What's doubly odd is that it only lists numbers 001 to 099 and 600 to 699. No mention is made of the intervening numbers (which would have been useful in the discussion of Echinopsis L400 a few weeks ago). The article does have the title "Alfred Lau Collection Numbers (1)" which does suggest there was a (2), but my copy is an oddment. Any longstanding NCSS/BCSS members got journals for Sept or Dec 1980 or 1981 who could help here? Not a single plant in the ranges listed is a non-cactus, so that's no help either.

In Pilbeam Lau023 is Mammillaria brandegeei and there is no Lau026 for any Mammillaria species so I presume the database is correct. Sorry I can't help with the Echeveria.

Twas I that compiled the list of Alfred Lau numbers way back in the late 1970s. On the list that I sent to the then editor of the Nat.Cactus and Suc.Journal Lau 026 is shown as Echinocereus Brandegeei from El Arco Baja California but the Journal showed it as Mam.Brandegeei from San Ignacio which was in fact Lau 023. Don't ask me why. Part 2 of the list was never published so there is no point in looking for it. Again I don't know why. The original list was sent to all importers of Lau's plants and was concocted by Alfred Lau himself.

This may be of interest, it describes the same plant whatever we might make of the collection number.

Ooooo small world! Can you shed any light on why the numbers go 1-99 and then 600-699? And can we get any closer to identifying those Echeverias or L400? Were these in part (2)?

[John E]

All the Lau numbers up to Lau059 were collected in Baja California. I am not sure if this is of any use but this is a copy of the original list sent by Lau to importers

I have a booklet of Lau numbers giving details of no's 1-1536.
in this 026 = "Echinocereus brandegeei,pink centre spines, El Arco,B.C."
& 165 = "Arequipa erectocylindrica,Caraveli, Peru" I have looked at a couple of other possibilities (1165 = a Mamm) with no joy yet.

I was AWOL at the time of the L400 thread! My booklet gives- " Echinopsis sp. (hamatacantha?), Entre Rios, Bolivia"

Hope this helps a bit!

Hi Rob,

1165 is (crinita) leucantha from Sierra de San Miguel, SLP
