Re: Extrafloral nectaries in cacti

Yes Mrs Green, an interesting article, many do not realise extrafloral nectaries are found on quite a few cacti. It's one way for cacti to get ants to protect them by keeping other sap sucking or chewing pests off them. Unfortunately mealy bugs and aphids have developed the same ruse to get around i...

Re: Most popular cactus sold?

Many cacti are sold as said as the equivalent of "cut flowers" to be binned when the interest is past, hence the stuck on flowers and faces as gimmicks to sell them. Collectors are a dead loss to this trade since once they have a specimen of that species they are not in the market for anot...

Re: Where did everyone go.

The main problem I think was the change of the board and being offline for so long? After the first few weeks some have probably not even tried to see if we are online again and moved elsewhere. People are creatures of habit and once they get used to doing something else with that time often do not ...

Re: Most popular cactus sold?

Things also vary with time. Plants once popular go out of favour and nurserymen stop propagating them. Obviously for the casual plant market nurserymen propagate stuff that can either easily be grown from offsets, or seed grown Cerei that make a large saleable plant quickly. Also the most attractive...

Re: If possible, ID please

I agree with anttisepp, if green bodied its more likely Parodia (Eriocactus-Notocactus) warasii. I find unlike most of the Eriocactus group warasii often offsets further up the stem, as in your 3rd picture, rather than originally basally offsetting as most cacti do. This seems normal for the species...

Re: Any help appreciated, Mammillaria sp.

Yes there are a few forms in the M. hahniana group, mainly varying according to the amount of hair produced. Whether you keep them as separate species or just reduced to varieties is a matter of opinion. There were two good Mammllaria's of the Month articles covering them here:- http://mammillaria.n...

Re: Rebutia muscula?

Yes as Bryan says it could be R. flavistyla, which is another floriferous plant. Again it is hard to identify many Rebutia's without flowers.

Re: Rebutia muscula?

Hard to tell, flowers would help as they are a characteristic orange colour. Generally R. muscula (the name means "mouse like", a reference to its "furry spines") is denser spined, but that could just be cultivation so far.

My Rebutia muscula.

Re: Nobody lives forever...

Yes, in dry habitats plants don't tend to rot away as in moister ones and so return as normal organic matter to the soil, but soon dry out and turn to dust. An old British cactus grower in the 1960's used to maintain cacti simply turn to dust or mineralise in dry climates and return to desert soils ...

Re: Nobody lives forever...

Everything has a lifespan. With cacti it can range from around 5-8 years or so with some tiny Mammilaria's to 250 years with a Carnegia (Saguaro). Plants possibly live longer in cultivation than they do in the wild, provided we do not kill them through poor cultivation. But nothing lasts forever as ...

Re: For how long must a cactus have been in your care, before you can take credit for its flowering?

As Xeric implies there was an old saying "a near death experience will encourage some planta's to flower" obviously in order to pass on their genes in the form of seed that can withstand conditions in habitat that may kill the plants themselves. Maybe not entirely true, but hard grown plan...
