It's Agalinis time!

Agalinis, the false foxgloves, bloom primarily in the fall. Some species are common and widespread, others are very rare, possibly extirpated in Texas, or very localized.

For those in the Tarrant Co. area, A. auriculata was documented long ago but hasn't been seen since. Is it still hanging on in some out-of-the-way place?

Along the Red River, A. aspera may occur. It's been found on the north side of the river, but not the south side.

The identifying characteristics can be quite subtle, so photographs of from multiple angles of all the critical characteristics is important. See the guide for details.

We've already had one new iNat record of A. densiflora (@pufferchung!). It's distribution is very poorly documented. So keep an eye out for it (primarily in sandy soils). Here's a map of some museum records for Agalinis densiflora. It occurs beyond these locations, but there are some places where we lack iNat records (and we have some iNat records that lack museum records).

Thanks for the guide, it's very helpful. I need to remember to bring a ruler.

For a while there, I thought we had lost @pfau_tarleton forever to the spiders. That A. densiflora is very interesting. I was not aware of it. It is interesting how the BONAP record for it kind of hops over the Austin area (Travis, Williamson, and Burnet counties) before picking up again to the south.

Took a quick look for A. densiflora in iNat observations of Burnet, Williamson, Blanco, Hays, Comal, Bexar, and Guadalupe counties and nothing jumped out at me. Though BONAP lists it as being present in Blanco, Hays, Comal, Bexar, and Guadalupe, I could only find records on SEInet for Hays (from 1948) and Bexar/Comal (Lindheimer collections from Comanche Springs from the 1850s), so if there are records from Blanco and Guadalupe, they may be from other herbaria. Anyway, it looks like it would be extraordinarily rare in this part of its range.

@rymcdaniel, I'm still a taxonomical polyglot! Despite the spiders hogging some of the spotlight here lately.
