When first described in 1999 from collections from southern Aramberri in southern Nuevo León, México, Paul Peterson suggested Muhlenbergia jaime-hintonii resided in M. subg. Trichochloa, perhaps related to M. pubigluma since both species share a dense white pubescence below the basal nodes, short-leafy rhizomes, reddish-gray spikelets, and faintly-3-veined lemmas. However, after producing a phylogeny based on DNA sequence markers in 2010, 2018, and 2021, M. jaime-hintonii was found on an isolated branch embedded within species residing in M. subg. Pseudosporobolus near other wide-ranging species from the Great Basin and Eastern North America.
Alice Tangerini inked the plate using the Gillott crowquills on drafting film. The illustration marked the initial scanning at high resolution for artwork in the department. The drawing was scanned at 1200 dpi which was twice the former scan resolution of 600 dpi. Tangerini spoke with Barney Lipscomb, SIDA’s editor, and requested the high resolution for the page. Lipscomb agreed to 1000 dpi which was all they could handle and the file was then reproduced in bitmap to keep the file size small. The resulting reproduction in SIDA (18: 686; 1999) looked very sharp and set the standard for all following illustrations.
