| Abstract |
Paphiopedilum rungsuriyanum from Northern Laos was discovered and described in 2014. It is characterized by having miniature tessellated leaves, a flower having a helmet shaped lip with a V-shaped neckline, and a semi-lunate, 3-dentate staminode with an umbo. These morphological features distinguish P. rungsuriyanum from the other known sections/subgenera of Paphiopedilum, making it difficult to group with existing infrageneric units. Paphiopedilum rungsuriyanum has chromosome number of 2n = 26. Fluorescence in situ hybridization study demonstrates that there are two 45S rDNA signals in the telomeric region of chromosomes, and more than 20 5S rDNA signals dispersed signals in the pericentromeric and centromeric regions. Phylogenetic analyses based on four nuclear (i.e. ITS, ACO, DEF4 and RAD51) and four plastid (i.e. atpI-atpH, matK, trnS-trnfM and ycf1) gene regions indicate that P. rungsuriyanum is nested in subgenus Paphiopedilum and is a sister to section Paphiopedilum. The results in combination with karyomorphological, rDNA FISH patterns, morphological and phylogenetic analyses suggest a new section Laosianum to accommodate this species in the current sectional circumscription of subgenus Paphiopedilum. |

Attention Score in Context
This research output has an Altmetric Attention Score of 5. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 15 January 2023.
All research outputs
#7,208,166
of 25,382,440 outputs
Outputs from Botanical Studies
#36
of 188 outputs
Outputs of similar age
#108,109
of 323,203 outputs
Outputs of similar age from Botanical Studies
#3
of 7 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one has received more attention than most of these and is in the 71st percentile.
So far Altmetric has tracked 188 research outputs from this source. They receive a mean Attention Score of 4.5. This one has done well, scoring higher than 79% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 323,203 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 66% of its contemporaries.
We're also able to compare this research output to 7 others from the same source and published within six weeks on either side of this one. This one has scored higher than 4 of them.
