Plant Species of the South Kaibab Trail:
little-leaved mountain-mahogany, Cercocarpus intricatus

See Plant Guide to South Kaibab Trail for an introduction to this page, especially the Introduction To These Species Pages.

This page is just a shell to hold my photographs for now, along with very cryptic notes I made from the identification process, so that readers can see the photographs of this taxon. The identification status, voucher info, and discussion of the species will be added in the future.


Identification status: .

It keys well in Mcdougall:

1   shrub
2'  fruit not applelike
7   no id in 7'
8'  fruit an achene
10' lvs alt
11' lvs entire
12' lvs narrowly linear, strongly rolled with little more than the midrib
    of the lower surface exposed ...  C. intricatus

Oddly, though, the description says the leaves are "smooth". Yet they are clearly very hairy; look at all the red trail dust adhering to those hairs in my pix!

Fortunately, the USDA plants page has pix which match our plants, including the hairy leaves.

This species is in the Jepson Manual, from SNH and DMtns, which says the upper leaf surface is "gen +- glabrous" for the genus, making no exception for C. intricatus. weird... Munz says "young growth pubescent", which is more like it.

There are vouchers from the Grandview Trail, and from the same elevations near the Redwall in other places.

From a SEINet search on 8 September 2008, there are vouchers of this species from the Coconino County portion of the Grand Canyon. The nearest are at: ; and . Note that there may be additional vouchers at other herbaria not available through SEINet.

First occurrence on South Kaibab Trail: mile 2.03, elevation ~5500 feet (~1675 m).

Number of plants along Trail: at least 3 plants were found in at least 2different locations in August 2008.


From 24 August 2008, mile 2.03:
