- First described
- 2012
- Type
- registered cultivar yellow flowered leucophylla x alata
Origin
Citronelle Bog, Washington Co, Alabama — confirmed by sarraceniaobsessed (post #5, 2012) after Mike's initial Mobile-or- Washington speculation. Named for Don Schnell. Registered cultivar; description in CPN v30n1p11-14 (philiptdotcom, post #7, 2022).
History
- Pre-2001 [VERIFY]: registered in CPN v30n1.
- 2012-08-13 (post #1): Mike posts the clone, hypothesizing a (leucophylla × alata) × leucophylla backcross genetic origin (yellow flower in a non-anthocyanin-free body suggests historical alata gene contribution).
- 2012-08-29 (stevebooth, post #2): raises whether green-veined interior disqualifies it from var. alba designation.
- 2012-08-30 (Mike, post #3): defends including it in var. alba by parallel with HCW Clone E's plasticity.
- 2012-10-01 (sarraceniaobsessed, post #5): confirms Citronelle Bog provenance.
- 2022-04-26 (philiptdotcom, post #7): links the formal CPN cultivar description.
- 2023-07-30 (alexis, post #8): identifies as MK L139 and posts a 2023 yellow-flowered cross derivative.
Standout traits
- Yellow flower — diagnostic for the alata-introgression hypothesis, since pure leucophylla has red/maroon flowers.
- Heavy white panel.
- Phenotypic plasticity in vein expression — green-veined or solid-white interior depending on conditions.
Cultivation notes
[MISSING] — no cultivation-specific advice in this thread. Standard leucophylla / var. alba husbandry is implied.
Photos
6 Mike-Wang photos from August 2012. Note: post #1573 photos are HCW Clone E used as a comparative example; they are not catalogued here (they belong to the HCW Clone E entry).
Standout traits
- Yellow flower despite NOT being anthocyanin-free — Mike (post #1, 2012) suspects (leucophylla × alata) × leucophylla backcross
- Heavy white panel — strong enough to be considered an alba
- Green-vein interior under some conditions, solid-white interior under others — same clone, different environments
- alexis (post #8, 2023): 'a fantastic alba'
Cultivation
Phenotypic plasticity in vein expression — environment, not genetics, determines whether interior shows green veining or pure white in any given trap. Steve Booth (post #2, 2012) raised the taxonomic question of how var. alba should be defined when the same clone exhibits both phenotypes seasonally; Mike's pragmatic reply (post #3): the Stewart McPherson definition probably needs to accommodate this kind of plasticity.

Naming
Named for Don Schnell, the late Sarracenia authority. "Ghost" = the heavy white panel.
