Discussion on Labiatæ: Conclusion

If the Satureieae (with only 405 sp. having betw 1/5 & 1/6 of order) be removed, the Labiatæ then have in big genera 98/1000 & in small 80/1000. The Sat. have 131/1000 & 182/1000. I think the proportion throughout order (certainty in order after Sat. have been subtracted, the vars bear remarkable proportion to varying species.

In Babington the larger genera have more varying species. So in Ledebour

In Boreau the smaller genera have most varying species so they have in Koch; so they have in Visiani

Grisebach & Asa Gray too few vars to judge by

Labiatæ divided equally have in larger gen 1.20 vars to sp. in spec 1.53 vars to species

They have when divided into 11 sp & up & 10 & dn 1.34 - 1.62

Equally 99/1000 – 1.7 Labiatae

Gen with 17 sp & up 105/1000 1.35

[illeg] /1000 1.53

Gen with 16—8 with 175-1000 1.22

Sections of 8 largest genera in Labiatæ, divided into 98 [+] 6 [=] 104 sections

Larger sections 48 sections / 546 speces = 88/1000

Smaller Sections 66/512 = 128/1000 so smaller sections increasing largely.

The 2 gigantic genera with 653 species have varying sp in proportion of 90/1000 & vars to species, only 1.20
