Looking for Wildflowers Along the Mohawk

April 28, 2014

By Steve Young

20140427-185313.jpgI took a stroll along the Mohawk Bike Path in Aqueduct, Niskayuna today to see what wildflowers I could find. The trail runs at the base of a slope where it meets the floodplain of small creeks flowing into the Mohawk River. Here are the wildflowers that greeted me along the way.

One of the first wildflowers visible was the beautiful bloodroot, Sanguinaria canadensis

Red elderberry flowers are still in bud and the leaves look strange.

Red elderberry flowers, Sambucus racemosa var. racemosa, are still in bud and the leaves look like something is affecting them.

Other wildflowers were still in leaf, like many of the violets, but I look forward to coming back with the Friday Field Group this week to see how far along thing are .

 

Carline Thistle Seen in Otsego County

September 6, 2012

Until now, the Carline thistle (Carlina vulgaris) has only been recorded for Cortland and Tompkins County, New York (see NYFA Atlas). Recently it was seen naturalized in fields in Otsego County by NYFA board member and botanist Connie Tedesco. The USDA Plants database only has it occurring in New York and New Jersey.  It is a Eurasian species that was introduced in the mid-1900s to New York.

The information at the NY state museum for this species shows it was collected for the first time in Cortland County in August, 1948 by R.T. Clausen “SE of Dryden Lake, Harford.” It was seen again south of Harford Mills in Cortland County by Stanley Smith Sept. 17, 1955. This is on the border of Tioga County. Arthur Cronquist reported it to the museum as common and spreading in Ithaca in 1983.

Is this a new invasive species on the move? If you see this plant naturalizing in your area please leave a comment at this blog entry.  Thanks. – Steve Young

Carex aggregata Rediscovered in New York

February 12, 2012

By Steve Young, NY Natural Heritage Program

In 2008 Heather Liljengren and Camille Joseph, staff members of the Greenbelt Native Plant Center in Staten Island, were collecting graminoids for seed preservation in Inwood Hill Park on the northern tip of Manhattan Island during the last week of May. They noticed a sedge that looked different and collected it to send off to Dr. Rob Naczi, a sedge expert at the New York Botanical Garden, for identification. Dr. Naczi confirmed it as glomerate sedge. Then in June 2009 Rob Naczi himself discovered it in the southwestern portion of the botanical garden grounds near the Bronx River during a survey of the plants of the Bronx Forest. Both of these discoveries were then reported to the Natural Heritage Program in 2011.

Only three populations of glomerate sedge have ever been reported from New York (there is also a Torrey specimen at NYBG with no location) which is at the northeastern edge of its range. It was first collected from the Perch Lake area of Jefferson County in 1949 then again in 1959 from the Spring Valley area of Rockland County. In 1988 Mike Oldham, a Heritage botanist from Ontario, collected it in Oakwood Cemetery during a trip to the Natural Areas conference in Syracuse. Another trip to the cemetery site in 1990 did not find the plants again. All of these collections occurred during the last week of May or in June. For 20 years there were no more collections or sightings of this sedge in New York until that day in Inwood Park.  This sedge now has the distinction of being the only state endangered or threatened plant that currently exists on Manhattan Island.

From the New York Natural Heritage Program conservation guides we have the following information about identifying this sedge: There are three other members of Carex section Phaestoglochin (C. sparganioides, C. cephaloidea, and C. gravida) that are similar.
Carex sparganioides is perhaps the most different from C. aggregata of these three. It has a more elongated inflorescences (3-15 cm long) with a larger proximal internode. In addition the widest leaf blades are 5-10 mm wide (Ball 2002).

Carex cephaloidea is the most similar to C. aggregata of the species that occur in New York. Carex cephaloidea has the widest leaf blades (4-)5-8 mm wide and the ligules are just longer than wide. In addition, the pistillate scales are 1.5-2 mm long, subobtuse to acute, and the bodies are no more than 0.5 times the length of the perigynia. Mackenzie in his description of C. aggregata (as C. agglomerata) used culm scabrousity to separate C. cephaloidea and C. aggregata. The angles of the culms of Carex cephaloidea being strongly serrulate while those of C. aggregata are only roughened just below the inflorescence. These character states may be incorrect or subtle.

Carex gravida does not occur in NY but was attributed to the state incorrectly in the past. It is not expected in the state. Carex gravida mainly differs in having the summit of the leaf sheath fronts white, hyaline, not thickened, and fragile.

Skunk Cabbage Starting to Appear

I checked our local red maple swamp today (no snow and 43 degrees) and the flower spathes of skunk cabbage are starting to poke up through the leaf litter but they haven’t opened yet. – Steve Young

It’s Not too Late in the Year for Botanical Discoveries

November 28, 2011

NYFA Board member Steven Daniel reported that he recently found a population of puttyroot, Aplectrum hyemale, in Monroe County. This is the second extant record for this orchid in New York, and the first verified report for Monroe County since 1895! Puttyroot is a curious orchid – like Calypso and Cranefly orchid (Tipularia) it puts out a single leaf in the fall. This leaf is able to photosynthesize (when it is not snow covered) when temperatures are above freezing. Come spring the leaf begins to wither, and is usually gone by the time the plant flowers, typically in late May or June.

This species can be easily overlooked. Look for puttyroot in rich beech-maple woods. Now is the best time to look for it. It will stand out in the mostly leaf covered forest floor, or with a fine dusting of snow. The leaves are distinctive with their pleating and white venation.

A Day on Long Island

September 10, 2011

I made a trip to Long Island recently and had the opportunity to see some interesting natural areas. – Steve Young

The beach at Goldsmith's County Park on the Long Island Sound side of the North Fork. Looks like some sand management is going on.

Some of the common beach plants include clotbur . .

and sea rocket, whose fruits actually look like little rockets ready to blast off.

On the dunes, masses of Rosa rugosa were in fruit.

Sea lavender was fairly common and in full flower.

Sea lavender, Limonium carolinianum, is our only representative of the Leadwort Family, Plumbaginaceae, in New York.

Spikegrass, Distichlis spicata, is also a common representative of salt marsh vegetation.

Saltmarsh-elder, Iva frutescens, one of our shrubby composites, was releasing pollen from its ragweed-like flower clusters.

It was sprinked on the opposite, succulent leaves below.

Prickly pear cactus was in among the dune plants but I didn't see any flowers or fruits.

Gray's flatsedge forms a clump of stems in the dunes. It has many rays in the inflorescence and bulbous roots if you dig it up.

In the woods closer to the road was a stand of sweet pepper-bush, Clethra alnifolia, in flower and in fruit.

West of Riverhead, I walked to a rare coastal plain pond to see that the water levels were up to the top. In drought years these ponds drain down to reveal many more plant species that are waiting patiently to germinate when the water is low.

It was raining a lot of the time but on the way back the sun came out to shine across the leaves of the pitch pine oak forest.

Glistening water droplets hung from the ends of the pitch pine needles.

An oak gall had dropped from a tree to the sandy trail.

Scores of new mushrooms were arising out the the sand in the trail too.

On the firebreak between forest patches an exotic catalpa has managed to survive, the only one I saw.

Since this visit Hurricane Irene has paid a visit to the Island and these forests probably look a little different now.  I’ll have to go back and see how they fared.

 

 

A Rare Plant Survey in Ulster County

June 25, 2011

Steve Young and Kim Smith of the New York Natural Heritage Program surveyed a state park in Ulster County this week. Besides Kim finding a new population of Carex davisii, these are some of the other things we saw.

The hophornbeams really stood out with their beautiful fruit clusters in contrast to the dark green leaves.

Sycamore maple, Acer pseudoplatanus, has escaped here. The "atropurpurea" cultivar has purple undersides.

Just outside the park were some impressive walls of Japanese knotweed.

At one point we had an aerial view of the tops of red oak crowns.

The crowns of large sassafras trees were also really neat to see.

We updated the information for a population of Virginia snakeroot, Endodeca serpentaria, a state endangered plant. It grows in the forest herb layer.

We found the small dry fruits under the leaf litter where the flowers of this cousin to wild ginger grow.

The purple-veined basal leaves of rattlesnake hawkweek, Hieracium venosum, were common in the deer-decimated understory.

Our botanizing drew the attention of this young barred owl who didn't seem to mind our presence.
