One Malawi (the Equilibrium that FDM used) is an acclimatized heirloom from the mountains around Santa Cruz:
“These are F1 hybrids of an Heirloom Sativa 
from the Santa Cruz Mountains. This Malawi has been stabilized for a number of traits including tall height, hollow stems, light green leaves, chunky + medium dense buds, sweet aroma, high THC and mold resistance.”
The other (in @Roms AfroBubble) is Afropips Power Malawi, which is Jim’s Malawi Gold x Pure Power Plant. I found this from him about his Malawi Gold in a good ICMag thread about it:
Great Read Guys!
Sativas definately Rock my World!
I have travelled around Africa & the most delicious
Buds I tasted was the Mozambique Black which
matches the description of the African Black
(A bag of the worst looking blk leafy bud)
& the Malawi Black scored in the Malawi Cob,
The buds were dark brown to black with tons
of blk sticky resin, compact & wet
& needed to be cut with the scissors.
I grew up in Durban & spent a good 10 years smoking
the original Durban Poison sticks wrapped in Bookie Papers.
Later they halved the size & used brown paper & were
known as Pietermaritzburg slugs. They come in a roll of 20 sticks,
resemble & are named after the revolver bullets.
I just popped a few of the PMBurg Slug seeds on the week end.
Eventually I got tired of the DP & went to the Transkei
for a couple of months. Here I stayed on several grower / Herbalist
plantations & sampled The Pondo Fever.
It was here in 1985 when I learnt how to take cuttings from
Julius the Best Grower in the Coffee Bay Area at the time.
Swaziland was the next destination as we ocasionally used to get the
Swazi Brick shipments in SA. It had a very fruity pepper taste
& was known as Royal Swazi.
We scored the Best heads from the Piggs Peak Area.
Swazi Grease was something special - A black hash with the resemblace of grease.
You had to wrap a matchstick dipped in grease & spread into the herb to smoke it.
In the early 80’s a good friend of mine visited with a Malawi Gold Cob
his friend brought back with him from a holiday in Malawi.
We smoked a bottleneck amongst a few spa & puffed a few joints,
needless to say I was hooked.
The next ganja hunt was off to Zimbabwe in 86.
The Best we scored was the Batonka weed which was comparable to the
Mz & Mal Blks. The buds were the size & shape of Goons & Golf Balls.
The Mutoka weed had some interesting buds but were not
really Hard enough when the staple was Malawi Cobs which are readily available in Harare.
In 1992 I took my first trip to the Lake Malawi to
visit the place where the number one smoke was
coming from & stayed a couple of months.
Later I would spend half my time there & the other half in Zim
until I came to UK in 1999.
The First Grade Malawi Gold is definately my no1
choice of landrace sativas.
The Gold takes you to where you wish to be
with the unique Malawi Gold Taste, Aroma & Effect.
It is very similar to Thai weed in taste & aroma
but has the spicy gum numbing, vision distorting effect.
Its extremely Mellow & smooth to taste &
a warm glow comes over the whole body when
you come to the end of the Joint.
Here is Chizzle Pic of an opened Malawi Gold Cob
for those who have never seen the Malawi
traditional way of packaging & curing.
Notice the light green to gold colour.
