Notch x Uawa

CV. Notch is a named clone of Trichocereus pachanoi (San Pedro cactus) that comes from Ross Gurau's collection in New Zealand.
Here's what is known about CV. Notch:
Origin: It is a New Zealand Trichocereus pachanoi clone from Ross Gurau.
Characteristics: The name "Notch" suggests it may have distinct indentations or "notches" along its ribs. One source mentions "some notchy guys I grew from seed," implying this characteristic can be present.
Rarity/Circulation: It appears to be one of Ross Gurau's "less circulated" but "highly regarded" pachanoi clones. This indicates it might be less common than some of his other named varieties.
Breeding Parent: It has been used as a parent in crosses, as evidenced by a "Guru X Notch bb" (presumably meaning a seedling from a cross between Guru and Notch).
Ross Gurau's Cultivation: Ross Gurau is known for growing "a lot of old stands" very well and frequently shares pictures of his mature plants. His seeds are noted for being vital, sprouting quickly, and having high germination rates, as well as being "clean" with little chaff.

"Uawa" is a named cultivar (CV) of Trichocereus, specifically a hybrid. Here's what is known about it:
Type: 'Uawa' is primarily recognized as a Trichocereus hybrid, often appearing in crosses. One common cross mentioned is "Slimer x Uawa," which is further described as a "Melty scop x Fat pach." This suggests that 'Uawa' itself likely has genetic contributions from Trichocereus scopulicola ('scop') and Trichocereus pachanoi ('pach').
Origin: Seeds for 'Uawa' hybrids, such as "Slimer x Uawa," are noted to be "seedgrown" and come from Ross Gurau in New Zealand.
Characteristics (from hybrid descriptions): When crossed, 'Uawa' contributes to "mutant genetics" and "melty" characteristics, combined with the "fat pach" qualities. This implies it might have unusual growth forms or tendencies to exhibit monstrose or crested traits.
Availability: Plants resulting from 'Uawa' crosses (like "Slimer x Uawa") are sold online, for example, on eBay Australia.
Related to Other Cultivars: The "Melty scop" parent in "Slimer x Uawa" refers to Trichocereus scopulicola, and "Fat pach" refers to a stout form of Trichocereus pachanoi. This highlights its place within the broader Trichocereus family of columnar cacti, which includes well-known species like San Pedro (Trichocereus pachanoi) and Peruvian Torch (Trichocereus peruvianus).
